Setra System Setra Model 206 - Manual (Page 2)

1.0 General Information
Every Model 206 has been tested and calibrated before shipment.
Performance specifications are shown on page X of this guide.
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 +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 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 fit-
tings may cause a slight zero shit. 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.
6.0 Warranty & Limitation of Liability
SETRA warrants its products to be free from defects in materials and work-
manship, subject to the following terms and conditions: Without charge,
SETRA will repair or replace products found to be defective in materials or

e) SETRA is notified in advance of and the product is returned to SETRA
transportation prepaid.
Unless otherwise specified in a manual or warranty card, or agreed to in writ-
ing and signed by a SETRA officer, 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-
tory, including but not limited to, any implied warranty of merchantability for
a particular purpose.
SETRA’s liability for breach of warranty is limited to repair or replacement, or
