OPERATING INSTRUCTIONS
SANITARY PRESSURE TRANSMITTERS

GENERAL INFORMATION

Your Setra C290 Sanitary Pressure Transmitter has been carefully tested and calibrated be-
fore shipment and it should be handled with the same care given any precision instrument.
Detailed performance information is listed on the specification bulletin for the transmitter.
The C290 is designed according to 3A Standard, as indicated on etched cover label, for sanitary
installations. It has a rugged MICRO-TIG welded stainless steel housing and is exceptionally in-
sensitive to vibration, shock, EMI/RFI interference and other environmental extremes. The C290
is insensitive to the thermal shocks typical of CIP and SIP installations.

INSTALLATION NOTES

Model C290's should not require adjustment at installation. If adjustments are made it
is important to replace and tighten the zero and span screws (with O-rings) to
prevent moisture from entering.
The C290 is vented through the cable. Connections to the cable should be made in a
dry junction box vented to atmosphere. Insure that moisture cannot enter the end of the
cable.
The C290 is shipped with a rubber boot over the stainless steel pressure sensing
diaphragm to protect the diaphragm during shipment, storage, and handling prior to
installation. This boot should not be removed until the transmitter is to be installed and
should be used whenever the unit is removed from its installation. Do not contact the
diaphragm with sharp objects, screwdrivers or other mechanical devices.
Environment - The C290 Transmitter is designed to be used with any gas or liquid
compatible with 316L stainless steel (316 for ranges > 30 psig). It is designed to be
splash and drip proof for wash-down cleaning and can also be completely submerged
with the exception of the open end of the electrical cable.
Cleaning - The pressure sensing diaphragm will withstand normal high pressure
washing and partial vacuums created by fast cooling of steam sterilized tanks. However,
be sure not to exceed the proof pressure (listed on specification sheet). In high pressure
washing, care should be taken not to spray directly on diaphragm as it could result in
exceeding the proof pressure. The C290 can also be cleaned by dipping the diaphragm
in a container of cleaning solution or by wiping gently with a soft cloth.
Temperature Limits - The operating temperature limits of the C290, based on the limits
of the electronics, are -40 o F to 260 o F.
Thermal Effects
Zero Shift
Span Shift
Mounting - The C290 will mount directly to a mating tri-clover flange along with a tri-clover
type clamp and gasket. (2 inch tri-clover for ranges up to 30 psig and 1.5 inch for higher ranges.)
Horizontal mounting is recommended to enable proper cleaning and draining of liquids from
sensor cavity.
Note: The output signal is not appreciably affected by clamping forces so it is not necessary to
orient the flange circle to any special position for best performance.
