Modell SET-290
|
The 290 design meets 3-A sanitary design standards and is fully sealed to withstand external high pressure washdown and CIP/SIP cycles. As a totally self-contained electronic package, the 290’s capacitance sensing element, coupled with a signal conditioned IC-based circuit, assures excellent accuracy and long term stability.
The 290 pressure transmitter is intended for low to high pressure measurements of gases or liquids in sanitary applications. The 290 pressure transmitter, packaged in a rugged welded stainless steel housing, is exceptionally insensitive to vibration, shock and environmental extremes. Its small size, light weight, and tri-clover sanitary pressure fitting allows direct mounting in most CIP and SIP installations.
Unlike fluid-filled sensors, the 290 utilizes a rugged, non-filled capacitive sensor which enables low hysteresis and excellent performance during thermal transients.

---|---|---|---|
[1] | RSS of Non-Linearity, Non-Repeatability and Hysteresis. | ||
[2] | Units calibrated at nominal 70°F. Maximum thermal error is computed from this datum. Variations in the power supply voltage cause less than 0.005 mA change in the transmitter’s current output, per volt change in the power supply. Reverse excitation will not damage circuit. | ||
[3] | Calibrated at factory with a 24 VDC loop supply voltage and a 250 ohm load. | ||
[4] | Zero output factory set to within ±0.08mA. Span (Full Scale) output factory set to within ±0.16mA. | ||
[5] | Operating temperature limits of the electronics only. Pressure media temperatures may be considerably higher or lower. | ||
