1.0 General Information

Every Model 206 has been tested and calibrated before shipment.

Performance specications are shown on page X of this guide.

Setra Systems Model 206 pressure transducers sense gauge and vacuum

pressure and convert this pressure dierence to a proportional high level

analog output. Two standard output and excitation versions are oered:

Excitation Output

9 to 30 VDC 4 to 20 mA (must observe polarity)

12 to 28 VDC 0.1 to 5.1 VDC (reverse wire protection up to 22VDC

excitation to the output lead

2.0 Mechanical Installation

2.1 Media Compatibility

Model 206 transducers are designed to be used with any gases or liquids

compatible with 17-4 PH stainless steel.

2.2 Environment

The operation temperature limits of the 206 are -40° to +260°F (-40 to

+127°C).

The compensated temperature range is -4 to +176°F (-20 to +80°C).

2.3 Pressure Fittings

Typically, standard pipe ttings and procedures should be used. However,

for pressure ranges in excess of 500 PSIG (35 Bar) we suggest the use of a

sealant such as Loctite Hydraulic Sealant. Excessive torqueing of metal t-

tings may cause a slight zero shit. The use of plastic ttings typically results

in no noticeable zero shift. Torquing does not appreciably aect linearity or

sensitivity.

2.4 Venting

The reference pressure in a sealed gage transducer will vary due to changes

in temperature, atmospheric pressure, humidity, etc. This change aects

the overall accuracy of the unit. To compensate all gage and compound

206 units are vented to atmosphere using the following methods based on

the electrical termination used.

6.0 Warranty & Limitation of Liability

Unless otherwise specied in a manual or warranty card, or agreed to in writ-

ing and signed by a SETRA ocer, SETRA pressure and acceleration products

shall be warranted for one year from date of sale.

The foregoing warranty is in lieu of all warranties, express, implied or statu-
