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 10V~12V 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 30 Psi. In the case of nominal supply current 2mA, the transducers can operate normally. If it is to work, the transducers' voltage should be 330mV. For continuous operation of the transducers at ambient temperatures, DC voltage should be 10V.
