1、 Product application

The HCS4333 differential pressure absolute pressure transmitter is a digital instrument with good user interface and high accuracy. Parameter settings can be made through control keys, HART communication, PROFIBUS PA, or the Foundation's on-site main interface Transmitters that meet the requirements of 'intrinsic safety' and 'explosion-proof' can be installed in potentially explosive atmospheres (Zone 1) or (Zone 0). The HCS4333 differential pressure absolute pressure transmitter can be used in industrial fields with extreme chemical and mechanical loads. The electromagnetic compatibility within the range of 10KHz to 1GHz makes the HCS4333 differential pressure absolute pressure transmitter suitable for high electromagnetic radiation applications. Different models of series transmitters can be used to measure: gauge pressure, absolute pressure, differential pressure, liquid level, and flow rate.
