Product Description:
The YA-D400 series point type gas detectors are a widely used
solution for detecting toxic and combustible gas at various indoor
and outdoor locations where gas leakages can occur. These detectors
are commonly utilized in chemical, petroleum, metallurgy, liquefied
gas stations, gas transmission and distribution facilities, and
painting operations.
Developed by our company, the YA-D400 series point type gas
detector is a practical and easy-to-use gas detector that can be
seamlessly integrated with our gas alarm controller YA-K series, to
create an industrial gas alarm system. This product supports
wall-mounted installation, and also holds versatility to be
installed using tube type, scaffolding type, and ceiling type
mechanisms.
This gas detector functions by uploading its data to the
controller, which uses a single chip microcomputer for a variety of
data processing tasks. The processed data is then displayed on the
controller along with control outputs, thus providing an effective
and robust gas detection solution.
Features:
Below are some features of the gas detector:
- Displays the concentration of the detected gas.
- Includes fault alarm, high and low alarm.
- Provides field screen display that includes backlight with larger
and clearer words. The backlight turns red when the device alarms.
- Equipped with infrared remote control input for more convenient
operation without open cover.
- Supports three different sound and light outputs that correspond to
fault, low report, high report.
- Zero, calibrate, test function available.
- Can output DC4-20mA standard signal.
- Offers flexible communication mode through support for RS485, two
buses, and LoRa.
- Integration of a high-performance ARM microprocessor facilitates
easy operation.
- Includes three relay (250V 5A) output that automatically opens the
fan and solenoid valve.
- Has the capability to store 40 high and low alarm records.
- Toxic gas detector can achieve mg/m³ and μmol/mol conversion.
