NMP Gas Leak Alarm KGD-GAS-203
Product Introduction
The NMP Gas Leak Alarm KGD-GAS-203 is a high-performance NMP gas leak alarm independently developed by KACISE based on the non-dispersive infrared (NDIR) principle. It is suitable for detecting the gas concentration at the center of drying equipment and exhaust pipes. The sampling instrument body and the display part adopt an integrated explosion-proof structure design, which is convenient for installation and disassembly. At the same time, this instrument has the characteristics of automatic calibration, long-term maintenance-free operation, and a long service life. It has the functions of industrial 4-20mA current output, RS485 external communication, and alarm output when the concentration exceeds the limit, and can be applied to complex and harsh high-temperature industrial environments.
Product Features
- Detects high-boiling-point NMP solvent
- Can operate in a high-temperature environment of 0-160°C
- Direct insertion into the furnace to accurately detect the concentration at the center of the equipment
- Adopts a pressure-resistant explosion-proof structure, meeting the explosion-proof grade of Ex db IIC T3 Gb
- Integrated design, easy to install
