Duct humidity and temperature sensor (± 2.0%) HYGRASGARD® KFTF - EtherCAT P

Display

Product group: WG02

Interconnective HYGRASGARD® KFTF - EtherCAT P duct humidity and temperature transmitter with M8 plug-in connector (EtherCATP-encoded), Bluetooth-enabled, in an impact resistant plastic housing with quick-locking screws, optionally with/without display and bar graph, with plastic sinter filter (replaceable), incl. mounting flange.

The sensor device serves to detect various parametres in humidity measurement. It measures relative humidity (0...100% RH) and ambient air temperature (–35...+80°C). These measurands are used internally to calculate further output values: absolute humidity (0...80 g/m³), mixture ratio (0...80 g/kg), dew point temperature (–20...+80°C) and enthalpy (0...85 kJ/kg) while ignoring atmospheric air pressure. A long-term stable, digital sensor guarantees precise measuring results. The sensor is factory-calibrated.

EtherCATP-enabled measuring transducer for industrial requirements with maximum reliability: includes easy PLC integration using the devices ESI configuration file, diagnostics (such as communication failure counter), advanced setting options, access to historical data (min/max) and sensor service interval determination. Optionally with large back-lit three-line display (witjh customised programming in the 7-segment and dot-matrix ranges) and bar graph (7-digit, LEDs freely configurable) for graphical display, e.g. as a traffic light indicator.
