Product Introduction
The alarm features a wireless transmission module,4-20mA signal output and
RS485 interface, with the standard Modbus protocol provided by our company. At the same time, we support customized personalized products and fine-tuning of the alarm's output signal
and other functions, making it convenient for users to network and maintain their systems. In addition, customers can optionally equip an intelligent data acquisition and monitoring platform to achieve intelligent monitoring management,
monitoring data export, real-time data charts, and alarm record queries. This product has been widely used in environmental testing in municipal, school, hospital, and factory settings,
safety detection of hazardous gases, and in gas, petrochemical, metallurgical, environmental protection, fire safety detection, and other fields.
The alarm adopts imported electrochemical
sensor, with good sensitivity and excellent repeatability. When the sulfur dioxide (SO₂) in the airGasconcentration exceeds the preset alarm point, the gas monitoring system will immediately it immediately activates the audible and visual alarm signal or drives the exhaust system. The alarm is compatible with various control alarms,PLC, DCS and other control systems, and can also be used as a standalone unit
use. Customers can customize different types of products as needed, such as with or without on-site display, and with or without on-site audible and visual alarms.
