Both gadgets are designed for basic automation applications corresponding to hydrostatic degree measurement in open tanks, dry-run protection of supply pumps or pressure monitoring of compressors, hydraulic and pneumatic techniques. pressure gauge 10 bar and beverage, water and wastewater, environmental and OEM process gear applications with restricted set up space.
The new switches function a 2-axis (multi-rotatable) display and adjustment module, a sturdy building (IP67), and absolutely 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 supply high levels of temperature stability due to superior digital compensation.
Krohne’s OPTIBAR PSM 1010 is suitable for liquids and gases from 0.1…600 bar/1.5…8700 psi with course of temperatures as much as +125°C/+257°F and excellent overload resistance.
OPTIBAR PSM 2010 goals at hygienic applications in the meals and beverage trade from 0.1…40 bar/4…580 psi and max. +150°C/+302°F. Its hygienic construction features a totally welded front-flush diaphragm to fulfill the most stringent industrial necessities when it comes to crevice-free set up with a quantity of 3A permitted course of connections.
