Gauge pressure

image of Model A105 Flush Diaphragm Pressure Transducer

The RDP model SPT-A105 sensor measures the pressure of a compatible fluid or gas.
The SPT-A105 gauge pressure transducer measures with respect to atmospheric pressure.
This transducer has a flush diaphragm so there are no cavities for sediment to collect or for material to solidify.
