EE300Ex-M1

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 com-

plies with the classications for Europe (ATEX), International (IECEx), USA / Canada (FM) and Korea (KCs) for ammable gas and dust

applications.

The entire device can be placed in the explosion endangered area.

The remote sensing probe allows for classication 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 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 puriers 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 Conguration 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 Conguration Adapter and the free EE-PCS Product Conguration Software.

Typical Applications

Chemical process control Pharmaceutical applications Explosive / hazardous storage rooms Flour mills Oil purifiers

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, o󰀨-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.
