| 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) and USA / Canada (FM) 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). | |
| Type | EE300Ex Intrinsically Safe Humidity / Temperature Transmitter with remote sensor probe |
| EE300Ex Intrinsically Safe Humidity / Temperature Transmitter for wall mounting | |
| Detail | 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. |
