PMA Process Machinery Automation Pressure Transmitters are designed for pressure measurement applications where a compact size sensor is required for ease of installation. The body construction features a stainless steel housing, diaphragm and process coupling. There are several choices for process connections either flush fitting or manometer threaded connection. In addition for pulsing pressure measurements, mechanical damping is available for all the P Series Transmitters. The factory automation P Series models have measurement spans selections from 0-0.25 to 0-400 Bar absolute or gauge pressure. They also feature permissible overload ratings of four times the span. Transmitter outputs are voltage or current in two or three wire versions with low power requirements of 12-30 VDC. The PMA process control P Series Pressure Transmitters primary measurement sensor is constructed from a low-mass Silicon Strain Gauge that ensures long-term stability and typical low 0.3% linearity error. Process control media can be any clean liquid or gas compatible with the wetted parts and electrical safety requirements of the transmitter.
