The single-loop intelligent measurement and control instruments using dedicated integrated chip, measuring input and output with digital correction and self-calibration techniques, so the measurement is accurate and stable by eliminating the effects of temperature drift and time drift error. The instrument adopted a multi-protection and isolation optimization design, achieved the purpose of stronger anti-interference ability, higher reliability.
The single-loop intelligent measurement and control instrument’s hardware was greatly reduced, its composition is relatively simple,compatible with a variety of input signals (thermocouple / RTD / linear voltage / linear current / linear resistance, etc.).
By conjunction with variety of sensors, or transmitters, it can realize the measuring and control of temperature, pressure, level, length, capacity,force and other physical measurement, display and alarm control, so its application is very wide.
