2. Design and function
2.1 Description
The transmitters described are equipped with sensors for pressure, temperature and
humidity (only model GDHT-20). From this, the integrated microprocessor electronics,
with the help of algorithms, calculate the status parameters of SF
moisture (only model GDHT-20).
2.2 Scope of delivery
Cross-check scope of delivery with delivery note.
3. Safety
3.1 Explanation of symbols
WARNING!
... indicates a potentially dangerous situation that can result in serious
injury or death, if not avoided.
CAUTION!
... indicates a potentially dangerous situation that can result in light injuries
or damage to property or the environment, if not avoided.
Information
... points out useful tips, recommendations and information for efficient
and trouble-free operation.
3.2 Intended use
WARNING!
Before installation, commissioning and operation, ensure that the appropri-
ate transmitter in terms of measuring range, design and specific measuring
conditions, has been selected.
Non-observance can result in serious injury and/or damage to property.
Further important safety instructions can be found in the individual
chapters of these operating instructions.
These transmitters are designed for use on systems filled with SF
ting gas. There, the state variables pressure, temperature and humidity (only model
GDHT-20) are measured permanently. From these, the transmitter calculates the values
gas density and dew point/frost point information of the gas in order to evaluate the
WIKA operating instructions transmitter, models GDT-20 and GDHT-20
gas for gas density and
