Calectro CPS-D-SW

CPS-D-SW

CPS-D-SW is designed for monitoring differential pressure in ventilation systems.

Pressure switch CPS-D-SW has an integrated differential pressure element that is temperature-compensated for high accuracy and linearity. The pressure element has high resolution, which means that the pressure value is presented in increments of max 1 Pa over the entire measurement range (0-3500 Pa).

The required function and range is set on a backlit display. The relay output can be set to activate when the pressure is above or below the setpoint. You can also choose whether the relay output should close or break open activation. The damping of the measured value is selectable in three modes: 3, 10 and 20 seconds averaging. Setting of hysteresis and zero calibration of the pressure element is also carried out on the display.

In the display’s basic mode, the current measured value, setpoint and the relay’s current mode (closed or opened) are displayed. If the relay is activated, the display’s backlight blinks and HIGH PR. or LOW PR. is displayed depending on the current setting.

CPS-D-SW is factory-set as an overpressure switch with a setpoint of 300 Pa. The relay is in N.O. mode (normally open) when the pressure is below the setpoint) and the averaged damping is set at 3 seconds.

The terminal block and enclosure cable port (with a pre-mounted M16 cable gland) are removable for easier installation. The enclosure cover is hinged at the top, has a snap fastener at the bottom and catches to keep the cover in raised position.

CPS-D-SW is wall-mounted with the hose connectors pointing downwards.
Delivered with 2 m hose and 2 nipples.
