Four Wire High Accuracy Pressure Transmitter 4-20ma

NP-3051 Pressure Sensor Transmitter

NP3051 series intelligent differential pressure / pressure transmitter is an intelligent field instrument in accordance with HART protocol. The original imported diaphragm is designed with a microprocessor and a HART communication circuit. It can communicate bidirectional with any host computer software supporting HART communication protocol or 268,275 hand-operated devices that conform to HART communication protocoL With 5 bits intelligent digital liquid crystal display, the differential pressure / pressure value, output current value and output percentage value can be displayed on the spot. The debugging is very convenient, and the digital and intelligent functions of the transmitter are realized. And with the traditional 4〜20mA simulation input The output signal is compatible so that the exchange with the analog table can be achieved without changing the control system.
