Krohne OPTIBAR PSM 1010 and PSM 2010 pressure switches

Krohne has introduced the OPTIBAR PSM 1010 and OPTIBAR PSM 2010 ultra-compact pressure switches for absolute and gauge pressure measurement in gases and liquids.

Both devices are aimed 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 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 high temperature stability due to 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.

OPTIBAR PSM 2010 is aimed at hygienic applications in the food and beverage industry from 0.1–40 bar (4–580 psi) and a maximum temperature of +150°C. Its hygienic construction features a fully welded front-flush diaphragm to meet requirements in terms of crevice-free installation with several 3A-approved process connections.
