EE300Ex - Reliable Measurement in Gas and Dust Hazardous Areas

The EE300Ex can be directly mounted in the highest hazard zones. The highly accurate RH and T sensor is thus ideal for demanding applications, e.g. in the petrochemical or pharmaceutical industry. Further application areas are explosive storage rooms, grain mills, power stations, paint booths and offshore platforms.

  • EE300Ex humidity and temperature sensor
    Due to the high-quality stainless steel enclosure, the EE300Ex is suitable for a wide range of applications.

EE300Ex Humidity and Temperature Sensor

For Explosion Hazard Areas Zone 0/20

The EE300Ex allows for precise RH and T measurement in the range -40…180 °C (-40...356 °F) and up to 20 bar (290psi) pressure.

The sensor can be mounted directly in the gas and dust hazard area zone 0/20.

The measured data is available on two analogue outputs (4…20 mA, 2-wire) and on the optional display.

Besides measurement of RH and T, the EE300Ex calculates all humidity related parameters, such as dew-point temperature [Td], absolute humidity [dv] or mixing ratio.

Easy Installation and Service

The Two-Part Enclosure

The stainless steel enclosure consists of a separated connection and measurement unit. This simplifies considerably the installation of the transmitter and allows for easy replacement of the measurement unit – for calibration or service purposes– without time-consuming re-wiring.

EE300EX employs the 2-wire technology and must be loop-powered by an intrinsically safe supply unit.

The two 4...20 mA outputs can be easily configured by the user.

Maximum Flexibility

Various models and options enable the EE300Ex to meet specific application requirements.
