The Transducer 6-DIP 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 20V supply voltage. 85°C is the maximum operating temperature of the transducers. It is not possible for the transducers to operate at temperatures lower than -40°C. In order for the transducers to function properly, the 6 pins must be connected. This device must work at 100mV voltage from the transducers. In order to keep the transducers at the temperature they are rated for, the DC voltage needs to be 20V. The transducers are capable of handling a maximum voltage of 20V.
