Humidity and Temperature Sensor for Industrial Applications EE23
v5.4 / Modification rights reserved | 2 EE23 The EE23 is optimized for reliable and cost effective use in industrial applications. In addition to highly accurate measurement of relative humidity (RH) and temperature (T), the sensor also calculates the dew point (Td) and the frost point temperature (Tf). Measurement Performance The EE23 employs high-end E+E humidity sensing elements manufactured in state-of-the-art thin-film technology, which are the prerequisite for outstanding accuracy. Long Term Stability The E+E proprietary coating protects the sensing elements against corrosive and electrically conductive pollution, which leads to outstanding long-term stability even in harsh environment. With the appropriate choice of filter cap, the EE23 tackles even challenging industrial applications. Outputs and Power Supply The measured data is available on two voltage or current outputs as well as on the display. Additional features like alarm (relay) output and integrated supply module 100 - 240 V AC facilitate the use of the EE23 in a wide range of applications. Easy Installation and Service The modular, three parts design of the IP65 / NEMA 4 enclosure, available in polycarbonate or metal, facilitates easy installation, service and replacement. The enclosure consists of the back cover with the terminals for wiring, the pluggable active part with the electronics and the probe, and the front cover. Once installed, the active part of EE23 can be plugged on and off without rewiring. The plastic enclosure is appropriate also for mounting onto DIN rails. Remote Probe and Accessories The remote probe with cable length up to 10 m (32.8 ft) together with a wide choice of accessories such as mounting flanges or brackets, drip water protection or radiation shield allow for easy integration of the EE23 into any measurement task. User Configurable The user can easily perform a two-point humidity and temperature adjustment. The analogue and alarm outputs can be freely configured.

v5.4 / Modification rights reserved | 4 The E+E proprietary sensor coating is a protective layer applied to the sensing elements, their leads and soldering points. The coating substantially extends sensor lifetime and ensures optimal measurement performance in corrosive environment (salts, off-shore applications). Additionally, it improves the sensors’ long term stability in dusty, dirty or oily applications by preventing stray impedance caused by deposits on the active sensor surface or on the electrical connections.
