Series PE 827 — electronic pressure switch with display

• Compact, easy-to-use device • Gauge pressure from -1...0 to 40 bar • 1 analog output 4...20 mA • 2 configurable digital outputs Continuous monitoring in hydraulic and pneumatic applications, in vacuum, refrigeration and gas technologies and in filter monitoring, for switching duties in the -1...0...40 bar range The PE827 is a sturdy, microprocessor-driven device with two switching outputs and a 4-20 mA analog output. This pressure switch uses ceramic technology, proven over many years. Being microprocessor-driven, it gives easy access to the configuration parameters, such as set points and switching functions. Its LED display stays perfectly legible in every circumstance, showing measured values and parameter values, and reporting threshold overruns as well as the chosen measuring unit. This electronic pressure switch has reverse polarity protection and short-circuit protection. The Diagnostic function is reached by a simple keypress. It performs a full check of the electronics and of the measuring cell, and shows the stored pressure peaks.
