Transducers in 6-DIP Module are included for convenience. For reliable performance, set the temperature of the transducers to -40°C~85°C. Supply voltages of 20V are suitable for the transducers. A maximum temperature of 85°C can be reached by the transducers. Neither the transducers nor their operating temperature can be lower than -40°C. This can only be accomplished by connecting 6 pins to the transducers. To make the transducers work, the voltage released by them must be 90mV. Transducers should be able to operate continuously at their rated ambient temperatures if the DC voltage is 20V. The transducers can be subjected to voltages up to 20V without damage.
