The E+E EE300Ex Humidity and 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). The EE300Ex features an accurate measurement over the full range of 0 to 100 % RH and -40 to 356°F (-40 to 180°C).

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 installation 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

Applications for the EE300Ex include:

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