Analogue three-wire transducer for mounting rail. The transmitter, intended for industrial use, records the temperature with a resistance thermometer. The output signal is available in a temperature-linear fashion. The fully analog signal path enables extremely fast response times of the output at the temperature change (analog time measurement instead of digital measuring rate). This results in a low-noise and noise-immune output signal. Highest precision - even with small measuring range - is guaranteed by the measuring range-specific reinforcement. Digital communication allows the transmitter to be adapted to the measurement task (measuring range, probe breakage and fine calibration).This text is machine translated.
