Setra Systems Model 209

Pressure Transducer

1.0 GENERAL INFORMATION

Every Model 209 has been tested and calibrated before shipment.

Setra Systems 209 pressure transducers sense gauge pressure and convert this

pressure difference to a proportional high level analog output. Three standard

output and excitation versions are offered:

Excitation Output

9 to 28 VDC 4 to 20 mA - (Must Observe Polarity)

9 to 30 VDC 0.5 to 5.5 VDC - (Reverse excitation protection)

4.9 to 8.1 VDC 0.5 to 4.5 VDC - (No reverse wire protection)

2.0 MECHANICAL INSTALLATION

2.1 Media Compatibility

Model 209 transducers are designed to be used with any gases or liquids

compatible with 17-4 PH Stainless Steel.

2.2 Environment

The operating temperature limits of the 209 are -40° to +185°F (-40 to +85°C).

The compensated temperature range is -4 to +176°F (-20 to +80°C).

2.3 Pressure Fittings

Typically, standard pipe fittings and procedures should be used. However, for

pressure ranges in excess of 500 psig, we suggest the use of a sealant such as

Loctite Hydraulic Sealant. Excessive torquing of metal fittings may cause a

slight zero shift. The use of plastic fittings typically results in no noticeable zero

shift. Torquing does not appreciably affect linearity or sensitivity.

2.4 Tube Stub Welding Instructions

Standard welding practices should be followed. Caution must be taken to

protect the sensor against current paths that could damage the circuit board.

Apply a heat sink between the weld zone and the sensor that is large enough

to protect the sensor from overheating. Failure to use a heat sink may damage

the housing seal or circuit board.

2.5 Venting

Because the reference pressure in a sealed gage transducer will vary due to

changes in temperature and will affect overall accuracy (especially in units of

less than 500 psig range), all 209 Series transducers are available as vented or

sealed to atmosphere.

Vented units are ordered as PSIG range units. Sealed units are ordered as PSIS

range units. The 209 PSIG transducers are vented through the cable.

Hirschmann PSIG transducers are vented through the connector. Packard

PSIG units are vented through a porous filter plug supplied on the unit.

3.0 ELECTRICAL INSTALLATION

The Model 209 is available in four electrical terminations:

2 foot Cable Hirschmann Connector

Packard Connector Conduit Adapter, 1/2 inch
