Senex DG1300-GW High Temperature Pressure Transmitter
DG1300-GW
Designed for demanding industrial environments, the Senex DG1300-GW High Temperature Pressure Transmitter delivers high-accuracy 4-20mA pressure measurement for elevated temperature media such as steam and thermal oil, utilizing a robust fully-welded stainless steel construction and advanced piezoresistive sensing technology to ensure long-term stability and superior resistance to thermal drift and RF interference.
The Senex DG1300-GW High Temperature Pressure Transmitter is engineered specifically to measure liquid, gas, or steam pressure in high-temperature operating environments up to 150°C. Powered by an advanced piezoresistive sensor core integrated with a high-reliability amplification circuit and precision temperature compensation, this transmitter converts process pressure into an industry-standard 2-wire 4-20mA DC current loop output. Its compact, fully-welded stainless steel structure eliminates internal sealing rings, offering outstanding resistance to shock, vibration, and lightning strikes while meeting IP65 ingress protection standards. Manufactured with precision thermal drift control, the DG1300-GW ensures zero and span stability, high sensitivity, and precise performance in severe process applications including steam boilers, thermal oil lines, and power generation inspection systems.
