Resistance thermometer

6 g peak-to-peak, wire-wound measuring resistor or metal thin lm (standard)

20 g peak-to-peak, wire-wound measuring resistor or metal thin lm (option)

50 g peak-to-peak, metal thin lm measuring resistor (option)

Thermocouples

50 g, peak-to-peak

Electrical connection

On the connection side, the thermometer has a housing or bare wire ends. The housing

design will contain the terminals or certied transmitters. Optionally, separately certied

digital displays can be built into the housing.

The connection side of the measuring insert consists of a transition sleeve with connected

connection wires.

CAUTION!

Thermometers of this model range must when used in zone 0 be installed with a

thermowell (minimal wall thickness: 1 mm) The design of the thermowell can be

selected as desired, but the operational process data (temperature, pressure,

density and ow rate) must be taken into account.

Possible sensor measuring ranges:

Model TR12: -200 ... +600 °C

Model TC12: -40 ... +1,200 °C

The following mounting and operating information has been compiled with care.

However, it is not possible to consider all potential applications.
