Humidity sensor measures temperature and air humidity \/ output as standard signal \/ compact \/ Modbus RTU interface \/ wall fastening The humidity sensor PCE-P18-1 can be used to monitor air humidity and temperature in HVAC engineering. The humidity sensor PCE-P18-1 releases the measured indicator as a standard signal 4…20 mA (not galvanic isolated). Air humidity and temperature are detected accurately due to a semiconductor. For operation the humidity sensor PCE-P18-1 is supplied via direct current. The measuring data is then shown via a two-wire line. All connections are made via screwed-contacts with water-proof IP 65 enclosure. The measuring data can be read through a RS485 interface. This feature is especially useful if different measuring points are to be connected during your building monitoring. For further information about the humidity sensor PCE-P18-1 please read the following technical data or use our contact form. Our engineers and technicians will gladly advise you regarding the humidity sensor PCE-P18-1 or any other of PCE Instruments product in the areas of regulation and control or scales and balances.
