Sanitary Pressure Transmitter- Series 637s
Meets NACE and 3A Sanitary Standards; Accuracy ±0.25%
Low cost, durable sanitary pressure transmitter is designed to meet 3A standards allowing use in food, dairy, beverage and pharmaceutical industries. This unit features superior ± 0.25% accuracy and 5:1 turndown. Calibration is quick and easy with field accessible zero and span adjustments. All stainless steel construction resists the corrosive effects of caustic washes used in most food processing cleaning procedures. 1 ½" Tri-Clover process connection is suitable for Clean-in-Place (CIP) applications, eliminating the need for expensive bypass piping, valving or removal requirements for steam cleaning.
