SI-200A

Ex ia Fixed Gas Detector

DESCRIPTION

SI-200A is an intrinsically safe (Ex ia) fixed gas detector designed for fast and accurate detection of toxic gases such as HCl, NH?, and Cl?—gases that often suffer from delayed response due to adsorption in conventional flameproof (Ex d) detectors. With its optimized sensor housing and internal structure, the SI-200A minimizes adsorption effects, ensuring faster response time and higher measurement accuracy.

This diffusion-type explosion-proof detector is suitable for hazardous areas where toxic, oxygen, or combustible gases may be present. It features a large LCD for real-time gas concentration display and self-diagnostics. The device supports 4–20mA analog output (HART optional), RS-485 digital communication, and enables convenient configuration and calibration via wireless connection.
