VT
Type P10-VA2
Description： The VT P10-VA2 flame detector is based on the pyroelectric effect of lithium tantalate single crystal, with ultra-low noise field effect transistor and silicon substrate narrowband.
Filters ensure high detector response rate and low noise.
This type of detector is suitable for small and medium-sized spaces such as rooms and containers within the flame detection and converted into a corresponding voltage signal output。
Features： 1.High single channel
2.Quick response
3.Small and medium space detection
4.Cost-effective

◆Precautions
1.The operating environment of the detector should be kept clean and tidy, and avoid
touching the filter directly with hands and hard objects.
2.During the welding process, it is recommended to leave a distance of more than 4mm
between the detector base and the circuit board, and the welding time should be as short as possible.
3.Pay attention to electrostatic protection during the use of the detector.
