Pressure Sensors

Series 40 - Flanged


Series 40 Pressure Sensors are the industry standard for protecting instrumentation and pressure measurement of slurry and corrosive fluids. 

All sensors are isolated and protected from the process, assuring positive and accurate readings. The full-faced, through-bolted Series 40 installs directly in-line.


Series 42/742 - Threaded

Series 42 Pressure Sensor and Series 742 Diaphragm Seal isolate and provide accurate instrument reading of gauges, transmitters, and pressure switches, making them ideal for use in chemical or slurry service. 

They can be mounted in any flow direction, and have threaded ends manufactured to standard NPT pipetap dimensions for smaller pipelines.
