EE 21 humidity transducer |
|
|
The EE 21 humidity transducer has been designed to perform very accurate humidity and temperature measurements. The EE 21 humidity transducer is provided with special sensors to ensure the highest accuracy. The EE 21 humidity transducer is available in different versions. The EE 21 humidity transducer can be wall-mounted or mounted in a channel. The EE 21 humidity transducer is usually delivered with an analogue output. A current or a voltage output can be selected. The EE 21 humidity transducer is typically used in greenhouses, warehouses, pools, meteorology and applications in which a high accuracy as well as an operational security are required. Thanks to its wide measurement range, which goes from -40 °C to +60 °C, the EE 21 humidity transducer can be used in many different sectors. The EE 21 humidity transducer has IP 65 protection which makes it very resistant to external influences such as water. The EE 21 humidity transducer is the ideal instrument to be used in adverse conditions in the industrial sector. A special layer ensures the sensor long life and also provides the humidity transducer with the security that is required in very dirty environments. Different filters are available to ensure a proper sensor protection. At the following link you will find other humidity transducer models. |
