Vibration resistance at the sensor tip
■ Resistance thermometer
6 g peak-to-peak, wire-wound measuring resistor or metal thin film (standard)
20 g peak-to-peak, wire-wound measuring resistor or metal thin film (option)
50 g peak-to-peak, metal thin film measuring resistor (option) 1)
1) For measuring insert diameter < 8 mm
■ 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 certified transmitters. Optionally, separately certified
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 flow 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.
