Description:
Productoverview: ZW-YF-1 seriesThermal simulation instrument calibrationIs a powerful and easy to use calibrator.Measurement and signal output function can be almost any process parameter test and calibration in addition to outside pressure.Design of a series of test instrument, the operation is very simple. Two, work principle: ZW-YF-1 seriesThermal simulation instrument calibrationThe principle is the current to be measured by high precision electronic compensating transformer built-in, namely direct access measurement, or electronic compensating transformer clamp (clamp meter), the measured current is converted to the appropriate signal amplitude small current, by precision resistor sampling into a voltage signal sent to A / D devices the accuracy of the appropriate sampling rate will be converted into digital signal instantaneous flow.Digital signal measured voltage and current to the FPGA logic circuit in transmission using photoelectric coupler to achieve electric isolation circuit under test and test system. To ensure the stability of the safety test and test data. Three, widely used: ZW-YF-1 seriesThermal simulation instrument calibrationIs a high performance portable calibrator, with galvanic measurement and output function is very professional.You can test and calibration of temperature transmitter, temperature display instrument and data acquisition system, and can directly measure the temperature thermocouple connected circuit. Four, main features: 1, reasonable structure, compact and firm, self-contained battery, easy to replace. 2, check instrument field and field operation is very convenient. 3, rich software to check the instrument has the advantages of simple operation, easy.Zero calibrator, linearity, temperature drift free. 4, in addition to self correction ability, through the keyboard to adjust at any time. By measuring and computing ability of the thermocouple indexing table signal survey in 5, a full range of industry.Can B, E, EA signal, J, K, N, R, S, T and other nine kinds of commonly used thermocouple, DC 24V and 0~20mA output current measurement can be SD-403 type signal transmission instrument calibration. Five, technical parameters: 1, voltage measurement range: 0~ + 1000mV: accuracy: + 0.05%; Input impedance: 2, 10M. "; Output: 3, range: 0~ + 100mV: < 0.5 ohm impedance; 4, current: 0~ + 20mA + 0.05%: accuracy of input impedance of about 5; 5, 24V DC voltage output, load 30mA; 6, size: 223*96*55. Six, the conditions of use: 1, power: 6V Ni MH (Li ion) battery, charging, 220VAC, 5Hz; 2, temperature: 0~50 degrees (beyond the temperature range, accuracy drops); 3, humidity: 0 ~ 85%RH; 4, the environment: no corrosive gas. Seven, the basic functional requirements: 1, work out the requirements of volume to be as small as possible, light weight as much as possible; 2, the work site does not work station, the calibrator in most cases is placed on the ground to work with; 3, on-site measurement data required to reliably store data, and can conveniently exchange; 4, if there is a need for energy measurement error, requires the tester must first be a standard electric energy meter, and should be a convenient operation, high precision, multifunctional and intelligent electric energy meter; 5, sometimes the need for on-site wiring inspection, which requires the calibrator required to display vector analysis, vector diagram and wiring diagram, line identification phase, so the test instrument is a table and vector analysis software combined with standard electric energy.
