Setra 290 Data Sheet

Model 290

Sanitary Pressure Transducer

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 lled 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
eect 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
certication 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 eect and ther­mal transients when compared to liquid lled sensors. The
diaphragm is able to withstand pressure down to full vacu­um for worry free operation during tank and piping evacu­ation cycles.

Model 290 Features:

Negligible Clamping Effect

The process interface of the 290 negates the eect 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; its optional 20Ra nish make it the ideal
solution for use in Biotech applications.
