EE046 EE046 condensation monitor helps prevent condensation on chilled beams and other critical cold spots and is appropriate for mounting onto plane surfaces and on pipes with max. 50 mm (2”) diameter. It features the well-proven E+E HC105 SMD humidity sensor. Condensation on a surface occurs when the relative humidity (RH) of the air close to the surface reaches 100 % RH. Because of very good thermal coupling with the surface, EE046 measures directly the RH of the air at surface temperature. The relay output gives an early warning when approaching condensing conditions, before condensation actually happens. It indicates also a power supply failure or a broken cable. A status LED indicates normal operation, alarm or power supply failure. The E+E proprietary coating protects the humidity sensor against dust and dirt. Features fast response time dust protection compact design and easy mounting LED status indication Typical Applications early detection of condensation danger chilled beams switching cabinets climate control Technical Data Humidity sensor Working range Threshold at 20 °C (68°f), 24 V AC/DC Hysteresis Response time at change of the surface temperature Response time at change of the relative humidity Electrical output Switching capability Supply voltage (Class IN) Current consumption Relay status indication Electrical connection Protection sensor / electronics Housing protection class Housing material Electromagnetic compatibility Temperature range operation storage Weight potential free relay with changeover contact max. 24 V AC/DC, 1A 24 V AC/DC ±20 % < 6 mA for 24 V DC supply < 10 mA for 24 V AC supply LED, red 5-pole push-in terminal, max. 1.5 mm2 (awg 16) E+E proprietary coating / varnish IP40 Polycarbonate, UL94-V2 approved EN 61326-1 EN 61326-2-3 industrial environment 0...50 °C (32...122 °F) -20...70 °C ( -4...158 °F) approx. 60 g
