TT temperature transmitters are used in commercial and industrial processes for air, gas and fluid temperature measurement in rooms, pipes, tanks, ducts, etc. All the transmitters detect the temperature value to be measured by means of a semiconductor sensing element, whose signal, suitably linearized and amplified, is transformed into a voltage (0...10 V-) or current (4...20mA) output signal. Maximum temperature range of the TT line is -50°C -  +100°C.
