890 Series - 3A Sanitary Pressure Transducer For Clean-In-Place (CIP) and Sterilize-In-Place (SIP) 0.20% Full Scale Accuracy No Liquid Fill Diaphragms The 890 Series meets 3A sanitary design standards and is fully sealed to withstand external high pressure washdowns. These units are packaged in rugged welded stainless steel housings and are exceptionally insensitive to vibration, shock and environmental extremes. A small size and tri-clover sanitary pressure fitting allow direct mounting in most CIP and SIP installations. Other features include IC-based circuitry, a 1/2 " NPT conduit fitting and shielded cable with vent tube. Sealed screws provide access to zero and span adjustments.

Pressure on the diaphragm alters the sensor's capacitance, which is then detected and converted to a highly accurate linear 4-20 mA signal by electronic circuitry featuring Gems' patented charge-balance principle. Low hysteresis, very stable operation and negligible clamping effect are inherent. Visit www.GemsSensors.com for most current information. 890 Series / p1of2 / 9-JUL-19http://www.GemsSensors.com
