Setra Model 230
Wet/Wet Differential Pressure Transducer
1.0 GENERAL INFORMATION
Every Model 230 has been tested and calibrated before shipment. Setra Systems 230 pressure transducers sense differential
pressure and convert this difference in pressure to a proportional high level analog output. The 230 is supplied with either a
0 to 5 VDC or 0 to 10 VDC output or current output of 4 to 20 mA.
2.0 MECHANICAL INSTALLATION
2.1 media compatibility
Model 230 transducers are designed to be used with any gas or liquid compatible with 17-4 PH stainless steel, 300 series
stainless steel, and viton/silicone or Buna-n “O”-Rings. The optional 3-valve or 5-Valve manifold assembly is designed to be
used with gases or liquids compatible with 360 Brass, Acetal plug valves and Nitrile O-rings. Never totally submerge unit in
any liquids.
2.2 environment
The operating temperature limits of the 230 are as follows:
Operating Temperature Range °F (°C) 0 to +175 (-18 to +80)
Compensated Temperature Range °F (°C) +30 to +150 (-1 to +65)
2.3 Pressure fittings
Typically, standard pipe fittings and installation procedures should be used. The Model 230 has 1/4”-18 NPT internal fittings.
The high pressure port is labeled “HIGH”. The optional 3-valve and 5-valve manifold assembly is supplied with 1/4”-18 NPT
internal fittings.
2.4 moisture Precautions
The Model 230 is provided with a 0.875 DIA. conduit opening for electrical termination, intended for a 1/2” I.D. conduit con-
nection. This opening must be sealed according to standard industry practice in order to prevent moisture ingress into the
Model 230.
2.5 mounting
The Model 230 is supplied with a mounting bracket and two 6-32 x 3/8 hex head screws. Attach bracket to mounting loca-
tion first, using holes or band clamp notches available on large section of the bracket. Attach transducer to bracket by using
the two 6-32 x 3/8 hex head screws and the two tapped holes located on the underside of the transducer.
