RD-913FB4 Pyro-electric Flame sensor
|Detection principle:||pyroelectric effect|
|Characteristics:||1、4.4um detection band;2、TO-5 package,single channel,voltage mode;3、Low microphone effect,large FOV,high detection rate;4、Detection band measurement of flame signal|
|Notes:||This product has been discontinued and replaced by RPFA913CF|
RD-913FB4 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.
- 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.
- 4.4um detection band;
- TO-5 package, single channel, voltage mode;
- Low microphone effect, large FOV, high detection rate;
- Detection band measurement of flame signal;

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with UL, CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to email@example.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
