Galltec Light Humidity-temperature sensors
Product Descriptions
• for measuring relative humdity (h.r.) and temperature
• with capacitive Mela® sensing element
• for use in air-conditioning systems
• building management systems
• ventilation technology
• different models
These sensors have been specially adapted to the needs of the ventilation and air-conditioning sector. They come in three series (the WL series for wall mounting, the KL series for duct installation and the PL series with a cable for suspension from any location). The KL and PL series are equipped with gauze filters as standard. Other filters are available on request. Use of capacitive humidity sensor elements is a guarantee of high long-term stability, resistance to dew formation, small hysteresis and good dynamic performance
