The PZ3000-GP/AP type intelligent gauge pressure/absolute pressure transmitter adopts advanced monocrystalline silicon piezoresistive technology. The product is used to measure the liquid level, density and pressure of liquids, gases or vapors, and then convert the pressure signal into a 4mA~20mA DC analog current signal for output. At the same time, remote setting, monitoring and other functions can be realized through communication equipment. It is suitable for harsh process industrial fields.
