E+E Elektroniks has expanded its product range with various sensors for passive temperature measurement for HVAC and building technology. The compact enclosure with protection class IP65/NEMA 4 facilitates allows for easy and fast installation of the sensors, according to the company. Due to external mounting holes the sensors can be installed with closed housing, which protects the device from building site contamination. The new temperature sensors line matches the design of the E+E humidity, CO2, and air velocity sensors.

The EE431 duct sensor is ideal for the measurement of air temperature in HVAC systems. In air ducts the sensor can be installed with the mounting flange and easily accessible. For measurement in liquids the sensors are mounted with an immersion well with fixing clamp.

The EE441 strap-on sensor can be fixed with a hose clamp onto ducts and pipes. Typical applications include heating systems (hot and cold water pipes) and solar collectors. The aluminum contact surface ensures very good heat transfer and a fast response time.

The EE451 can be used both indoors and outdoors for weather-dependent temperature control of heating, ventilation, and air conditioning systems. A mounting bracket keeps the sensor at a distance from the wall, minimizing the wall temperature influence on the measurement of the air temperature.
The EE461 cable temperature sensor is available with 0.5m to 3m cable length. The star pressing of the sensor sleeve ensures IP65/NEMA 4 protection class. All product-specific information is printed on the cable. For temperature measurement in fluids the EE461 can be used with an immersion well.

The EE471 is available with various cable lengths between the sensing probe and the housing. It can be used for measurement in the air as well as with an immersion well in liquids. Both the probe and the enclosure are IP65/ NEMA 4 rated.
