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.
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.
