Product Details
T15770 Infrared photoelectric sensor
Uses:
- Flame Detection: It is mainly used to detect the infrared radiation
of flames. It has a fast response to the specific wavelength of
4.45 μm in the flame spectrum, which can effectively identify the
presence of flames and is widely used in fire - fighting equipment
and safety monitoring systems.
- Industrial Automation: In industrial production processes, it can
be used to monitor the combustion state of furnaces or detect the
presence of flames in some high - temperature processes to ensure
the normal progress of production and the safety of equipment.
- Environmental Monitoring: It can be used to detect wildfires or
monitor the combustion of some harmful substances in the
environment to provide data support for environmental protection
and disaster prevention.
Characteristics:
- High Sensitivity: It has a high - sensitivity photosensitive
element, which can detect very weak light signals, enabling it to
quickly respond to the weak infrared radiation of flames, even in
low - light or complex backgrounds.
- Fast Response: With a typical rise time of 20 ms and a maximum of
30 ms, it can quickly detect the sudden appearance of flames and
convert the optical signal into an electrical signal for rapid
transmission and processing, which is crucial for timely fire alarm
and safety protection.
- Narrow - Band Spectral Response: The spectral response is centered
at 4.45 μm, which has strong selectivity for the infrared
wavelength of the flame. It can effectively avoid interference from
other wavelengths of light, improve the accuracy of flame
detection, and reduce false alarms.
- Good Stability: It has good stability in a certain temperature
range (- 20 °C - 50 °C) and humidity range (15% - 90% RH), with a
small temperature coefficient of element resistance. It can work
stably for a long time and is less affected by environmental
factors, ensuring the reliability of detection results.
- Compact Structure: Housed in a TO - 18 metal package, it has a
small volume and is easy to install and integrate into various
detection systems, which is convenient for use in different
application scenarios such as fire - fighting equipment and
industrial detection.
