Product overview
YA-D400 series point type gas detectors are widely used in
chemical, petroleum, metallurgy, liquefied gas stations, painting
operations, gas transmission and distribution and other toxic,
combustible gas generation, storage, use and other indoor and
outdoor easy to leak gas dangerous places.
YA-D400 series point type gas detector is a practical and easy to
operate gas detector developed by our company. It can be combined
with our gas alarm controller YA-K series to form an industrial gas
alarm system.The product adopts wall-mounted (can also hold the
tube type, scaffolding type, ceiling type) installation, through
the use of the controller, and through the controller single chip
microcomputer to upload the data of the gas detector for a variety
of data processing, and finally complete the data display, output
control and other functions.
YA-K300 series gas alarm controllers can be combined with our YA-D
series gas detectors to form industrial gas control systems. The
product is a gas detection and early warning system designed for
industrial environment. 4.3-inch industrial LCD display mode, clear
and eye-catching to achieve the concentration of gas to be measured
display, after the concentration exceeds the audible and visual
alarm; The product is also equipped with a number of output relays,
which can drive the exhaust fan, solenoid valve and other equipment
in active and passive ways to adapt to different field conditions;
Its design follows the national standard, has the advantages of
fast response speed, high reliability, low failure rate, easy
maintenance and so on. Especially in the judgment of alarm failure,
the method of multiple event delay confirmation is used to
effectively prevent false alarms and provide a strong guarantee for
people's life and property safety.
The product adopts wall-mounted installation, through the
cooperation with the detector, and through the controller
single-chip microcomputer to upload the data of the gas detector
for a variety of data processing, and finally complete the data
display, output control and other functions.
