The stem, the process connection and the case of the gas-actuated thermometers are made from stainless steel. To allow optimum fitting to the process, individual insertion lengths and process connections are available. The thermometers have a high ingress protection of IP65 and can be used in outdoor applications even at negative temperatures. With liquid damping operation under high vibration conditions is possible.
