The Model PTED EMF- and RTD-to-Pneumatic Converters receive and input, such as mV DC, thermocouple, RTD or 1 to 5 V DC and converts it to a 20 to 100 k Pa pneumatic pressure. For temperature measurements, a built-in linearizer inearizes temperature vs. Pneumatic output signal. A burnout circuit can be provided for thermocouple, RTD and mV DC inputs.
