Setra Model GCT225
Ultra High Purity Transducers
1.0 GENERAL INFORMATION
Your Setra Pressure Transducer has been carefully tested and calibrated before
shipment. Model GCT225 performance specifications are listed on page 6 of
this Guide.
Setra Systems GCT225 pressure transducers sense gauge, compound, or
absolute pressure and convert this pressure to a proportional high level analog
output. Two output versions are offered: A voltage output of 5 VDC FSO (Full
Scale Output) and 10 VDC FSO, and current output of 4 to 20 mA
Note: These instructions are also available on our web site at www.setra.com.
1.1 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. Shielded 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 unshielded cable is used, an earth grounded metal conduit fitting can be used to
replace the shielded cable.
3. For a sensor 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
2 KV from the housing to earth ground, without damaging the circuit.
