4-20mA Remote Pressure Sensor Working

This 4-20mA Remote Pressure Sensor Working is a sensor that responds to measured variables through a sensing element and converts it into a standardized transmission signal (eg 4-20 mA), which is only a function of the measured variable. It provides more than 20mA of current to the loop supply in the general purpose PLC / DCS analog input card channel. It has a built-in voltage regulator function to regulate the loop current.

Product description:

This 4-20mA Remote Pressure Sensor Working is a sensor that responds to measured variables through a sensing element and converts it into a standardized transmission signal (eg 4-20 mA), which is only a function of the measured variable. It provides more than 20mA of current to the loop supply in the general purpose PLC / DCS analog input card channel. It has a built-in voltage regulator function to regulate the loop current. It will configure other details of LRV, URV and process variables. The transmitter can change the loop current based on the measured process variable. It minimizes the amount of wires needed to run power and signals. 4-20mA Remote Pressure Sensor Working uses a current loop to transmit signals and also has the effect of reducing the sensitivity to electrical noise and load effects. It is very common in industrial control and automation. It requires only two analog signal lines to monitor remote processes. The two wires carry both the power and analog output signals of the sensor or supervisory circuit. 4-20mA Remote Pressure Sensor Working's resistance sensor is placed in a full resistance bridge. The output of the bridge is connected to the instrumentation amplifier INA, which provides gain and level shifting of the sensor output.
