EXG-500B High temperature combustible gas detector

Brief introduction

The EXG-500B high-temperature combustible gas detector, also known as the high-temperature resistant combustible gas leak alarm, is a fixed, LCD display high-temperature combustible gas detector independently developed for places where combustible gases are generated under high temperature conditions such as high-temperature furnaces and ovens. The product adopts a high-temperature combustible gas sensor imported from Japan. After research and testing, it has been found that it can be used in a high temperature environment of 250 degrees Celsius for one year without any damage, and still performs well in terms of accuracy and stability.

The signal defaults to 4-20mA current output and is compatible with systems such as PCL. 24V power supply, supporting 24-hour online monitoring. The product utilizes current microelectronic processing technology to quickly and accurately detect target gases. The product is designed with the highest level of three defenses for the gas detection industry: anti high concentration overload (with self-protection function), anti personnel misoperation (built-in buttons+can restore factory settings), and lightning protection (third level standard). Inherent safety circuit design, equipped with an aluminum alloy explosion-proof shell, can be safely used even in harsh environments.

The EXG-500B high-temperature combustible gas detector is a gas diffusion type. The detection principle is that when the target gas enters the gas probe section, the internal sensor will emit a sense of time. Sensors generate certain electrical signals based on the concentration of gas. After being amplified by the circuit, the signal is processed by the CPU through AD sampling, temperature compensation, and intelligent calculation to output accurate 4-20mA current signals, RS485 communication signals, 0-5V voltage signals, ZIGBEE, NRF, WIFI, GPRS wireless signals, etc. Customers can collect these signals andFuzhan Environmental ProtectionThe company'sBNC-800ABNC-800BBNC-800C gas alarm control host PLC、DCS、 The upper computer and other systems are used in conjunction for alarm and data reprocessing. In addition, the product is equipped with 2 sets of relays (switch signals) inside, which can be linked with the control equipment of the fan and solenoid valve to maximize the protection of your life and property safety.

The EXG-500B high-temperature combustible gas detector can also be equipped with sound and light alarm, infrared remote control, pipeline gas cup, pump suction gas cup, etc. according to customer needs.
