Setra Model 227

Ultra High Purity 1 1/8’’ Down-Mount

“C” Seal and “W” Seal Pressure Transducer

1.0 GENERAL INFORMATION

Every Model 227 has been tested and calibrated before shipment. Model 227

performance specifications are listed on Page 6 of this Guide.

Setra Systems 227 pressure transducers measure 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 .

Note: These instructions are also available on our website 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.

2.0 MECHANICAL INSTALLATION

2.1 Media Compatibility

Model 227 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 227 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)

Operating temperature limits with Option N1 are as follows:

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 227 pressure transducers are supplied

with 1.125” 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.
