The EE99-1 OEM - Relative Humidity / Temperature modules are designed to meet the specific requirements of RH/T monitoring in climate chambers. High-end E+E humidity sensor elements of the HC series and accurate temperature compensation of the humidity reading result in an excellent accuracy over a broad measurement range. The analogue output for relative humidity is 4 - 20mA (3-wire). The passive temperature output can also be connected via 3-wire to an external readout. Easy mounting and service is possible with a plug-in screw terminals block and by push buttons for field calibration. Sensor Coating: Operation in heavily polluted and/or corrosive environments is typical for many industrial processes and can lead to drift or damage of the humidity sensor and therefore to incorrect measurements. The unique protective coating developed by E+E for the sensing probe (ordering code: -HC) means a significant improvement of the long-term stability of the transmitter in very dirty and aggressive environments.
