Specification
The model 55 bimetal thermometer has been developed and is manufactured in accordance with the EN 13190 standard. This high-quality thermometer has been designed especially for the requirements of the process industry. Especially in the chemical and petrochemical, oil and gas, and power engineering industries, the temperature measuring instrument completely manufactured from stainless steel is used successfully.
The model 55 satisfies the high requirements for resistance against aggressive media. As an option, the case can be made from 316L to fulfil the highest requirements.
To allow optimum fitting to the process, individual insertion lengths and different process connections can be selected.
When it comes to harsh climatic conditions at the place of use, the model 55 is the right choice, as it can be used at temperatures ranging from -40 °C [-40 °F] to +70 °C [+158 °F] (optionally also up to -50 °C [-58 °F] or -70 °C [-94 °F] in the POLARgauge® version).
