The Thermophant T TTR31 is a temperature switch for the monitoring, display and control of process temperatures and is available with a wide range of process connections.
A platinum sensor located at the measuring tip changes its resistance value depending on the temperature. This resistance value is recorded electronically. The conversion of the resistance value into a temperature measurement signal is defined by the international standard IEC 751.
