EE300Ex-HT
The EE300Ex humidity / temperature transmitter has been
designed specifically for measurement in explosion hazard
areas. It complies with the classifications for Europe (ATEX),
International (IECEx) and USA / Canada (FM).
Accurate measurement over the full range of 0…100 % RH
and -40…180 °C (-40...356 °F) is also possible in applications
under pressure from 0.01 … 300 bar (4351 psi).
The EE300Ex can be used in flammable gas and dust
applications. The entire transmitter can be placed in a
explosion hazardous area. With the remote sensing probe a
temperature classification up to T6 can be reached.
With a stainless steel enclosure and sensing probe the
EE300Ex is the ideal transmitter for challenging industrial
applications. The 2-part construction facilitates simple installa-
tion and rapid replacement of the measuring section without
time consuming wiring. The well proven E+E humidity sensors
ensure reliable measurement performance and long term
stability.
Based on 2-wire technology, the transmitter can be
powered by any intrinsically safe power source or via Zener
barriers. The measured values are available on two 4…20mA
analog outputs. In addition to the measured values for humidity and temperature, the EE300Ex calculates
dew point, frost point, absolute humidity, mixing ratio and other humidity related physical quantities.
When outside of the hazardous measurement area, the setup of the EE300Ex can be easily customized by
using the supplied configuration software. This includes the configuration of the analog outputs and the cali-
bration of the humidity and temperature during service.
Measurement of moisture in oil:
Besides measurement in the air, the EE300Ex can be employed for measurement of both absolute water
content (x) in ppm or relative water activity (aw) in oils.
Typical applications include oil purifiers and online monitoring of lubrication and hydraulic oils on off shore
oil rigs.
The USA and Canada approval is valid for air and gas measurement only.
