Krohne introduced the OPTIBAR PSM 1010 and OPTIBAR PSM 2010 ultra-compact pressure switches for absolute and gauge pressure measurement in gasses and liquids, and is for use in the food and beverage industry. The switches feature configurable PNP/NPN switching output with IO-Link connectivity and a two-axis (multi-rotatable) LED display and adjustment module.

Both devices aim at basic automation applications such as hydrostatic level measurement in open tanks, dry-run protection of delivery pumps or pressure monitoring of compressors, hydraulic and pneumatic systems.

The switches feature a 2-axis (multi-rotatable) display and adjustment module, a robust construction (IP67), and fully configurable communication outputs for all possible configurations: IO-Link and PNP/NPN as standard I/O, and 4…20 mA, 0...10 V or NPN/PNP as secondary output.

OPTIBAR PSM 1010 is suitable for liquids and gasses from 0.1...600 bar / 1.5...8700 psi with process temperatures up to +125°C / +257°F and excellent overload resistance.

 OPTIBAR PSM 2010 aims at hygienic applications in the food and beverage industry from 0.1…40 bar / 4…580 psi and max. +150°C / +302°F. Its hygienic construction features a fully welded front-flush diaphragm to meet the most stringent industrial requirements in terms of crevice-free installation with several 3A approved process connections.
