Humidity/Temperature Transmitter for Intrinsically Safe Applications 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 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. EE300Ex - remote sensing probe 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 calibration 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. Dew point measurement in natural gas. EE300Ex measures reliably dew point in natural gas down to -20 °C (-4 °F) at a line pressure up to 250 bar (3625 psi). The optional sensor retraction tool (see accessories) allows for easily installation and removal of the sensing probe for service or calibration without interruption of the gas flow in the pipeline.

Display Two of the measured or calculated physical quantities can be selected with push buttons on the front cover to be shown on the optional display. EE300Ex version with display is not available for environments with combustible dust, Fibers and Flyings and gases with EPL Ga IIC (Group A&B). The gray area shows the allowed measurement range for the humidity sensor. Operating points outside of this range do not lead to destruction of the sensing element, but the specified measurement accuracy cannot be guaranteed.
