General Safety Instructions

Excessive mechanical loads and incorrect usage should always be avoided.

•

• Take care when unscrewing the filter cap as the sensor element could be damaged.

• The sensor is an Electro Static Discharge sensitive component (ESD). When touching

the sensor element, ESD protective measures should be followed.

• Grip sensors only at the lead wires.

• Installation, electrical connection, maintenance and commissioning should be performed

by qualified personnel only.

• The devices are constructed for the operation of separated extra-low voltage (SELV).

Safety instructions for use of the alarm module with voltages >50V

To insulate the optional alarm module from the low-voltage side of the transmitter, the

•

partition provided for this purpose must be fitted in the lower section.

• During operation of the instrument the modular housing must be completely closed.

• The protection class of an opened housing corresponds to IP00 and direct contact

with components carrying dangerous voltages is therefore possible. In general, work on live components should be avoided and when absolutely necessary, should be performed by qualified personnel only.

Safety instructions for use of the integrated power supply (option V01)

During operation of the instrument the modular housing must be completely closed.

•

• The protection class of an opened housing corresponds to IP00. In general, work on live

components should be avoided and when absolutely necessary, should be performed by qualified personnel only.

• The bottom part and the middle part of the housing must be grounded during operation.

The electronics must be collected as electronic scrap and disposed of according to the regulations in force.

Hardware

2. PRODUCT DESCRIPTION

The EE33 series provides all the functions of a multifunctional humidity/temperature transmitter with one major difference - it is equipped with a heated measurement cell.

The heated measurement cell contains a combined (monolithic) humidity/temperature sensor element and enables reliable long-term measurements in extremely humid or chemically polluted environments. With a special high-pressure probe the transmitter can be used at process pressures up to 100bar (1450psi).

The operating modes of the heated measurement cell depend on the conditions. The parameters of the different operating modes are as follows:

Heat intensity:

Automatic recover: The measurement cell can be heated intensively to evaporate chemical residue or temporary condensation. Warming: The measurement cell can be warmed slightly to prevent condensation in environments with continuous high humidity.

Heating time:

The measurement cell can either be heated briefly (the heating time can be defined in the configuration software) before returning to the ambient temperature or it can be warmed continuously.

Start of heating:

Manual: Heating is started by a control element on the PCB.

Automatic: Heating is triggered when a defined humidity set point is exceeded (configuration software).

Recurrent: Heating is recurrent and triggered after a defined cycle time (configuration software).

Distinctive models, sensing probes and mounting versions allow for the EE33 series to be utilized in numerous applications.

2.1 Operating modes and conditions

2.1.1 Automatic ReCover (ARC)

Chemical pollution: When capacitive humidity sensors are exposed to chemical pollution (e.g. detergent residue), the presence of foreign molecules can distort the measurement reading.

The foreign molecules can be evaporated by heating the measurement cell briefly and intensively. Reconditioning helps to minimize distorted measurement readings during the calibration interval.

Temporary condensation: Temporary dew (e.g. in misty environments) is identified by defining a humidity set point value (e.g. 99%) and can be evaporated by heating the measurement cell intensively for 10 seconds.

Thanks to its monolithic structure, the measurement cell cools off quickly (approx. 3 minutes) to reach once again the same humidity content as the environment.

If condensation is still detected at the end of the heating and cool-down times, the process starts again after a defined cycle time (30 minutes).

Hardware

2.1.2 Overheating / Warming (OH = Overheating)

Continuous high humidity: Even the smallest deviation between the temperature of the sensor head and the ambient temperature can cause dew on the sensor element in conditions of continuous high humidity (e.g. in mushroom drying). Dew on the humidity sensor element prevents accurate measurement of the actual humidity.

However, the EE33 series minimizes the relative humidity on the measurement cell through regularly warming. The relative humidity and temperature of the warmed measurement cell can be determined precisely thanks to its monolithic structure. The dew point of the environment is calculated from the measuring values.

If the relative humidity has to be determined near condensation, the ambient temperature can be measured with an additional temperature sensor to calculate the relative humidity.

2.1.3 High process pressure up to 100 bar (1450psi) / high-pressure probe (HPP = High Pressure Probe)

Thanks to the combination of the heated measurement cell with a new high-pressure probe, the transmitter can be used in applications with high process pressure and wide working range in humidity and temperature.

The special high-pressure probe's innovative pressure tight feed through sets it apart from the remote probes in other models.

Special ball valves enable assembly without interrupting the process and are available on request.

General safety instructions for installation

Because the sensing probe can be exposed to very high pressures in the measurement environment, there is the risk of sudden, unintentional expulsion of the probe during or after improper installation. Therefore, special precautions should be taken when working on the sensing probe or in its vicinity. Bending over the sensing probe should be avoided underany circumstances!

During the installation of the sensor probe, make sure that the surface of the sensing probe is not damaged! Damaging the probe could lead to damaged seals (consequence: leakage and pressure loss) and to problems during removal (jamming).

Installation of the probe directly in the process

For direct probe installation, a stop valve should be provided on both sides of the probe insert. This allows the sensor probe to be removed for maintenance and calibration without any problems.

7. HUMIDITY / TEMPERATURE CALIBRATION

The EE33 transmitter series can be calibrated in two ways:

- 1-point humidity/temperature calibration: quick and simple calibration on a defined humidity/temperature

point (working point).

- 2-point humidity/temperature calibration: calibration for accurate measuring results over the whole

humidity/temperature working range.

• To reach a temperature balance it is recommended to keep the transmitter and the

reference chamber (e.g. HUMOR 20,...) for minimum 4 hours in the same room.

• During stabilisation period and calibration procedure it is important to keep the temperature constant

in the reference climate chamber.

• For calibration the humidity sensor probe must be stabilised at least 20 minutes into the reference chamber.

• Replace an used dirty filter cap before calibration!

7.1 2-point humidity calibration

For accurate adjustment over the whole humidity working range a 2-point calibration is recommended.

• Start calibration at the low humidity calibration point!

• The humidity difference between the two points should be > 30%RH

• Low humidity point < high humidity point

• 2-point calibration may be performed directly on the circuit board, or using the configuration software

supplied (for more details, see Configuration Software, chapter 5.4 ”2-point humidity calibration”)

7.3 1-point humidity calibration

When the working range is limited to a certain more narrow range, a calibration at one humidity point is absolutely sufficient.

• In accordance with the working range, either the high or low

calibration point should be selected. (CP > or < 50% RH)

• This calibration causes an extra inaccuracy for the rest of the

working range.

• The 1-point humidity calibration may be done directly on the

circuit board, or for convenience, using the configuration software supplied. (for more details, see Configuration software,

7.6 Adjustment/Calibration EE33 model J

7.6.1 Adjustment/Calibration with humidity calibrator HUMOR 20

To be able to calibrate the transmitter of the series EE33-MFTJ, with the dual probes (Td-probe and T–probe), a separate available adapter is needed (siehe Hardware, chapter 10. replacement parts/accessories - adapter for EE33 - model J, HA020401) to achieve the highest possible calibration result. The following steps describe how the series EE33-MFTJ should be calibrated correctly.

1. Plug both air vents of the cover of the measurement chamber with the plugs supplied with the adapter (see left picture).

2. Insert the Td-probe (Ø12mm) in the measuring chamber through one of the feed-throughs of the cover and tighten the nut.

3. Insert and tighten the T-probe (Ø6mm) in the adapter and insert in the measuring chamber through one of the feed-throughs of the cover and tighten the nut.

4. In case that feed-throughs are not in use, close them with the blind plugs delivered with the cover.

Transmitters delivered after June 2009 have the possibility to heat the tube of the probe continuously to avoid condensation. This function must be

disabled prior to calibration, by detaching the cover of the transmitter and removing the “heat”-jumper in the left top corner of the PCB (see left picture).

5. Connect the test unit to the supply connections of HUMOR 20.

6. Connect the output signal of the test unit(s) to the internal measuring inputs of HUMOR 20 (Unit1 RH, Unit2 RH).

7. Select the measuring ranges in accordance with the output signal of the test units. The temperature of the measuring chamber can be displayed by selecting "Temp." on the measuring range switch.

8. Use the humidity controller to select the setpoint of the humidity.

9. For information on the standard deviations and stabilisation times of the test unit, refer to the manufacturer's documentation (however, a minimum of 20 mins is recommended).

10. Compare the values shown in the display with the output signal of the transmitter.

Hardware

After calibration, make sure that the plugs in the air vents in the cover of the measuring chamber are removed.

7.6.2 Adjustment/Calibration with various calibrators

For an exact calibration, note especially point 4 in the above chapter.

8. MAINTENANCE

8.1 Sensor cleaning

It is easy to clean the sensor if there are particle deposits (e.g. dust) on the surface of the heated measurement cell.

Commercially available isopropyl alcohol is used for cleaning. Unscrew the filter cap and submerge the sensor element in the alcohol for 2 minutes. Allow the sensor element to dry or blow it dry with oil-free compressed air.

Caution: In order to avoid destroying the active sensor coating, avoid using mechanical aids (e.g. cotton swabs or cloths) for cleaning!

8.2 Automatic ReCover (ARC)

When capacitive humidity sensors are exposed to chemical pollution (e.g. detergent residue), the presence of foreign molecules can distort the measurement reading. The foreign molecules can be evaporated by heating the measurement cell briefly and intensively. Reconditioning helps to minimize distorted measurement readings during the calibration interval.

It is recommended to heat the measurement cell by choosing Manual after the cleaning or sterilization process or if distorted measurement readings are suspected.

To start heating, remove the housing cover and press the pushbutton S3 or trigger the ARC-module with the external signal (see Hardware, chapter 6.4 ARC-Module). The orange LED D3 is illuminated during heating.

8.3 Fuse replacement for option V01

If the green LED on the PCB is not flashing with the supply voltage switched on, check the fuse and replace if required.

Fuse secondary: 250mA / T UL248-14 Nominal voltage: 250V Replacement types: Series: MSTU 250 Manufacturer: Schurter Order No.: 0034.7109 Series: 374 Manufacturer: Littelfuse Order No.: 374 0250

performed using the EE33 software.

In addition to the manual calibration procedure on the circuit board (see

1-point calibration Humidity: Fast and easy calibration for accurate measurement results at a defined humidity

working point (e.g: 40...60% RH => 1 point calibration at 50% RH).

For calibration procedure see Hardware, chapter 7. “Humidity/Temperature Calibration”

1) Stabilise the probe of the desired humidity for min. 30 minutes.

2) Click on the Humidity "1-point calibration" button. The measured values will now appear in both input fields.

5.5 Parameter

Air pressure: If a transmitter of the EE33 series is operated far above sea level or a measurement is required at high process pressure, the prevailing ambient pressure can be entered to increase the accuracy of the derived values / computing functions.

Automatic ReCover (ARC): These input fields define the main heating para meters.

Heating time: Defines the time in which the monolithic measurement cell is intensively heated. A heating time of at least 20 minutes is recommended if chemical pollution has led to the presence of foreign molecules. A simple evaporation of temporary condensation, the default heating time of 10 seconds is sufficient.

Cool-down time: The cool-down time is the length of time the monolithic measurement cell is allowed to cool back down to the ambient temperature. The cool-down time should be >3 min. in order to prevent measurement errors.

Freezing period of outputs = heating time + cool-down time: During the complete heating and cool-down process, the 2 analog outputs are

frozen. In other words, the measuring values at the analog outputs are kept constant during the freezing period.

Start Automatic Recover (ARC): Heating can be started/triggered by various events.

Manual: Heating is started by choosing the S3 pushbutton on the PCB. A request should be made e.g. after chemical pollution (cleaning/sterilization) or when the measurement readings deviate significantly from comparable measurements.

External signal: To start the heating with external triggering, an (optional) ARC-module is required, see chapter Hardware 6.4.

Repetitive/time interval: A cycle time can be defined when the checkbox is flagged. Heating is started automatically and recurrent at the end of the cycle time. Periodic heating can be used to minimize any drifting of conventional capacitive humidity sensors caused by chemical pollution in applications. The ideal cycle time depends on the type of pollution and its concentration and has to be determined empirically.

Condensation/humidity: If the checkbox is flagged, a humidity set point > 90% RH (indicator for temporary condensation / dew) can be defined. If the set point is exceeded, heating is started automatically. Heating is automatically limited to 10 seconds. This time interval is sufficient to evaporate temporary condensation/dew.

Note: When heating has ended, the system blocks any subsequent heating for 30 minutes. In other words, if the ambient humidity remains above the defined set point after the initial heating, heating only begins again after 30 minutes.

This ensures that the transmitter once again displays measuring values that accurately reflect the humidity level of the environment no longer than approx. 3 minutes after temporary condensation.
