Installation Guide
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
3.1 Voltage Output Units
The Model 209 voltage output is a 3-wire circuit. If the 209 is supplied with 2 feet of
cable, the electrical connection is as follows:
Red + Excitation

CAUTION: Unit is reverse excitation protected. However, do not apply power
to output lead as this could cause permanent damage.
3.2 Current Output Units
The Model 209 (current output) transducer is a true 2-wire, 4-20 mA current
output device and delivers rated current into any external load of 0-800 ohms.
The 4-20 mA units are designed to have current flow in one direction only PLEASE OBSERVE POLARITY. We suggest that the electrical cable shield be
connected to the system’s loop circuit ground to improve electrical noise
rejection. The electrical connection is as follows:

The 209 has a 2-wire cable, where red is positive and black is negative.
CAUTION: Reverse excitation will not cause damage to the unit unless voltage
applied is above 50 VDC. However, the unit will not function if reverse wired.

3.6 EMC Certification
This product complies with EN61326 Electrical Equipment for Measurement, Control and
Laboratory use – EMC Requirements for Minimum Requirements and Industrial Locations.
Special caution should be taken to meet Standard EN61000-4-5: 1995 Surge Immunity if
any of the following conditions apply to the installation: The product is installed outside;
all or any part of the cable is exposed to the outside; the cable is greater than 30 meters in
length. In order to meet the Surge Immunity requirements, the following conditions must
be followed during installation:
1. Sh i elded cable must be used, and the shield must be tied to earth ground (not power supply
ground) on at least one end of the cable shield/drain wire. The shield must be maintained all
the way from sensor to the power supply.
2. If u nsh ielded cable is used, an earth grounded metal conduit fitting can be used to replace the
shielded cable.
3. Fo r a s enso r with a metal body or enclosure, the body/enclosure must be grounded to earth. If
a protective metal housing is used, the metal housing should be grounded to earth
4. If a protective plastic housing is used, the housing must be able to withstand at least
