Transmitter Applications
Power Stations Power generation, whether nuclear or fossil fuelled requires carefully controlled environments for best performance and reliability. |
HygroFlex offers the highest direct humidity measurement currently available. |
In combination with the HygroClip EX, the HygroFlex can be used to measure humidity and temperature in the most hazardous zone 0. |
||
Monitoring and control of any industrial drying process can have significant benefi ts in terms of product quality, energy use and productivity. |
|
Explosive materials such as weapons or chemicals also need to be kept at the correct humidity and temperature conditions. |
||
Every product from mobile telephones to a car is today subjected to thorough climatic test conditions to establish and maintain reliability. Humidity and temperature conditions are a critical part of this process. |
The measurement and control of the drying processes in the ceramics industry. |
Monitoring and control of the drying process. |
TRANSMITTERS
1. Measurement Accuracy:
Digital processing of
sensor signals provides much more scope and fl exibility for the compensation of error
components such as linearity and temperature coeffi cients.
ROTRONIC sensors have always
been regarded as amongst the most precise and stable in the world; with this new
technology, small errors become even smaller!
2. Maintenance and Calibration:
Digital signal communication allows components to be hot swapped without loss of measurement precision calibration and sensor data are retained permanently within each digital HygroClip probe.
HygroClip probes can be
hot swapped in seconds, signifi cantly reducing the maintenance and downtime
costs associated with the removal of instruments to laboratories or workshops for diffi
cult, time-consuming calibration and repair.
HygroFlex can also be field calibrated and adjusted directly using the HygroPalm 3 calibrator.
3. Precision and Stability:
Digital circuits are inherently more stable than analogue, and are less affected by temperature changes.
Calibration adjustment is
made purely by software, meaning no unstable, hard-to-reach potentiometers.
The option for
multiple calibration points is extended across the full measurement range.
4. Application Flexibility:
Measurement change? Need
dew-point instead of %rh? Or the mixing ratio ?
Simply connect the HygroFlex to a PC and
change the configuration!
Different installation? If your application needs change, simply fi t one of the wide range of probes with an alternative confi guration or temperature operating range.
Multiple point
measurement?
Need to expand?
The HW3 software package offers a comprehensive networking
solution for up to 32 instruments.
HW3 features data logging (reporting), graphical and
alarm functions and operates on any standard Windows based PC.
Wiring hardly possible? Or too expensive? The HygroFlex is able to communicate by means of a radio controlled interface option.
5. Measurement of Dew Point and other Parameters:
Digital technology makes
it possible to obtain parameters such as dew point or the mixing ratio with economical,
versatile and easy-to-maintain instruments and probes.
Taking the chilled mirror
technology as an example, typical requirements and problems are eliminated: no sampling
system is required in most applications, there is no longer any uncertainty between dew
and frost, and the requirement for frequent mirror cleaning fully disappears.

Precise factory adjustment and superb
long term stability provide consistent measurement results with minimum maintenance.
Analogue outputs
HygroFlex 1 accepts one
HygroClip probe and provides two linear analogue outputs for relative humidity and
temperature.
Standard factory confi guration is 4
20 mA, but this can be easily
changed to 0
20 mA, 0
1 V, 0
5 V or 10 V.
Scaling of the output range can
be modifi ed from the standard 0
100 % rh and 0
100 °C using the internal
service connection, connecting cable AC1623 and a PC running the HW3 software.
Key features:

Interchangeable probes
Two linear analogue outputs
Jumper confi guration of analogue outputs
One probe input, digital or analogue (0 2.5 V, 10 Bit A/D; 12 Bit interpolated) Optional display/keypad
An external test socket is
standard.
A HygroPalm 3 handheld instrument can be connected to provide a live display of
the transmitters current measurement values.
When connected, the HygroPalm 3 can also be
used as a digital adjustment tool for any probe connected to the HygroFlex 1.
The optional display & keypad gives a local display of measurement values and provides access to the 1 or 4 point probe adjustment directly from the HygroFlex 1 transmitter.

Simultaneous Analogue and Digital Outputs with Absolute Humidity Calculation
HygroFlex 3 combines all the features of the HygroFlex 1 and 2 into a highly specifi ed instrument, and represents probably the most advanced humidity and temperature transmitter on the market. Additional features include a third analogue output for greater fl exibility, a simultaneous serial output and the ability to dynamically compensate calculated humidity parameters for variations in application pressure.
The comprehensive range of outputs available makes the HygroFlex 3 particularly well suited to combined monitoring and control applications. The analogue outputs can be connected to the applications control system, whilst the digital RS232 signal interfaces with a local PC where engineers can monitor the process and set up alarms via Email or SMS text messages.
The dynamic pressure compensation feature is truly state of the art. In climatic test or research and development projects, the humidity measurements can be optimised for any condition with the inclusion of pressure measurement, and therefore compensation of pressure dependent calculated values such as enthalpy and wet-bulb temperature. All calculated parameters are based on WMO formulae.

HygroClip EX Digital EX Humidity and Temperature Measurement
HygroClip EX is a series
of probes for the measurement of humidity and temperature in hazardous areas featuring the
latest digital signal processing and data transmission technology.
Suitable for connection
to the HygroFlex range of industrial transmitters, or for use as a stand alone 4
20
mA 2 wire transmitter, the HygroClip EX probes offer wide measurement ranges and fl exible
