This series of intelligent digital display instrument adopts a dedicated integrated instrument chip, and the measurement input and transmission output adopts digital correction and self-calibration technology, the measurement is accurate and stable, and the measurement error caused by temperature drift and time drift is eliminated. This series of instruments adopts surface mount technology, and has designed multiple protection and isolation designs, and has passed the EMC electromagnetic compatibility test. It has strong anti-interference ability, high reliability and high cost performance.
This series of intelligent digital display instruments have multi-type input programmable functions. One instrument can be connected to different input signals (thermocouple/thermal resistance/linear voltage/linear current/linear resistance/frequency, etc.), and at the same time display range, alarm control It can be set by the user on-site, and can be used in conjunction with various sensors and transmitters to realize the measurement display, adjustment, alarm control, data acquisition and recording of physical quantities such as temperature, pressure, liquid level, capacity, force, etc. widely.
The intelligent digital display instrument displays the measured value (PV) and set value (SV) with double or single-row four-digit LED, and the analog display of the measured value percentage with single-color or double-color light bar, and also has zero and full scale correction, cold Terminal compensation, digital filtering, communication interface, 4 alarm modes, optional 1 to 4 relay alarm outputs, optional transmission output, or standard communication interface (RS485 or RS232C) output, etc.
