6-SIP Module includes this transducer for convenience. Reliable performance can be assured by setting the transducers to -40°C~85°C. A supply voltage of 20V is sufficient for the transducers to operate well. It is possible to reach the maximum operating temperature of the transducers 85°C. Temperatures of the transducers cannot be below -40°C. To make the transducers work, you must connect the pins at 6. Transducers must release 100mV voltage to work. The transducers should operate continuously at ambient temperature by using DC voltage of 20V. The transducers can withstand a voltage of 20V.
