KACISE Gas Leak Alarm KGD - GAS - 312 For High - Temperature Industrial Environments

KACISE Gas Leak Alarm KGD-GAS-312 for High - temperature Industrial Environments

Product Introduction

The KACISE Gas Leak Alarm KGD - GAS - 312 is a high - performance 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, facilitating installation and disassembly. Meanwhile, this instrument features automatic calibration, long - term maintenance - free operation, and a long service life. It has functions such as industrial 4 - 20mA current output, RS485 external communication, and alarm output when the gas concentration exceeds the limit, making it applicable to complex and harsh high - temperature industrial environments.

Product Features

  • Long service life, maintenance - free, automatic calibration
  • Measured gas temperature: 0 - 160℃
  • Anti - interference, good long - term stability
  • Integrated design, direct insertion into the furnace
  • Adopts pressure - resistant explosion - proof structure, meeting the Ex db IIC T3 Gb explosion - proof grade
