In order to make your life easier, a 4-SIP Module package includes this transducer. If you want reliable results, you should set the transducers' temperature to -40°C~85°C. Supply voltages as low as 2.5V~16V work well with the transducers. 4 pins must be connected in order for the transducer to work properly. A transducer of this type is capable of measuring pressures up to 250 Psi. For continuous operation of the transducers at ambient temperatures, DC voltage should be 10V.
