Heated Humidity and Temperature Probe for Meteorological Applications EE260
v1.6 / Modification rights reserved | 2 EE260 The EE260 probe is optimized for accurate and reliable relative humidity (RH) and temperature (T) measurement in meteorology and demanding outdoor applications. Innovative, Compact Design The design of the EE260 integrates a heated humidity sensing head and an additional T sensing element into one single compact probe. The device is thus compatible with rotation symmetric radiation shields. Measurement Performance The dual heating system prevents condensation on the RH sensing element, on the probe head and on the filter cap, which leads to very short response time and fast recovery after condensation. Furthermore, it enables precise RH measurement even under continuously high humidity and condensing conditions. Versatility Besides the measurement of RH and T, the EE260 calculates other humidity related quantities like dew point temperature (Td), absolute humidity (dv) and mixing ratio (r). Reliability, IP67 Protection Rating The proprietary E+E coating protects the RH sensing element and its leads against corrosive and electrically conductive pollution. The encapsulated electronics are optimally protected against environmental influences. Analogue Outputs and Digital Interface The EE260 features two freely configurable and scalable voltage outputs as well as an RS485 interface with Modbus RTU protocol. The measured data is available at the analogue and digital interfaces simultaneously. User Configurable and Adjustable An optional configuration adapter and the free PCS10 Product Configuration Software facilitate the configuration and adjustment of the EE260.

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.
