As a convenience, this transducer is included in 6-SIP Module. Temperature should be set at -40°C~85°C on transducers in order for them to work reliably. Obtaining a 20V supply voltage is not a problem for the transducers. It is possible for the transducers to operate at a maximum temperature of 85°C. Temperatures below -40°C are unacceptable for the transducers. To ensure proper operation of the transducers, it is necessary to connect the 6 pins. In order for the transducers to work, the voltage discharged by them should be 90mV. If the transducer is designed to operate continuously at the rated ambient temperature, then the DC voltage should be 20V. You can apply a voltage of 20V without damaging the transducers.
