Electronic Pressure Switch
Electronic Pressure Switch
The SC400 is available as a pressure switch [2 switching outputs] and as a pressure sensor [4…20 mA or 0…10 V] with an additional switching output. The integrated LED display provides a continuous pressure indication and allows together with the programming buttons an easy set-up of the pressure switch. There are nearly no limits for mounting the pressure switch SC400, because of the turnable display and the optional turnable process connection. Applications: vacuum, filter monitoring, level monitoring, hydraulic/pneumatics, refrigeration, engine building industry, building services. Technical data: ranges – -1 to 700 bar; output – 2 free programmable switching points [SP] or 1 SP + 1 scaleable analogue output 4-20 mA or 0-10 V; repeatability – 0.2% FS; media – liquids or gases; wetted parts – stainless steel or ceramic NBR gasket; pressure connection – G ¼; media temperature – -20…80ºC; electrical connection – round connector M 12 x 1; 4-pin; and protection class – IP65. Special features: integrated password protection, display-head and optional pressure connection 330º turnable; analogue output scaleable (minimum 20% of span); switching points, hysteresis and switching function [NC/NO] over display programmable; PNP-or NPN-switching output programmable; attenuation 0 to 2 seconds programmable; easy 2-key programming; min-/max-pressure memory; integrated polarity; and overvoltage protection.
