Duct / Immersion Temperature Sensor
Active sensor (4...20 mA) for measuring
temperature in duct applications. In
combination with a stainless steel or brass
thermowell can also be used for pipe
applications. IP65 / NEMA 4X rated
enclosure.

Safety Notes
This device has been designed for use in stationary heating, ventilation and air-conditioning
systems and must not be used outside the specified field of application. Unauthorised
modifications are prohibited. The product must not be used in relation with any equipment
that in case of a failure may threaten humans, animals or assets.
Ensure all power is disconnected before installing. Do not connect to live/operating
equipment.
Only authorised specialists may carry out installation. All applicable legal or institutional
installation regulations must be complied during installation.
The device contains electrical and electronic components and must not be disposed of as
household refuse. All locally valid regulations and requirements must be observed.
Remarks
General Remarks Concerning Sensors When using lengthy connection wires (depending on the cross section used) the measuring
result might be falsified due to a voltage drop at the common GND-wire (caused by the
voltage current and the line resistance). In this case, 2 GND-wires must be wired to the
sensor - one for supply voltage and one for the measuring current.
Sensing devices with a transducer should always be operated in the middle of the
measuring range to avoid deviations at the measuring end points. The ambient temperature
of the transducer electronics should be kept constant. The transducers must be operated at
a constant supply voltage (±0.2 V). When switching the supply voltage on/off, onsite power
surges must be avoided.
Build-up of Self-Heating by Electrical Temperature sensors with electronic components always have a dissipative power which
Dissipative Power affects the temperature measurement of the ambient air. The dissipation in active
temperature sensors shows a linear increase with rising operating voltage. This dissipative
power should be taken into account when measuring temperature. As Belimo transducers
work with a variable operating voltage, only one operating voltage can be taken into
consideration, for reasons of production engineering. Transducers 0...10 V / 4...20 mA have
a standard setting at an operating voltage of DC 24 V. That means, that at this voltage, the
expected measuring error of the output signal will be the least. For other operating voltages,
the offset error will be increased by a changing power loss of the sensor electronics. If a re-
calibration should become necessary later directly on the sensor, this can be done by
means of a trimming potentiometer on the sensor board.
