A novel temperature detector, known as Matthey Thermafilm, has been developed. It consists essentially of a platinum film firmly bonded to a ceramic substrate. The film is protected from the possible corrosive effects of gaseous environments by an overglaze of impervious, electrically insulating glass, forming a device that is mechanically and thermally robust. Since the sensing unit generally does not require further protection by encapsulation in a metal or ceramic sheath, it responds very rapidly to thermal changes. The construction of the detector renders it eminently suitable for monitoring transient thermal changes in most environments.
