3 Product Description

3.1 General

The EE260 probe is optimized for accurate and reliable relative humidity (RH) and temperature (T) measurement in meteorology and demanding outdoor applications.

Mounted in its upright position, the air first passes over EE260‘s Pt100 temperature sensing element, then over the heated probe shaft and over the heated humidity sensing element. This dual heating system prevents condensation or icing of the RH sensing element, on the probe head and on the filter cap. This leads to short response times and fast recovery as well as to precise RH measurement even under continuously high humidity and condensing conditions.

User Manual EE260 Heated Humidity and Temperature Probe for Meteorological Applications

Page 6

The proprietary E+E sensor coating, the encapsulated electronics and the UV resistant and T stable elastomere enclosure make the probe reliable, long-term stable and very well protected against environmental influences.

The EE260 measures RH and T and calculates the following humidity related parameters:

Dew point temperature (Td)



Frost point temperature (Tf)



Wet bulb temperature (Tw)



Water vapour partial pressure (e)



Mixing ratio (r)



Absolute humidity (dv)



Specific enthalpy (h)



The RH and T measured values are available on two freely congurable and scalable voltage outputs as

well as on the RS485 interface with Modbus RTU protocol. The values of the calculated parameters are available on RS485/Modbus RTU.

6 Maintenance and Service

EE260 does not require any special maintenance, nevertheless for high accurate measurements especially over wide RH and T ranges it is recommended to calibrate the probe every 12 months. If needed, the enclosure may be cleaned and the device may be re-adjusted as described below.

6.1 Cleaning

Use a damp soft cloth to remove deposits of dust or dirt from the exterior of the probe. Do not use any solvents or abrasive cleaning agents and no isopropanol (isopropyl alcohol).

In case of dusty, oily and polluted environment:

Use a damp soft cloth to remove deposits of dust or dirt from the exterior of the probe. Do not use



any solvents or abrasive cleaning agents. The filter cap shall be replaced once in a while with an E+E original one (see below).



If needed, the sensing element of the humidity probe can be cleaned by the user (see the E+E



cleaning instructions)

6.2 Filter Replacement

In a dusty or polluted environment it might be necessary to replace the filter cap or the filter membrane, respectively, once in a while. In most of the cases, a clogged filter shows visible contamination or dirt. Longer response time of the humidity measurement also indicates a clogged filter cap. In such cases, replace the filter cap or the filter membrane by a new, original one, see chapter „6.6 Spare Parts“.

Procedure

Turn the filter cap counter-clockwise for removing it.



Install the new filter cap finger tight by turning it clockwise.



While replacing the filter cap take very good care to not touch or rub the sensing element.

6.3 Repairs

Repairs may be carried out by the manufacturer only. The attempt of unauthorized repair excludes any warranty claims.

6.4 RH / T Adjustment and Calibration

In meteorological applications there might arise the need for periodical humidity and temperature calibration or adjustment.

Definitions

Calibration documents the accuracy of a measurement device. The device under test (specimen) is



compared with the reference and the deviations are documented in a calibration certificate. During the calibration, the specimen is not changed or improved in any way.

Adjustment improves the measurement accuracy of a device. The specimen is compared with the



reference and brought in line with it. An adjustment can be followed by a calibration which documents the accuracy of the adjusted specimen.

User Manual EE260 Heated Humidity and Temperature Probe for Meteorological Applications

Page 14

6.4.1 Calibration and Adjustment at E+E Elektronik

Calibration and/or adjustment can be performed in the E+E Elektronik calibration laboratory. For information on the E+E capabilities in ISO or accredited calibration please see www.eplusecal.com.

6.4.2 Humidity Calibration and Adjustment by the User

Depending on the level of accuracy required, the humidity reference can be:

Handheld device (e.g. Omniport 30), please see www.epluse.com/omniport30.



Humidity standards (e.g. Humidity Calibration Kit), please see www.epluse.com/EE260.



Please note: It is of very high importance that for the RH calibration the RH and T sensing elements

are at the same temperature. Please contact your sales representative for assistance.

Please note: When the calibration/adjustment procedure with the help of EE PCS starts, both heating modes of the EE260 are disabled automatically if they have on status. At the end of the procedure the heating comes back to on automatically.

Fig. 6 Setting the Heating Mode in E+E Configurator

Please observe these important notes on changing the sensing element data:

■ The sensing element data generally only has informational character.

■ For all applications, an alleged drift of the device can be corrected using the offset correction or the

one/two point adjustment offered by the EE-PCS.

■ For very special requirements, the drift can be corrected acting upon the characteristic of the sensing

elements, i.e. upon the sensor data such as nominal capacity or humidity coefficient. This requires deep knowledge about the sensing elements and the design of the measuring device.

User Manual EE260 Heated Humidity and Temperature Probe for Meteorological Applications

Page 15

■ Important! Contact the E+E sales representative before any attempt of acting upon the sensing

element data!

■ Caution! Upon changing the sensing element data, the original data is lost. There is no way to

automatically return to the original sensor data. Please make sure to note and save the original sensing element data before making any change!

6.4.3 Temperature Calibration and Adjustment by the User

For a reproducible T calibration or adjustment, it is recommended to measure the Pt100 of the EE260 in a liquid bath. This reduces the T inhomogeneity surrounding the probe to a minimum. It must be ensured to use an inert, nonconductive liquid which does not chemically contaminate the sensor element (e.g. GALDEN HT200).

The temperature reference (T-Ref) shall be located at the same level as the Pt100 of the EE260.
