3.2 Function description
The pointer thermometer measures the oil temperature or determines the
winding temperature in power transformers, distribution transformers or re-
actors, depending on the version. The sensor of the pointer thermometer is
located in the thermometer pocket mounted in the transformer tank. The
measured value is displayed directly on the pointer thermometer or, as an
option, on an analog or digital display using a signal converter.

16 Product description 9181336/00 EN
Depending on the device type, the electrical temperature signal can be trans-
mitted as follows:
–TT version: Connection via 4...20mA and/or 0...5VDC analog output
–Pt100 version: Connection via Pt 100 analog output

3.4 Versions
The pointer thermometer is available in the following versions:

20 Product description 9181336/00 EN
Oil temperature indicator
–Pointer thermometer with up to 6 independently configurable micro-
switches. With devices with 5 or 6 micro-switches, there are limitations in
terms of the number of change-over contacts; refer to the drawings in the
appendix.
–The temperature displayed is that of the oil temperature at the tempera-
ture sensor of the pointer thermometer.
–The mechanical measurement system functions independently and with-
out a power source.
Winding temperature indicator
–Pointer thermometer with up to 6 independently configurable micro-
switches. With devices with 5 or 6 micro-switches, there are limitations in
terms of the number of change-over contacts; refer to the drawings in the
appendix.
–The temperature displayed is that of the winding temperature based on
the oil temperature, secondary transformer current and the configured
temperature difference.
–The secondary transformer current is proportional to the current in the
winding.
–The secondary transformer current supplies a heating resistor in the me-
chanical pointer thermometer with power, thus causing a temperature in-
crease corresponding to the transformer load compared to the actual oil
temperature measured.
–The pointer thermometer with heating element is configured by adjusting
the heating current.
–The version with heating element and integrated MRB110-1 or MRB110-2
balancing resistor is configured via the resistor.
Optional versions
–TT version [►Section 3.4.1, Page 21]
