1 Safety notes
Safe and secure operation of the head transmitter can only be guaranteed if the operating
instructions and all safety notes are read, understood and followed.
1.1 Designated use
• The unit is a universal, presettable temperature head transmitter for resistance temperature
detectors (RTD), thermocouple (TC) as well as resistance and voltage sensors. The unit is
constructed for mounting in a connection head (DIN form B) or field housing.
• The manufacturer cannot be held responsible for damage caused by misuse of the unit.
• Separate Ex documentation is part of this operating manual, for measurement systems in
hazardous areas. The installation conditions and connection values indicated in these instructions
must be followed!
1.2 Installation, commissioning and operation
The unit is constructed using the most up-to-date production equipment and complies to the safety
requirements of the local guidelines. The temperature transmitter is fully factory tested according to
the specifications indicated on the order. However, if it is installed incorrectly or is misused, certain
application dangers can occur. Installation, wiring and maintenance of the unit must only be done
by trained, skilled personnel who are authorized to do so by the plant operator. This skilled staff
must have read and understood these instructions and must follow them to the letter. The plant
operator must make sure that the measurement system has been correctly wired to the connection
schematics.
Electrical temperature sensors such as RTD's and thermocouples produce low-level signals
proportional to their sensed temperature. The temperature transmitter converts the low-level sensor
signal to a standard 4 to 20 mA DC signal that is relatively insensitive to lead length and electrical
noise. This current signal is then transmitted to the control room via two wires.
The transmitter needs to be commissioned before installation in a hazardous area. Configuration of
the device in explosion area is not allowed. Make sure the instruments in the loop are installed in
accordance with intrinsically safe or non-incendive field wiring practices before connecting in an
explosive atmosphere.
The transmitter electronics module is permanently sealed within the housing, resisting moisture and
corrosive damage. Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
#Warning!
Electrical shock could cause death or serious injury. If the sensor is installed in a high voltage
environment and a fault or installation error occurs, high voltage may be present on the transmitter
leads and terminals.
Temperature Effects
The transmitter will operate within specifications for ambient temperatures between -40 and 185 °F
(-40 and 85 °C). Heat from the process is transferred from the thermowell to the transmitter
housing. If the expected process temperature is near or beyond specification limits, consider the use
of additional thermowell lagging, and extension nipple, or a remote mounting configuration to
isolate the transmitter from the process.
