Instrument OSLIM optical silt measuring instrument The OSLIM optical silt measuring system is an instrument to measure concentrations of suspended particles. The measuring principle is based on the attenuation of the intensity of light passing through the measuring volume. The light is absorbed and scattered on suspended silt particles. The output is presented as an analogue voltage. The OSLIM system consists of a probe and a control unit. The control unit provides the system with power, controls and switches for setting the zero, span, out-of-range detection and analogue output. The particle suspension is to pass the OSLIM probe, e.g. by pumping. Applications Fields of application for this instrument are: Analysis of suspended sediment samples Monitoring of suspended matter in liquids Features Two probe types, 1.6 and 5.0 mm (ID) tubing Easy to clean probe parts OSLIM probe Exchangeable transmitter and receiver Electronics insulated from medium Immersible version available OSLIM control unit Instrument, OSLIM optical silt measuring instrument v1.1 Technical specifications of the probe (standard) Materials brass glass tubing Dimensions 1.6 mm probe: 25 x 80 mm (d x l) 5.0 mm probe: 30 x 100 mm (d x l) cable: 2.5 m Weigth 1.6 mm probe: 0.15 kg 5.0 mm probe: 0.25 kg Technical specifications of the control unit Housing the OSLIM control unit is housed in an IP60 protected aluminum box with separate mains adapter Range 1.6 mm type and pump-flow > 1 cm3/s: 5, 10, 20 and 50 g/l (China clay) 5.0 mm type and pump-flow > 3 cm3/s: 1, 2, 5 and 10 g/l (China clay) Zero-stability < 0.4%/24 hours of full scale Response 20 ms Controls range selector span and zero setting overload indicator Output analogue voltage, 0-10 VDC Connectors output (BNC) probe socket mains socket (24 VAC) Mains adapter 230 VAC/24 VAC Dimensions 120 x 120 x 100 mm Weight 1.9 kg .

Calibration Methods – Nomenclature and Classification
CHAPTER 8 CALIBRATION METHODS – NOMENCLATURE AND CLASSIFICATION Paweł Kościelniak Institute of Analytical Chemistry, Faculty of Chemistry, Jagiellonian University, R. Ingardena 3, 30-060 Kraków, Poland ABSTRACT Reviewing the analytical literature, including academic textbooks, one can notice that in fact there is no precise and clear terminology dealing with the analytical calibration. Especially a great confusion exists in nomenclature related to the calibration methods: not only different names are used with reference to a given method, but they do not express the principles and the nature of different methods properly (e.g. "the set of standard method" or "the internal standard method"). The problem mentioned above is of great importance. A lack of good terminology can be a source of misunderstandings and, consequently, can be even a reason of carrying out an analytical treatment against the rules. Finally, the aspect of rather psychological nature is worth to be stressed, namely just an analyst is (or should be at least) especially sensitive to such terms as "order" and "purity" irrespectively of what analytical area is considered. Chapter 8 1 INTRODUCTION Reading the professional literature, one is bound to arrive at the conclusion that in analytical chemistry there is a lack of clearly defined, current nomenclature relating to the problems of analytical calibration. It is characteristic that, among other things, in spite of the inevitable necessity of carrying out calibration in instrumental analysis and the common usage of the term ‘analytical calibration’ itself, it is not defined even in texts on nomenclature problems in chemistry [1,2], or otherwise the definitions are not connected with analytical practice [3].

A Measuring Instrument for Multipoint Soil Temperature Underground
A MEASURING INSTRUMENT FOR MULTIPOINT SOIL TEMPERATURE UNDERGROUND Cheng Wang, Chunjiang Zhao * , Xiaojun Qiao, Zhilong Xu National Engineering Research Center for Information Technology in Agriculture, Beijing, P. R. China, 100097 * Corresponding author, Address: Shuguang Huayuan Middle Road 11#, Beijing, 100097, P. R. China, Tel: +86-10-51503411, Fax: +86-10-51503449, Email: [email protected] Abstract: A new measuring instrument for 10 points soil temperatures in 0–50 centimeters depth underground was designed. System was based on Silicon Laboratories’ MCU C8051F310, single chip digital temperature sensor DS18B20, and other peripheral circuits. It was simultaneously able to measure, memory and display, and also convey data to computer via a standard RS232 interface. Keywords: Multi-point Soil Temperature; Portable; DS18B20; C8051F310 1. INTRODUCTION The temperature of soil is a vital environmental factor, which directly influences the activity of microorganisms and the decomposition of organic substances. It can affect roots absorbing water and mineral elements. It also plays an important role in the growth rate and range of roots. Statistically, roots of most plants are within 50 centimeters underground, so it becomes very significant to measure the soil temperature of different depth in this level. The Soil Temperature Measuring Instruments used nowadays mainly fall into three types, the first type is the measure temperature by making use of the relationship between the soil temperature and the temperature-sensitive resistor. Before using this sort of instruments, the system parameters need to Wang, C., Zhao, C., Qiao, X. and Xu, Z., 2008, in IFIP International Federation for Information Processing, Volume 259; Computer and Computing Technologies in Agriculture, Vol.

With this method, you do not have to reset the system to zero after turning it off and then turning it on. The position information recorded on the scale is read every time. The following three types of absolute encoders are available: electrostatic capacitance model, electromagnetic induction model and model combining the electrostatic capacitance and optical methods. These encoders are widely used in a variety of measuring instruments as the length measuring system that can generate highly reliable measurement data. Advantages: 1. No count error occurs even if you move the slider or spindle extremely rapidly. 2. You do not have to reset the system to zero when turning on the system after turning it off*1.

I Introduction to Measurement and Data Analysis
I Introduction to Measurement and Data Analysis Introduction to Measurement In physics lab the activity in which you will most frequently be engaged is measuring things. Using a wide variety of measuring instruments you will measure times, temperatures, masses, forces, speeds, frequencies, energies, and many more physical quantities. Your tools will span a range of technologies from the simple (such as a ruler) to the complex (perhaps a digital computer). Certainly it would be worthwhile to devote a little time and thought to some of the details of \measuring things" that may have not yet occurred to you. True Value - How Tall? At first thought you might suppose that the goal of measurement is a very straightforward one: find the true value of the thing being measured. Alas, things are seldom as simple as we would like. Consider the following \case study." Suppose you wished to measure how your lab partner's height. One way might be to simply look at him or her and estimate, \Oh, about five-nine," meaning five feet, nine inches tall. Of course you couldn't be sure that five-eight or five-ten, or even five-eleven might be a better estimate. In other words, your measurement (estimate) is uncertain by some amount, perhaps an inch or two either way. The \true value" lies somewhere within a range of uncertainty and one way to express this notion is to say that your partner's height is five feet, nine inches plus or minus two inches or 69 ± 2 inches. It should begin to be clear that at least one of the goals of measurement is to reduce the uncertainty to as small an amount as is feasible and useful.

Experiment Zero (Lab Intro) Spring 2021 PHYS221 Introduction to Measurement & Error Analysis Data Sheet
Experiment zero (Lab intro) Spring 2021 PHYS221 Introduction to measurement & error analysis data sheet http://relativity.phy.olemiss.edu/~thomas/ NAME________________________ Section_____ Date_________ In this lab you will measure various quantities using either an analog device (which does not have a digital display, e.g., a ruler or triple beam balance) or a device with a digital display (e.g., a digital caliper). The readability (or precision) of any type of device is defined as the smallest quantity that can be read from (i.e., measured by) that device. The uncertainty of an analog device is generally (but not always) defined as ½ of the readability of the scale. The uncertainty of a digital device is generally defined as the readability of the digital display. Part one- Readability and uncertainty of a measuring instrument Instrument Readability Uncertainty (include units) (include units) ruler +/- protractor +/- triple beam balance +/- electronic (digital) balance +/- Vernier caliper Use readability +/- Part two-Measurement of dimensions of metal block. Please note that dimensions (lengths) of the sides of the blocks are denoted as long, medium and short. All measurements must have units when applicable and all uncertainties should be written using one significant figure. For example (51.5 +/- 0.5) cm. This can also be written as 51.5 +/- 0.5 cm Length ± Absolute uncertainty of length Dimension (length) Ruler Caliper measured (include units) (include units) long±δlong medium±δmedium short±δshort 25.40 +/- mm How to calculate fractional of percent error. Say you are given a measurement with an absolute uncertainty of (51.5 +/- 0.5) cm. To convert to fractional (percent) uncertainty you would do the following calculation: Experiment zero (Lab intro) Spring 2021 PHYS221 Introduction to measurement & error analysis data sheet http://relativity.phy.olemiss.edu/~thomas/ 0.5 �� × 100 (51.5 ± 0.5)�� → 51.5 �� ± → 51.5 �� ± 0.9709 %.

Quantum Dynamics of a Small Symmetry Breaking Measurement
Quantum dynamics of a small symmetry breaking measurement device H. C. Donkera, H. De Raedtb, M. I. Katsnelsona,∗ aRadboud University, Institute for Molecules and Materials, Heyendaalseweg 135, NL-6525AJ Nijmegen, The Netherlands bZernike Institute for Advanced Materials, University of Groningen, Nijenborgh 4, NL-9747 AG Groningen, The Netherlands Abstract A quantum measuring instrument is constructed that utilises symmetry break- ing to enhance a microscopic signal. The entire quantum system consists of a system-apparatus-environment triad that is composed of a small set of spin-1/2 particles. The apparatus is a ferromagnet that measures the z-component of a single spin. A full quantum many-body calculation allows for a careful ex- amination of the loss of phase coherence, the formation and ampliﬁcation of system-apparatus correlations, the irreversibility of registration, the fault toler- ance, and the bias of the device. 1. Introduction Bohr, in his discussions with Einstein [1], repeatedly emphasised that each peculiar feature or seemingly paradoxical phenomenon in quantum mechanics, is always to be viewed in the light of the experimental arrangement that is used to interrogate the quantal test object (e.g., an electron or atom). But if one takes seriously the idea that the laws of quantum mechanics are universally valid, then, in turn, the measurement instrument itself must obey the laws of quantum mechanics. The ﬁrst attempt to consolidate the internal consistency of measurement and quantum theory was by von Neumann [2]. By detailing measurement as a non-unitary disruption of the density operator to diagonal arXiv:1804.08151v1 [quant-ph] 22 Apr 2018 form (in the basis determined by the measurement), von Neumann noted that the same result can be accomplished by considering an enlarged quantum sys- tem in which the Hilbert space is partitioned in two AB = A B [2].
