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 voltage output or a 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 compat-
ible with 17-4 PH stainless steel, 300 series stainless steel and, viton/silicone or
Buna-N "O"-RIngs. The optional 3-valve manifold assembly is designed to be
used with gases or liquids compatible with 360 Brass, Acetal plug valves and
Nitrite O-rings. Never totally submerge the unit in any liquid.

2.2 Environment

The operating temperature limits of the 230 are as follows:
Operating Temperature Range °F (C°)
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 manifold assembly is supplied with
1/4"–18 NPT internal fittings.

2.4 Moisture Precautions

The Model 230 is provided with two 0.875 DIA conduit openings for electrical
termination, intended for a 1/2" I.D. conduit connection. These openings must
be sealed according to standard industry practice, in order to prevent moisture
ingress into the Model 256.

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 location 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.
