YOUR PARTNER IN SENSOR TECHNOLOGY ELEKTRONIK* Ges.m.b.H. Condensation Monitor EE46 condensation monitors are used to monitor the formation of condensation on chilled ceilings or to prevent condensation at critical spots of heating-, ventilation- and air conditioning systems. It is also used as a dew point monitor for systems operating near the dewpoint. Because of the temperature coupling between the condensation monitor and the environment, the relative humidity is a measure for the dew point. The condensation monitor measures the relative humidity near the dew point using its high-quality capacitive sensor. At reaching the switching point of 90% RH the output will provide an early warning signal for the initiation of control steps (increasing the initial water temperature, reducing the cooling capacity, switching on the heating, etc...). An additional status light indicates the condensation danger. Thanks to the special protection coating, sensor and electronics are highly insensitive to dust EE46 condensation monitors can be mounted on walls, ducts and pipes up to 2". Typical Applications- chilled ceilings heating-, ventilation- and air conditioning systems switching cabinets Technical Data Humidity sensor Working range Switching point at 20°C (68°F) Switching hysteresis -Features early detection of condensation danger compact design fast response time dust protection simple and easy mounting status indication Response time at change of pipe/wall temperature Response time at change of relative humidity Electrical output Switching capacity Supply voltage Current consumption at 24V DC Relay status indication Electrical connection Dust protection Housing protection class Housing material Electromagnetic compatibility Temperature range potentialfree relay with changeover contact max. 24V AC/DC, 1A 24V AC/DC ±20% < 3mA LED, red 5-pole push-in terminal, max. 1.5 mm2 (AWG 16) by special coating (permeable for water vapour) IP40 Polycarbonate, UL94-V2 approved EN 61326-1 EN 61326-2-3 industrial environment working temperature range 0...50°C (32...122°F) storage temperature range -20...70°C (-4...158°F)
