HART Protocol Intelligent Pressure Transmitter
Product Description:
SMP4031 series universal digital pressure transmitters use a Stainless
Steel insulation film silicon pressure sensor as a signal measurement components, and do zero and temperature
performance of wide temperature range by using the dedicated IC circuit on the transmitter. The product used in petroleum, chemical, metallurgical, power,
hydrological and other industrial processes on-site pressure
measurement.
