Gas detector（Part One）

ZWIN-GasGuard06 Combustible Gas Detection Alarm

    

Product Introduction

The Combustible Gas Detection Alarm has the functions of on-site detection concentration display, signal transmission, LED light and relay alarm. The device supports the detection of gas concentrations such as TVOC (total volatile organic compounds), methane and ammonia, and converts the gas concentrations detected on-site into corresponding standard signals, and then transmits the signals to the host computer, such as PLC, DCS, and alarm control host, for unified display, management and control. The detector with display is equipped with a relay (switch signal) inside, which can control equipment such as fans, sound and light alarms, and solenoid valves. It has Internet of Things functions such as remote monitoring, mobile phone/computer alarm prompts, and alarm value settings. It can be used in chemical, gas, pharmaceutical, metallurgical and other industries to monitor combustible gases such as methane and ammonia. It can also be used in environmental monitoring and scientific research to monitor the concentration of harmful gases such as VOCs in the atmosphere.

ZWIN-GasGuard06-CO Gas Detection Alarm

Product Introduction

The CO Gas Detection Alarm uses a highly reliable operational amplifier and intelligent chip, an explosion-proof housing design, and a remote adjustment method (infrared remote control). It can convert the concentration of toxic and harmful gases monitored on site into a digital signal output of the standard MODBUS/RS-485 communication protocol and a 4-20mA standard analog signal output. It is suitable for continuous detection of CO concentration and on-site sound and light alarms in various industrial environments and special environments.

Working Principle

The instrument consists of a sensor, a processing unit and a display unit. It adopts the electrochemical principle and uses the sensor to convert the collected CO gas concentration signal into an electrical signal, which is transmitted to the processing unit in the form of a standard signal. The processing unit receives the signal from the sensor unit, processes it, and performs logical analysis to synchronously display the carbon monoxide gas concentration value. When the CO gas concentration value to be measured exceeds the warning alarm value, it responds in the form of an audible and visual alarm.

Product Features

• Standard MODBUS/RS-485 communication protocol digital signal output;
• Standard 4-20mA analog signal output;
• On-site sound and light alarm and alarm dry contact output, high and low alarm values​can be set in the full range;
• Quick response;
• Storage function. Over-concentration alarm value storage, over-temperature alarm value storage, operation record storage;
• Various reminder and alarm functions. Sensor expiration reminder function, over-concentration alarm function, over-temperature storage function, fault alarm function, etc.
