Setra System Model 217 - Manual (Page 2)

Setra Model 217
Ultra High Purity Flow-Through Pressure Transducer
1.0 GENERAL INFORMATION
Every Model 217 has been tested and calibrated before shipment. Performance
specifications are listed on Page 6 of this guide.
Setra Systems 217 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 a current output of 4 to 20 mA FSO .
Note: These instructions are also available on our website at www.setra.com.
1.1 EMC Certification
This product complies with EN61326-2-3:2006 and EN61326-1:2006 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 prod-
uct 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.
2.0 MECHANICAL INSTALLATION
2.1 Media Compatibility
Model 217 transducers are designed to be used with any gas or liquid compat-ible with 316L Stainless Steel. Never
submerge the transducers in any liquid.
2.2 Environment
The operating temperature limits of the 217 are as follows:
Operating Temperature Range°F (°C) -40 to +185 (-40 to +85)
Compensated Temperature Range°F (°C) +15 to +150 (-9 to +65)
Current unit ordered with Option N1:
Operating Temperature Range°F (°C) -22 to +176 (-30 to +80)
Compensated Temperature Range°F (°C) +15 to +150 (-9 to +65)
2.3 Pressure Fittings
Mounting - Model 217 pressure transducers are supplied with
1.5” down-mount “C” or “W” seal base. (Note: The
torque values listed are typical for most systems, please adjust the values to fit your system.)
The tightening sequence forms a leak tight seal between the base block and the unit. Using
4 screws to install the unit, follow the torque sequence pattern in Diagram 1. Use a torque
driver and torque all 4 screws to 25 in. lbs, repeat sequence and torque all 4 screws to
35 in. lbs, then repeat sequence for 45 in. lbs.
2.4 Venting
Model 217 transducers are vented through the electronic housing.
