KROHNE Pressure switch for basic pressure and level applications
The OPTIBAR PSM 1010 is an electronic pressure switch for absolute or gauge pressure measurement of liquids and gases. The cost-effective pressure switch is suitable for simple process pressure applications (e.g. monitoring of pumps, compressors or other machinery) as well as hydrostatic level measurement in open vessels where space-saving installation is required. Due to its fully welded measuring cell with stainless steel diaphragm, the OPTIBAR PSM 1010 is corrosion-resistant to many aggressive media. Due to its advanced digital compensation, the OPTIBAR PSM 1010 offers excellent temperature stability.
