intelligencetransmitterCircuit functions and advantagesThe circuit shown in Figure 1 is a robust and flexible loop supply currenttransmitterThe differential voltage output of the pressure sensor can be converted into a current output of 4 mA to 20 mA. This design is optimized for various bridge voltage or current driven pressure sensors, using only 4 active devices with a total unadjustable error of less than 1%. looppower supply
The voltage range is 12V to 36V. The input of this circuit hasESDThe protection function and the ability to provide voltage protection above the power rail are ideal choices for industrial applications.Figure 1. Robust Loop Power Supply Pressure
