1.0 General Information
Every Model 206 has been tested and calibrated before shipment. Setra Systems Model 206
pressure transducers sense gauge and vacuum pressure and convert this pressure difference to
a proportional high level analog output. Two standard output and excitation versions are offered:
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 +185°F (-40 to +85°C).
The compensated temperature range is -4 to +176°F (-20 to +80°C).
2.3 Pressure Fittings
Typically, standard pipe fittings 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 fittings may
cause a slight zero shift. The use of plastic fittings typically results in no noticeable zero shift.
Torquing does not appreciably affect 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 affects 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.
