2. Design and function
2.1 Description
The model TR31 resistance thermometer consists of a thermowell with
a fixed process connection and is screwed directly into the process.
It is designed to be impact and vibration resistant and all electrical
components are protected against humidity (IP67 or IP69K). The
vibration resistance conforms to IEC 60751 (20 g, dependent on the
instrument version). The impact resistance of all versions meets the
requirements of IEC 60751.
