This series of thermometers is universally suitable for the machinery, plant and apparatus construction. Gas actuated thermometers with capillary are used in locations which are not easily accessible and where  long distances have to be bridged. The stem, the process connection and the case of the instrument 1) are made from stainless steel. Various insertion lengths and process connections are available to optimally match the requirements of each  process. The thermometers have a high ingress protection of IP 65 and can be used in outdoor applications even at minus temperatures. With liquid damping they are suitable for use under high-vibration conditions. Due to the wide variety of possible designs the Model 73 gas actuated thermometers can be perfectly adapted to any process connection and location. For instance the adjustable stem and dial version can be adjusted to almost any angle to allow easy reading, and with the version with contact bulb temperature measurements are possible without any contact to the medium, even when the pipe diameter is extremely small. The contact bulb is intended for external mounting on pipes and tanks. When mounting thisthermometer version, it has to be ensured that the contact bulb is in contact with the measuring point over its complete length.
