Series 42/742- Chemical/Slurry Pressure Sensor |
| |
REOTEMP Series 42/742 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.

The Series 42 and Series 742 can be mounted in any flow direction,
and have threaded ends manufactured to standard NPT pipetap dimensions
for smaller pipelines. The principle of operation is simple. As process
pressure is sensed by the 360° elastomer sleeve, the captive fluid
transfers the process pressure to the instrument, providing a
consistent, accurate reading.
The Series 742 offers a significant advantage over traditional
diaphragm seals. When installed perpendicular to the pipeline, the
Series 742 can be isolated so that in the event of plugging, the
elastomer slurry ring area, which isolates the instrument, can be
flushed or rodded clean.
Series 42 Pressure Sensors and Series 742 Diaphragm Seals are
available in sizes ½” through 2”. The Series 42 features a tip-mounted
gauge, while the Series 742 is supplied with a standard back mounted
gauge. A complete Series 742 Diaphragm Seal, including optional
isolation ball valve, is available for immediate delivery.
