EMCO's TEM platinum resistance temperature sensors measure process fluid temperature for most applications. The TEM transmitter uses a resistance temperature device (RTD) to measure process temperature. RTDs operate on the principle that the resistance of the sensing device is proportional to the temperature, producing a highly repeatable and exceptionally stable resistance versus temperature relationship. The TEM transmitter may be selected with either a direct RTD output or with an industry standard 4 to 20 mA current output. The current output includes a preamplifier that is factory scaled and calibrated to one of several standard temperature ranges in either Fahrenheit or Celsius. The TEM is a thermowell mounted to allow installation and removal without process shutdown. Several immersion lengths are available to accommodate a wide range of pipe sizes.
