The 4-SMD Module package includes this transducer for convenience. In order to ensure reliable performance, the transducers should be set to -40°C~85°C. With a supply voltage of 2.5V~12V, the transducers can operate well. In order to make the transducers work properly, the 4 pins must be connected. This transducer has a maximum pressure range of 15 Psi. For it to work, the transducers should release 225mV voltage. To keep the transducers operating continuously at rated ambient temperatures, the DC voltage should be 10V.
