Zhengzhou Winsen Electronics Technology Co., Ltd www.winsen-sensor.com RPFA913CF Pyro-electric Flame sensor RPFA913CF 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. In a wide range of room temperature, the pyroelectric coefficient of the material changes very little with temperature, and the temperature change rate of the output signal is only 1-2. The temperature stability of the sensor performance is very good, and the spectral response consistency is very good in the wavelength range of 1-20um. Features: * 4.48um detection band; * TO-5 package, single channel, voltage mode; * Low microphone effect, large FOV, high detection rate; * Detection band measurement of flame signal; Applications: It's widely used in various oil storage stations, large warehouses, factory workshops, forests, charging piles; and standard configuration for high fire risk areas such as petroleum, chemical, paper-making, forests, and garages. It also becomes popular in high-end residential, commercial, and general industrial fields.

When using pyroelectric infrared sensors, proper shock absorption and shielding are necessary. (2) In order to avoid turbulent air flow and crosstalk, which may cause false alarms, when the sensor is used in the design of the flame detector, window protection (such as white sapphire, calcium fluoride or infrared glass, etc.) must be added. (3) When welding the pyroelectric infrared sensor, it is recommended to solder at a position above 3mm. When using a soldering iron for manual soldering, the temperature of the soldering iron tip should be controlled below 350, and the soldering time for each location is less than 3 seconds, and the tube should be clamped with tweezers, to prevent damage to the electronic components under high temperature conditions. (4) During the installation and use of the pyroelectric infrared sensor, prevent the sensor components from falling. The sensor should be stored in a dry environment. (5) When operating the pyroelectric infrared sensor, the temperature of the pyroelectric infrared sensor is changed due to hand contact, especially through welding. Therefore, when the sensor is working again, it is necessary to wait for a period of time. After the temperature of the sensor is balanced, resume normal work. (6) Do not touch the sensor window directly with your hands and hard objects. Keep the window clean. When there is dirt, use an alcohol cotton ball to gently wipe it clean. (7) When installing the sensor, it is forbidden to apply mechanical pressure to prevent damage to the sensor's sensitive elements, windows and other components due to the existence of pressure. (8) When the sensor is taken out from the packaging box, and during measuring and installing, it must be equipped with electrostatic protection tools. The electrostatic protection requirement is less than 2000V to prevent the high voltage from breaking down the field effect tube of the sensor.
