YA-D400 series point type gas detectors are widely used in various industries with potential gas leakage hazards, such as chemical, petroleum, metallurgy, liquefied gas stations, painting operations, gas transmission, and distribution. The gas detector is a practical and easy to operate device that has been 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 installation but can also hold the tube type, scaffolding type, and ceiling type.

The gas detector with the gas alarm controller single chip microcomputer uploads the data of the gas detector for a variety of data processing, and finally, complete the data display, output control, and other functions. The gas detector has a variety of applications and is a vital safety device in hazardous environments.

The YA-K300 series gas alarm controllers can be combined with our YA-D series gas detectors to form industrial gas control systems. It is designed for an industrial environment and is a detection and early warning system for gas leaks. The product has a 4.3-inch industrial LCD display mode, clear, and eye-catching measurement display, and generates an audible and visual alarm when the concentration of gas exceeds the safe limit.

The gas alarm controller is equipped with a number of output relays that can drive the exhaust fan, solenoid valve, and other equipment in active and passive ways. This feature enables it to adapt to different field conditions and ensure people's life and property safety. Its design follows the national standard and has the advantages of fast response speed, high reliability, low failure rate, and easy maintenance.

The gas alarm controller uses a unique method of multiple event delay confirmation to prevent false alarms, making it highly effective in critical alarm situations.

The D400 Gas Detector is a reliable device that displays the concentration of the detected gas. It comes with a fault alarm as well as high and low alarm features for added convenience.

The device also features a field screen display that comes with a backlight, making it easier to read and providing clearer readings. To alert users when a gas is detected, the backlight turns red.

With an infrared remote control input, the D400 Gas Detector eliminates the need for open cover operation, making it a more convenient option. It also supports three different sound and light output settings that correspond to different levels of gas detection.

In addition, the D400 Gas Detector comes with a zero, calibrate, and test function. It outputs a DC4-20mA standard signal and supports RS485, two buses, LoRa, and flexible communication modes. The device also boasts a high-performance ARM microprocessor for easy operation. It has three relay (250V 5A) outputs that can automatically open the fan and solenoid valve. Furthermore, the D400 Gas Detector can store 40 high and low alarm records and can also achieve mg/m³ and μmol/mol conversion for toxic gas detection.

The K300 Gas Alarm Controller is an intelligent system that is equipped with a host embedded microprocessor and rich software functions. It can perform complete detector signal sampling, data real-time calculation, system fault detection, power management, key scanning, display driver, alarm display, alarm peripheral driver, and other functions.

With an intelligent system, the K300 Gas Alarm Controller supports %LEL,PPM,mg/m³,ug/m³,%VOL and other units, making it a versatile option for different applications.

The K300 Gas Alarm Controller features two sets of common relays and 8 sets of programmable relays with passive outputs for easy connection to various external devices. It also supports 4-20mA and 485 bus two communication modes, making it easy to install and use.

The K300 Gas Alarm Controller allows for real-time monitoring of the measured gas concentration in the detection area. When the gas concentration reaches or exceeds the set alarm value, the controller will issue sound, light, voice broadcast alarm signals to alert users of the danger.

The device also features a monitoring system for failure and fault acoustic and optical alarm functions. When the preset logic relationship is satisfied, the connected external device can act on its own. External devices can be started through the controller, and more than 2000 data records can be stored for future reference.
