Product Details
ACD4100 Optical Refrigerant Sensor Infrared Detection Refrigerant
Leak Detection Module
- Operating Principle: The ACD4100 sensor is designed based on the
spectral absorption principle of R32 gas. It consists of three core
components: a precision light source, an efficient gas chamber, and
a high - sensitivity infrared receiver. The infrared rays emitted
by the light source interact with the refrigerant gas flowing
through the gas chamber, causing a change in the infrared light
absorption amount. This change is accurately captured by the
infrared receiver and converted into an electrical signal, and then
the concentration information of the refrigerant gas is analyzed
through a signal processing algorithm.
- Features:
- High - precision Measurement: Through precise measurement of the
absorbance of infrared light at a specific wavelength in the
refrigerant gas, combined with an advanced signal processing
algorithm, it achieves a high - precision monitoring accuracy of
±2.5%LFL.
- Wide Measurement Range: The wide - range design of 0 - 36000ppm can
meet the needs of detecting trace leaks to high - concentration
environments, ensuring the comprehensiveness and accuracy of
monitoring.
- Long Service Life: Thanks to the non - moving - parts design of
NDIR technology, the ACD4100 sensor has a service life of more than
15 years, which greatly reduces the maintenance and replacement
costs.
- Convenient Data Output: Equipped with a digital interface output,
it provides users with a convenient way to read data and interact,
which improves the user experience and system efficiency.
- Excellent Selectivity: It has excellent selectivity, no oxygen
dependence, and can stably detect the target refrigerant gas in a
complex environment.
- Application Scenarios: It is widely used in the refrigerant leakage
detection of large - scale industrial refrigeration equipment,
commercial refrigeration facilities such as supermarkets and cold
storage, and environmental protection monitoring stations,
providing a strong guarantee for the safe operation and energy -
efficiency optimization of refrigeration equipment.
