The proven MESSKO® TT PWM61 and TT-PWM62 temperature sensors contribute to the safe operation of power transformers. With the TT PWM61 and TT-PWM62 digital temperature transmitters, digital transmission is already integrated. Bus technologies enable the connection to control room systems for process monitoring. Unlike the TT-PWM61, the TT-PWM62 also features an analog thermometer – for reading off the temperature on site. Thanks to the PWM technology used, calibration to the selected output signal is no longer necessary.
