Model 231
Multi-Configurable, Wet-to-Wet
Differential Pressure Transducer
Setra’s 231 is a multi-configurable, wet-to-wet differential pres-
sure transducer offering the user an all-in-one device with field
selectable pressure ranges and analog outputs. The device is
offered with an optional 3 or 5 valve machined brass manifold
for ease of installation and maintenance. The 231 has a robust,
NEMA 4 enclosure with a hinged, captive cover allowing for
easy access to switches for adjusting the range and output. An
optional display is available that allows users to view high, low,
and differential pressure readings on a simple rotating cycle.
Field Selectable Pressure Ranges
The 231 offers 8 field selectable pressure ranges which can be
changed using a slide switch, reducing risk of installing the
wrong range unit. The multi-range functionality allows the
user to hold less inventory and add additional flexibility in the
field.
Quick & Simple Installation
The 231 provides the user with an optional 3 or 5 valve ma-
chined brass manifold which can save money on installation
and maintenance. The single piece construction of the brass
body has no internal process connections, eliminating the risk
of internal leaks.
Robust Enclosure for Difficult Applications
The 231 NEMA 4 housing offers an optional LCD display for in-
stant indication of the high, low and differential pressure read-
ings. A hinged enclosure makes it suitable for harsh environ-
ments and saves the hassle of misplacing it when completing
a difficult installation.
