The Model 230 is Setra’s highest accuracy solution for monitoring differential pressure in wet-to-wet applications.  Its single diaphragm design enables a true wet-to-wet differential pressure measurement with superior ±0.25% FS accuracy compared to competitive units which calculate differential pressure using two separate point pressure sensors.  The stainless steel capacitive sensor provides a highly accurate, a linear analog output proportional to pressure over a wide temperature range.  The 230 is offered with an optional 3 or 5 valve machined brass manifold for ease of installation and maintenance.

Avoid Line Pressure w/ Single Diaphragm Sensor – Unlike the competition, the 230 is an accurate wet-to-wet sensor with a single diaphragm construction.  Line pressure does not impact the differential pressure range of a single diaphragm whereas dual differential pressure sensors require the individual sensors to measure gauge pressure, comparing the outputs to determine the differential pressure.

Increase the Sensors Response Time – The 230 utilizes an all stainless steel capacitive sensor which response 20x faster than the oil filled sensor and provides conditioned electronic circuitry with a highly accurate, linear analog output proportional to the pressure over a wide temperature range.

Save Time & Money on Installation – When time and project costs are a priority, the 230 is offered with an optional 3 or 5 valve machined brass manifold for ease of installation and maintenance.  The brass body has no internal process connections, therefore eliminating the risk of internal leaks.
