P321
Sanitary Pressure Transmitter
Precision Grade Tri-Clamp or Cherry-Burrell Fittings
Designed for the sanitary markets
Tel-Tru’s P321 Series is designed for the OEM and end user where
ruggedness, high performance, and reliability are required at a
competitive price. Key feature of the all welded sensing element is its
isolation from induced stresses. This results in negligible zero and span
offsets due to the installation clamping force effects. This product is
modular and is congurable to meet our customers’ exact needs.
For CIP and Wash-Down Areas
Manufactured for reliability in clean-in-place and wash-down areas
The P321 is built using advanced manufacturing techniques, with
automated welding procedures, extreme environmental burn-in and
thorough residual stress relieving techniques. The P321 NEMA 4X
packaging ensures reliable service in the wash-down environments of
the sanitary industry regardless of signal output or pressure format.
“Backed-up” sensing diaphragm
Every P321 sensing diaphragm is “backed-up” with a solid piece of
stainless steel which greatly improves the resistance to sharp objects
and overpressure.
Certication
Every P321 is shipped with a NIST traceable calibration certicate.
