4-SIP Module includes this transducer for convenience. Reliable performance can be assured by setting the transducers to -40°C~85°C. A supply voltage of 2.5V~16V is sufficient for the transducers to operate well. To make the transducers work, you must connect the pins at 4. 30 Psi is the transducer's maximum pressure range. Transducers must release 100mV voltage to work.
