As a convenience, the transducer is included in package Cylinder. Reliable performance is ensured by setting the transducer temperature to -40°C~125°C. With a voltage supply of 10V, the transducers can function properly. The transducers can operate at a temperature of 125°C. An operating temperature lower than -40°C is not allowed for the transducers. In order for it to work, the voltage released by the transducers must be 100mV.
