Setra Systems Model 264

Differential Pressure Transducer

1.0 GENERAL INFORMATION

Every Model 264 has been tested and calibrated before shipment. Speciﬁc

performance speciﬁcations are shown on page 3 of this Guide.

Setra Systems 264 pressure transducers sense differential or gauge (static) pres-

sure and convert this pressure difference to a proportional high level analog

output for both unidirectional and bidirectional pressure ranges. Two standard

output versions are offered: A voltage output of 0 to 5 VDC or a current output

of 4 to 20 mA.

2.0 MECHANICAL INSTALLATION

2.1 Media Compatibility

Model 264 transducers are designed to be used with air or nonconducting

gases. Use with liquids or corrosive gases will damage the unit.

2.2 Environment

The operating temperature limits of the 264 are 0°F to +175°F (-18°C to +79°C).

The compensated temperature range is 0°F to +150°F (-18°C to +65°C).

2.3 Pressure Fittings

The Model 264 is designed to be used with 3/16” I.D. push-on tubing. Both the

positive (high) pressure port and the reference (low) pressure port are located

on the front of the unit, labeled “HIGH” and “LOW” respectively. For best

results (shortest response times), 3/16” I.D. tubing is suggested for tubing

lengths up to 100 feet long, 1/4” I.D. for tubing lengths up to 300 feet, and 3/8”

I.D. for tubing lengths up to 900 feet.

3.0 ELECTRICAL INSTALLATION

If the Model 264 is supplied with the optional Conduit Enclosure, access the

electrical terminations by removing the cover. The output of 0 to 5 VDC or

4 to 20 mA is designated by speciﬁc Code numbers in the conﬁgurable part

number; i.e., 2641xxxxx 11xx x, where 11 designates the 4 to 20 mA output;

2641xxxxx 2Dxx x, where 2D designates the 0 to 5 VDC output. The output is

also shown on the 264 label.

For CE Compliance, a shielded cable with both ends properly grounded is

required.

3.1 Voltage Output Units

The Model 264 voltage output is a 3-wire circuit, with three terminals

available for wiring. These terminals have the designation COM, EXC and OUT

(See Diagram 1). The power supply and signal references are commoned on

the circuit (See Diagram 2). The 264 voltage output can operate from 9-30 VDC

excitation. The 264 has a 0 - 5 VDC output.
