EE300Ex
Humidity and temperature transmitter for intrinsically safe applications
The EE300Ex humidity and temperature transmitter is dedicated for measurement in explosion hazard areas. It complies with the classifications for Europe (ATEX), International (IECEx), USA / Canada (FM), China (NEPSI) and Korea (KCs) and can be employed in gas and dust explosion hazard areas. The intrinsically safe EE300Ex can be installed in the explosion hazard area even in zones 0 / 20 (Divison 1).

The 2-part enclosure facilitates easy installation and dismounting for calibration without time-consuming wiring. The robust and easy-to-clean stainless steel housing is optimized for the pharmaceutical and chemical industries. The well proven E+E humidity sensor technology grants reliable, long-term stable measurements in challenging applications.
Besides measurement of relative humidity and temperature, the EE300Ex calculates all humidity related parameters, such as dew-point temperature [Td], wet-bulb temperature [Tw], absolute humidity [dv], etc. The intrinsically safe humidity and temperature transmitter features two 4-20 mA outputs in 2-wire technology.
Moisture in oil measurement
In the same way as humidity measurement in air, the EE300Ex is appropriate for moisture in oil measurement. The moisture content of oil can be issued absolute as water content in [ppm] or relative as water activity [aw]. Typical applications for moisture in oil measurement are found in systems for cleaning/drying oil or on oil platforms for online monitoring of lubrication and gear oils.

EE300Ex FAQ
May I change or remove the label of my ATEX device?
No, this is not allowed. The ATEX devices must carry the original manufacturer labels at all times.
What calibration certificate is included in the standard scope of supply of the ATEX E+E humidity and temperature measurement devices?
The standard scope of supply of ATEX E+E humidity and temperature measurement devices includes an inspection certificate according DIN EN 10204 - 3.1. For details on calibration certificates please see page 5 in www.kalibrierdienst.at/fileadmin/content/White_Paper_Calibration_and_traceability_in_measuring_technology.pdf
Can E+E supply an accredited calibration certificate with the ATEX transmitter?
Accredited calibration certificate for ATEX E+E humidity and temperature measurement devices is available upon request, please see our calibration website.
What is the difference between a 2 wire and a 3 wire current output?
Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
