This transducer is included in the package Cylinder for your convenience. For reliable performance, the transducers should be set to -20°C~85°C. The transducers are capable of operating with a supply voltage of 2.5V~12V. Transducers should release a voltage of 100mV in order for them to function. For the transducers to operate continuously at ambient temperatures, the DC voltage should be set to 5V.
