As a convenience, this transducer is included in Module. Temperature should be set at 0°C~70°C on transducers in order for them to work reliably. Obtaining a 7V~18V supply voltage is not a problem for the transducers. It is possible for the transducers to operate at a maximum temperature of 70°C. Temperatures below 0°C are unacceptable for the transducers. A nominal supply current of 27mA can run the transducers normally. If the transducer is designed to operate continuously at the rated ambient temperature, then the DC voltage should be 9V.
