As a convenience, the transducer is included in the package 4-SIP Module. Ensure reliable performance by setting the transducers to -40°C~85°C. With a supply voltage of 2.5V~16V, the transducers can operate efficiently. The transducers are not able to work properly without the 4 pins being connected. To make the transducers work, the voltage released should be 16.7mV. Transducers should operate continuously at their rated ambient temperature if the DC voltage is set to 10V.
