Digital stainless steel room pressure monitor
± 1/0.5/0.25%, 4 - 20 mA, 24 - 240 VAC/VDC, IP65, SPDT, OLED Sensocon, Inc.

The Series CR is a microprocessor based room pressure monitor for positive, negative, and differential pressure. The Series CR has a 316L Stainless Steel cover to meet clean room and other high purity and wash down requirements. It features (2) 8A SPDT relays for control and a 4-20 mA output.

The programmable control allows full configuration of variables such as setpoints, dead band, engineering units, flow coefficients, and more. The programming is done with a user-friendly Opti-LinkTM remote on the OLED display or uploaded using an Opti-LinkTM programming key. The OLED also displays the exact setpoints or other user defined variables during normal operation. Furthermore, the menu structure can be customized by moving variables to different menu levels to accommodate many applications.
