weld-in thermometer

The thermometers measure temperatures of gaseous or liquid media in pipes and containers. The immersion part in contact with the medium (the sensor tube or additional protection tube) is fixed to the process by a welding element (e.g. weld-in protection tube, weld-in ball or weld-in cylinder).
Variants for particularly pressure-loaded applications are possible.
