HWPB1 Universal silicon pressure transmitter is a high stability silicon piezoresistive pressure transmitter with isolation and precision compensation. The temperature compensation and zero deviation correction of the pressure sensitive element are made through the precision modified thick film circuit. The measured pressure is transferred to the silicon piezoresistive sensor through the 316L isolation diaphragm and the internal medium, which realizes the accurate conversion of pressure to electrical signal. The pressure transmitter program is very flexible, with an output signal of 4-20mA, available in absolute or relative (gauge pressure) versions, and the measurement range is from 0-1 to 0-1000 bar. The HWPB1 pressure transmitter incorporates all the latest technologies available in the field of electronic pressure measurement today, and has been developed over a long period of more than 10 years. The sensor adopts fully automatic linear and temperature compensation technology to ensure the efficiency and quality of mass manufacturing. The fully welded process and independent ventilated cavity structure ensure the long-term reliability of the product. The signal transmitter module adopts the original calibration technology and easily realizes the parameter setting without any tools.
