Setra System Model 567 - Manual (Page 5)

High Temperature Pressure Measurement : Possible using a length of piping or a "syphon" to
isolate the instrument from the hot media. Since there is no flow, the temperature drop along the tubing
is considerable and usually a relatively short length is sufficient to bring the pressure media temperature
within acceptable limits for the instrument. Alternatively a temperature isolator, part number GA33, can
be fitted (G¼ connection only). Pressure media must not be allowed to solidify in the tube and/or
pressure port.
ELECTRICAL INSTALLATION
All types include suppression devices providing transient protection to EN 61000-4-2 and EN 61000-
4-4.
For all types conformity with the requirements of the CE mark only applies when
connection is made with Setra Systems approved cable, See APPROVED CABLE
section, and the shield of that cable is connected to a reliable grounding point at the
instrumentation end.
APPROVED CABLES
Setra Systems uses cable comprising 7 color-coded wires, with a central vent tube, enclosed by an
aluminium/polyester shield where the shield is in contact with a separate drain wire. The outer shield
material is Polyurethane (immersible, +70°C). Other shield materials available on request for harsh
environments.
OPERATION
Having installed the transducer as instructed it is ready for use. The transducer should not be removed
whilst the system is at pressure. Before applying power, check that the correct polarity and excitation
levels are being applied. See ELECTRICAL REQUIREMENTS.
OPERABLE TEMPERATURE RANGE
Cable Versions: -4°F to +122°F (-20°C to +50°C)
Connector Versions: -4°F to +185°F (-20°C to +85°C)
Process Media (connector version only): -22°F to +212°F (-30°C to +100°C)
OPERATIONAL LIFE
Limited to 3 million full scale cycles.
CALIBRATION
Transducers are calibrated to the datum requested at time of order as follows:
G - gauge datum vented to atmosphere via the electrical connection
A - absolute datum
