Duct mounting HVAC transmitters.

The new EE150 humidity & temperature transmitter has been optimised specifically for use in the HVAC and building technology sectors and impresses with an outstanding price/performance ratio.

The clever housing concept, the compact design and the 6mm diameter probe simplify mounting of the transmitter, which results in minimized installation costs. The IP65/NEMA 4 enclosure provides optimal protection of the electronics and the capacitive E+E humidity sensor element guarantees long-term stable measurement results.

The transmitter features a particularly installation-friendly design. Thanks to the external mounting holes it is not necessary to open the housing for mounting. This means that the electronics are protected against construction site pollution. For duct mounting the RH/T probe of just 6mm in diameter does not require a hole any larger than a standard T probe. The mounting flange further simplifies installation of the transmitter. The benefits are shorter mounting times and thus minimized installation costs.

The PTFE filter cap protects the sensing head against contamination, ensuring excellent long-term stability. The measured values are issued via two 0-10V or 4-20mA analog outputs. Using an optional configuration kit and the free software, the user can set the output scaling and perform a 1 or 2 point adjustment for humidity and temperature.
