WIKA SA-11 pressure transmitters meet 3A and EHEDG sanitary criteria for pressure and level measurement in the food, pharmaceutical, cosmetic and beverage industries. They feature 0.25% accuracy, rugged 316L SS wetted construction and a wide operating temperature range.

The SA-11 features an integral cooling extension between the Tri-Clamp® connection and transmitter body. This design increases the maximum permissible media temperature to 150°C (300°F).

The 316L SS flush diaphragm ensures a crevice free seal between the process connection and the pressure measuring diaphragm. The permanently sealed sensing system includes food grade (FDA approved) liquid fill and is designed for "clean in place" (CIP) and "sterilize in place" (SIP) maintenance procedures. The transmitters are available with industry standard 1.5" or 2" Tri-Clamp connections. They can be ordered with an optional NEMA 6P (IP 68) cable assembly for additional protection in wash down areas.
