General Information and Installation
Your Setra transducer has been carefully calibrated before shipment to you, and it should
be handled with the same care given any precision instrument. Pressure range and
dimensions are reported on the applicable specifications bulletin.
Ambient Conditions
Do not submerge in liquids, use in ambient conditions corrosive to anodized aluminum,
subject to spray or dripping, or use in a high vibration environment. The transducer is
very slightly sensitive to acceleration in the pressure fitting axis (see applicable specifica-
tions bulletin for acceleration response specifications). Installation is recommended in
the vertical position, with the pressure port downward. This position minimizes damage
from drippage of pressure system piping.

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.
