| Thermowell / Protection tube | In principle, the operation of a mechanical thermometer without a thermowell / protection tube is possible with low process-side loads (low pressure, low viscosity and low flow rates). However, in order to enable exchanging the thermometer during operation (e.g. instrument replacement or calibration) and to ensure a better protection of the measuring instrument and also the plant and the environment, it is advisable to use a thermowell / protection tube from the extensiveWIKA thermowell / protection tube portfolio. |  |
