Product Description
Explosion Proof Fixed Gas Detector for Hazardous Areas
K800 Ex d IIC T6 Fixed Gas Detector for Hazardous Areas with 4-20mA and RS485 Output

K800 is an industrial fixed gas monitoring detector developed for applications where combustible or toxic gas leakage needs to be continuously monitored.

With an Ex d IIC T6 explosion-proof enclosure and IP66 protection, the detector is designed for demanding industrial environments. Depending on the gas being monitored, K800 can be equipped with catalytic, electrochemical or infrared sensor technology.

The system supports 4-20mA, RS485 MODBUS and relay outputs, allowing the detector to communicate with gas detection controllers, PLC or DCS systems.


Gas Detection Options

The K800 platform supports a wide range of gases, including:

  • O2
  • CH4 / LEL
  • CO
  • H2S
  • SO2
  • NH3
  • Cl2
  • NO2
  • NO
  • O3
  • PH3
  • H2
  • HF
  • HCl
  • HCN
  • VOC
  • CO2
  • C3H8

For example, the standard datasheet lists CH4 at 0-100%LEL, CO at 0-1000/2000 ppm, H2S at 0-200 ppm and O2 at 0-25/30%vol, with the exact range depending on the selected sensor configuration.


Key Features
1) Digital and analog outputs

2) LED status indicator light for alarm conditions

3) The relay can trigger alarms or process control system

4) Three models available for measuring toxic gases, VOCs, or combustible gases

5) Explosion-proof case

6) CERTIFICATIONS: CE, CMC, Ex, MA (SAFETY CERTIFICATE OF APPROVAL FOR COAL MINING PRODUCTS IN CHINA).


Industrial Integration

K800 can provide gas concentration signals to a central control system. Its relay outputs can also be used for alarm linkage and external equipment such as ventilation fans.

This makes it suitable for continuous gas monitoring projects where local detection and centralized control are both required.

Product Description Version 3 — PLC / DCS Integration

Fixed Gas Detector with 4-20mA and RS485 MODBUS

K800 is designed for integration into industrial gas detection and automation systems.

The detector provides 4-20mA analog output, RS485 MODBUS communication and 3 relay outputs, allowing gas concentration data and alarm signals to be transferred to PLC, DCS, gas controllers or other control equipment.

Typical System Connection

K800 can transmit 4-20mA or RS485 signals to a K1000 controller, PLC system or other central control unit.

For projects requiring automatic alarm linkage, the relay outputs can be configured to trigger external devices after the gas concentration reaches the preset alarm threshold.
