The Transducer 4-SIP Module is included in the package for convenience. It is recommended to set the temperature of the transducers to -40°C~85°C to ensure reliable operation. The transducers are capable of operating well at 10V~12V supply voltage. In order for the transducers to function properly, the 4 pins must be connected. This transducer can handle pressures up to 15 Psi. If the nominal supply current is 2mA, the transducers will operate normally. This device must work at 285mV voltage from the transducers. In order to keep the transducers at the temperature they are rated for, the DC voltage needs to be 10V.
