YD-812N Fixed Isobutane Gas Detector with Display
Product Overview
Our company's intelligent gas detector uses natural diffusion to detect gas concentration, and adopts imported catalytic combustion sensors and infrared sensors with excellent sensitivity and repeatability; LCD or LED digital displays suitable for factory applications display the concentration value of leaked gas in real time, and immediately activate a light alarm signal when it exceeds the preset alarm point; The international standard (4-20) mA signal can be directly connected to the factory DCS system; The instrument adopts embedded microcontroller technology, with simple operation, complete functions, high reliability, and overall performance leading in China.
Main functions
The instrument adopts advanced 16 bit ultra-low power embedded microcontroller
LCD display (two-wire detector) or LED digital display (three wire detector)
Users can set their own high and low alarm points
Automatic calibration function to reduce measurement errors
Important operations require password verification to effectively prevent accidental operations
The standard (4~20) mA signal can be directly connected to the factory DCS system
