P331
Tank Level Transmitter
For Anderson, Cherry Burrell, or King Gage Receivers
Fast Thermal Response Time
Hasteloy C -276 available
Designed for sanitary markets
Tel-Tru's P331 is 3A compliant and designed for CIP/SIP
systems. Key feature of the sensing element is advanced
temperature compensation methods, which not only
improves performance over a wide temperature band,
but greatly reduces CIP/SIP recovery times.
Manufactured for CIP/SIP & Wash- down areas
The P331 is manufactured for reliability and stability
in high humidity environments, and where direct sprays
for wash-down purposes are present.
316L SST standard material of construction
The P331's construction of all 316L SST makes it an ideal
choice for applications involving aggressive fluids.
