Transducers in 4-SIP Module are included for convenience. For reliable performance, set the temperature of the transducers to -40°C~85°C. Supply voltages of 2.5V~16V are suitable for the transducers. This can only be accomplished by connecting 4 pins to the transducers. 100 Psi is the maximum pressure range set by this transducer. To make the transducers work, the voltage released by them must be 100mV. Transducers should be able to operate continuously at their rated ambient temperatures if the DC voltage is 10V.
