Flame Sensor RD-913FB1
Summary:
RD-913FB1 pyro-electric flame sensor uses lithium tantalate single crystal as the sensitive element material. The Curie temperature of lithium tantalate crystal material is above 600℃, the relative dielectric constant is small, and the specific detectivity is high.
Feature:
* 3.8um detection band;
* TO-5 package, single channel, voltage mode;
* Low microphone effect, large FOV, high detection rate;
* Detection band measurement of flame signal;
APPLICATION
The infrared alarm to prevent human intrusion is composed of pyroelectric infrared sensor and alarm controller. When someone enters the range to be protected, the sensor generates an electrical signal and transmits it to the controller, and the controller sends the alarm signal to the terminal through signal processing.
