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.

Application

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 community, commercial buildings,public sites and general industrial fields.

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;
