Humidity and Temperature Sensor for Intrinsically Safe Applications The EE300Ex intrinsically safe sensor reliably measures relative humidity (RH) and temperature (T) in explosion hazard areas. It complies with the classifications for Europe (ATEX), International (IECEx), China (NEPSI), USA / Canada (FM) and Korea (KCs) for flammable gas and dust applications. The EE300Ex it is also certified for gas applications according Japan (TIIS) certifications. The entire device can be placed in the explosion endangered area. The remote sensing probe allows for classification up to T6. Measurement performance The well proven E+E humidity sensors and competence in calibration allow for highly accurate and long term stable measurement over the full range 0…100 % RH and -40…180 °C (-40...356 °F), with pressure rating up to 20 bar (300 psi). Besides the RH and T measurement, the EE300Ex calculates all humidity related parameters such as dew point temperature (Td), frost point temperature (Tf), absolute humidity (dv) or mixing ratio (r). Moisture in oil measurement The EE300Ex with ATEX, IECEx, NEPSI and KCs approval is suitable also for measuring water content (X) in ppm and water activity (aw) in isolation, lubrication and hydraulic oils. Typical applications include oil purifiers and online monitoring of lubrication and hydraulic oils. Supply and outputs The device can be powered by any intrinsically safe supply unit or via Zener barriers. The measured or calculated data is available on two 4…20 mA, 2-wire outputs and on the LCD display. Robust, functional design The stainless steel enclosure and sensing probe are suitable for harsh environment in challenging industrial applications. The EE300Ex design facilitates the installation as well as the replacement of the measuring section (electronics and probe) without time consuming wiring. Easy Configuration and Adjustment The setup of the analogue outputs as well as the adjustment of the RH and T reading can be easily performed with the optional EE-PCA Product Configuration Adapter and the free EE-PCS Product Configuration Software. Typical Applications Chemical process control Pharmaceutical applications Explosive / hazardous storage rooms Flour mills Oil purifiers Features Gas and dust in zone 0 / 20 and Div. 1 Stainless steel enclosure and probe Best accuracy up to 180 °C (356 °F) Pressure tight up to 20 bar (300 psi) Inspection certificate according to DIN EN 10204-3.1 v2.12 / Modification rights reserved

Protective sensor coating The E+E proprietary sensor coating is a hygroscopic layer applied to the sensing elements, their leads and soldering points. The coating substantially extends sensor life-time and ensures optimal measurement performance in corrosive environments (salts, off-shore applications). Additionally, it improves the long term stability of E+E sensors in dusty, dirty or oily applications by preventing stray impedance caused by deposits on the active sensor surface or on the electrical connections. v2.12 / Modification rights reserved
