Product Details
| ZY-600 series intelligent digital display instrumentDetailed information: |
|
overview ZY-600The series of intelligent digital instruments adopts high-performance and highly anti-interference integrated instrument chips. The measurement input and transmitter output adopt digital calibration and self calibration technology, which ensures accurate and stable measurement and eliminates measurement errors caused by temperature drift. And throughEMCElectromagnetic compatibility testing has strong anti-interference ability, high reliability, and high cost-effectiveness.
ZY-600The series of instruments have programmable functions for multiple types of inputs, and one instrument can be paired with different input signals (thermocouples)/thermal resistance/Linear voltage/linear current/linear resistance/At the same time, the display range and alarm control can be set by the user on-site, and can be used in conjunction with various sensors and transmitters to achieve measurement, display, adjustment, alarm control, data acquisition, and recording of physical quantities such as temperature, pressure, liquid level, capacity, and force.
Intelligent digital display instrument with dual row or single four digitsLEDDisplay measurement values（PV）And the set value（SV）Analog display of measured value percentages using monochrome or two-color light columns, with zero and full correction, cold end compensation, digital filtering, communication interface, etc6Multiple alarm methods, optional1~4Relay alarm output, optional transmitter output, or standard communication interface（RS485perhapsRS232C）Output, etc.
