Thermometer construction
WebbConstruction of Thermometer Temperature Thermometers consist of three basic elements: spirit-filled liquid, which response to changes in heat and cold; a glass tube … These elements nearly always require insulated leads attached. PVC, silicone rubber or PTFE insulators are used at temperatures below about 250 °C. Above this, glass fibre or ceramic are used. The measuring point, and usually most of the leads, require a housing or protective sleeve, often made of a metal alloy that is chemically inert to the process being monitored. Selecting and designing protection sheaths can require more care than the actual sensor, as the sheath must …
