UV Flame sensor is fire detect sensor which detecs ultraviolet rays of a flame instantly and output warning signal outside. By using emergency call equipment or adjusting the sensor connection, SKH-)$& can supervise multiple sensors at a long range.
Our most advanced intelligent spot detectors, multi-criteria/multi-sensor devices use multiple sensors to detect various conditions in an environment sensing a wider range of fires with greater accuracy.
Features & Benefits:
Multi-Criteria/Multi-Sensor smoke detection
Unique ability to detect major elements of a fire
Highest nuisance alarm immunity
Advanced algorithms interpret and respond to multiple inputs

Gallium nitride based material
Schottky-type photodiode
Photovoltaic mode operation
Good visible blindness
High responsivity & low dark current
PCFS-IR2125A level sensor contact type, it is used for tube. The principle is infrared, output signal is analog. When there is no water, the sensor outputs low voltage value; When there is water, the sensor outputs a high voltage signal. The size can be customized. The photoelectric liquid level switch has high precision, low price, high reliability and wide application environment, it is less affected by strong acid, alkali and viscosity. Photoelectric level sensors can be used for higher liquid level accuracy requirements.

About the material silicon carbide (sic)
Sic provides the unique property of extreme radiation hardness, near-perfect visible blindness, low dark current, high speed and low noise. These features make sic the best available material for visible blind semiconductor uv detectors. The sic detectors can be permanently operated at up to 170°c (338°f). The temperature coefficient of signal responsivity) is also low, < 0, 1%/k. Because of the low noise (dark current in the fa range), very low uv radiation intensities can be measured reliably. Please note that this device needs an appropriate amplifier (see typical circuit on page 3).
Options
Sic photodiodes are available with seven different active chip areas from 0, 06 mm2 up to 36 mm2. Standard versionis broadband uva-uvb-uvc. Four filtered versions lead to a tighter sensitivity range. All photodiodes have a hermetically sealed metal housing (to type), either a 5, 5 mm diameter to18 housing or a 9, 2 mm to5 housing. Further option is either a 2 pin header (1 isolated, 1 grounded) or a 3 pin header (2 isolated, 1 grounded).
