Brief introduction

SGA-500E-C3H8O2Dimethoxymethane gas detectorAlso known as formaldehyde gas leak alarm, formaldehyde gas transmitter, or dimethyl ether gas detector; It is a fixed, non display type dimethoxymethane gas detector independently developed and produced by Shenzhen Guoan Electronics with more than ten years of technical experience; 24V industrial power supply, supporting 24-hour online monitoring; The product utilizes the most advanced microelectronics processing technology and is equipped with imported dimethoxymethane gas sensors from abroad, which can quickly and accurately detect target gases; Output RS485 signals based on ModBus communication protocol for customer convenience; When the on-site gas leakage reaches the preset alarm point, a local sound and light alarm of 85dB or above will be automatically issued to remind personnel to evacuate safely; One set of switch signals can also be optionally configured, which can be linked with equipment such as fans and shut-off valves to automatically handle dangerous situations; Inherent safety circuit design, equipped with an aluminum alloy explosion-proof shell, can be safely used even in harsh environments. With excellent quality, we have not only obtained the explosion-proof certificate (No. CNEx14.1674) issued by the national explosion-proof electrical department, but also obtained dual certifications of CE and ROHS from the European Union.

SGA-500E-C3H8O2Dimethoxymethane gas detectorThe default sampling method is gas diffusion, and it can be upgraded for free to specialized gas cups such as pump suction, pipeline, and circulation. The basic detection principle is that when the target gas enters the dedicated gas chamber of the gas detector, the internal gas sensor will immediately emit an induction. Sensors generate certain electrical signals based on the concentration of gas. shouldAfter the signal is amplified and processed by the circuit, the CPU outputs accurate 4-20mA current signals, RS485 communication signals, 0-5V voltage signals, ZIGBEE, NRF, WIFI, GPRS wireless signals, etc. through AD sampling, temperature and humidity compensation, and intelligent calculation. Customers can collect these signals and communicate with SGA, SGA-800B, SGA gas alarm controllers from Shenzhen Guoan Company PLC、DCS、 The upper computer and other systems are used in conjunction for alarm and data processing.

※ Precautions

1）We need to fully consider the issue of gas specific gravity: lighter than air should be installed at high places, and heavier than air should be installed at low places.

2）The closer the installation location is to the leakage source, the better
