Diaphragm pressure switch 290

absolutefor airfor hygienic applications

The Model 290 is Setra’s highest accuracy solution for measuring gauge and compound pressure ranges in sanitary processing applications. Unlike competitive transducers which use an oil filled design, the 316L stainless steel sensor is designed to operate without the need for an intermediary liquid within the sensor. The design of the 290 negates clamp effect making installation and service faster and easier than the competition. Its small footprint and accuracy (±0.2% FS) covers a wide range of pressure ranges that meet both 3A certification and withstand CIP/SIP environmental conditions, making it ideal for a variety of applications. Robust Non-Liquid Filled Sensor - The Model 290 sanitary pressure transducer uses an air variable capacitance sensor. This sensor design eliminates chance of “product” contamination, position effect and thermal transients when compared to liquid filled sensors. The diaphragm is able to withstand pressure down to full vacuum for worry free operation during tank and piping evacuation cycles. Negligible Clamping Effect - The process interface of the 290 negates the effect of clamping pressure on the output signal of the sensor. This design allows the sensor to be delivered in a small footprint with the diaphragm closely mounted to the process media which ensures the most accurate measurements. Flexibility in Application - The Model 290 is the most versatile sanitary pressure transducer on the market. Its design allows full scale tank level measurements as low as 27.7” WC with an accuracy of 0.027” and up to 1000 PSI for process lines. The 316L wetted components meet 3A requirements for food and beverage industry applications
