New ultra-compact pressure switches with IO-Link

  • For basic automation in food and beverage, water and wastewater, environmental and OEM equipment applications
  • Configurable PNP/NPN switching output with IO-Link connectivity
  • 2-axis (multi-rotatable) LED display and adjustment module

KROHNE introduces OPTIBAR PSM 1010 and OPTIBAR PSM 2010 ultra-compact pressure switches for absolute and gauge pressure measurement in gases and liquids.

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. Target industries include food and beverage, water and wastewater, environmental and OEM process equipment applications with restricted installation space.

The new 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. Both devices offer excellent temperature stability due to advanced digital compensation.

OPTIBAR PSM 1010 is suitable for liquids and gases 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.
