YA-D400 series point type gas detectors are essential tools for detecting toxic and combustible gases in hazardous environments. They are widely applied in various industries, such as chemical, petroleum, metallurgy, liquefied gas stations, painting operations, gas transmission and distribution.
Our company has developed YA-D400 series point type gas detectors, which are practical and easy to operate. They can be conveniently combined with our gasalarm controller YA-K series to form an industrial gas alarm system.
The product is designed for wall-mounted installation, but it can also hold the tube type, scaffolding type, or ceiling type for flexible deployment. By using the controller, the gas detector data can be uploaded for a variety of data processing, and the controller's single chip microcomputer can display and output control the functions.
The gas detector has the capability to display the concentration of the gas that it detects. This provides users with a quick and easy way to determine the amount of gas present.
If there is a fault or an issue with the gas detector, it will emit a fault alarm. Additionally, the device is equipped with both a high and low-level alarm.
For easy viewing, the field screen display features a backlight, making the information on the screen bright and clear. The backlight will turn red when there is an alarm, providing a visible warning to users.
Infrared remote control input allows users to operate the device without the need to open it. This feature adds convenience to the system.
The gas detector is also equipped with three different sound and light output indicators for fault, low report, and high report. These indicators alert users when levels of the detected gas are outside of acceptable levels.
Additional functions of the gas detector include the ability to zero, calibrate, and conduct tests. The device also outputs a DC4-20mA standard signal.
The gas detector supports multiple communication modes such as RS485, two buses, and LoRa. This allows for flexibility in how the system communicates.
The high-performance ARM microprocessor aids in easy operation of the gas detector. With this processor, users can easily navigate the device's interface and access its functions.
Other features include three relay (250V 5A) outputs, which can automatically open the fan and solenoid valve when necessary. Additionally, the gas detector can store up to 40 high and low alarm records. Lastly, the toxic gas detector is capable of achieving mg/m³ and μmol/mol conversion, providing users with different options for reading units.
