Setra 230 Specifications

Model 230

True Wet-to-Wet Differential

Pressure Transducer

The Model 230 is Setra’s highest accuracy solution for monitoring
dierential pressure in wet-to-wet applications. Its single diaphragm
design enables a true wet-to-wet dierential pressure measurement
with superior ±0.25% FS accuracy compared to competitive units
which calculate dierential 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 oered 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 a true wet-to-wet sensor with a
single diaphragm construction. The dierential pressure range of a
single diaphragm is not impacted by line pressure whereas dual dif­ferential pressure sensors require the individual sensors to measure
gauge pressure, comparing the outputs to determine the dierential
pressure.

Increase the Sensors Response Time

The 230 utilizes an all stainless steel capacitive sensor which responds
20x faster than oil lled sensors and provides conditioned electronic
circuitry with a highly accurate, linear analog output proportional to
the pressure over a wide temperature range.

Save Time on Money & Installation

When time and project costs are a priority, the 230 is oered 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.
