DP-001 – digital pressure switch for relative pressure

The DP-0 pressure sensor series for measuring air pressure includes several electronic switches for which various switching parameters and functions can be set using buttons and values easily read out from a display.

The two-level setting mode permits simple configuration. The threshold value, offset and key lock/release parameters can be set in RUN mode. In DETAILED SETTING MODE the following functions can be selected: EASY, hysteresis and window comparator mode. Open/close functions, response time, display color and the physical unit of the measured pressure can also be set.

The miniaturized pressure switches measure relative pressure and are designed for indoor applications. They are calibrated and compensated for within a range of 0 to +50°C. DP-0 pressure switches come in a compact package with a large LCD. Installation is simple thanks to a wide range of accessories.

These digital pressure switches are available in the following versions:

DP-001-P: low-pressure switch, -1 to +1 bar, relative, PNP output, 50 mA, M5 female thread

DP-002-P: high-pressure switch, 0 to 10 bar, relative, PNP output, 50 mA, M5 pressure connector

The switches are also available as an NPN version on request.
