Model 230 Low Differential Pressure Transducer
Brand: Setra Systems, IncThe 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% Full Scale accuracy compared to competitive units which calculate differential pressure using two single point pressure sensors.
The stainless steel capacitive sensor provides a highly accurate, linear Analog output proportional to the 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.
Features- No liquid fill diaphragm
- Low line pressure effect
- Fast response time
- Gas and liquid compatible
