Add to enquiry


Flammable/combustible gases – 4-LEL-2.3V sensor. Ideal for portable, fixed flammable and hydrocarbons gas detection applications

Measuring Range: 0-100% LEL

Sensor Size: 4 series

Part no: 2112B6112400 (CLL-6112-400)

The 4LEL-2.3V offers fast response and sensitivity to a range of hydrocarbons for flammable gas detection levels. 


Pellistors allow you to reduce calibration requirements, increase customer confidence and repeat business. This is a metal housed sensor fitted with an integral flame arresting sinter, making it ideal for use in certified equipment. The sensor has ATEx, IECEx and UL approvals.

Note: Please refer to individual datasheet for detailed information on this item. 

Available options:

– For flammable fixed gas detection applications, see our CAT16 pellistors (part no. 2112B2016).

– For flammable portable gas detection applications, see our CAT25 pellistors (part no. 2112B2125).

– For a complete transmitter solution, see our optional 4-20mA output transmitter (part no. 2112B1000) with test/calibration cap (part no. 2112B1010). MODBUS cards (part no. 2112B1010) and gas detection controllers (2112BGWZ-S2/4/6) are available to link functions upstream, such as alarms and ventilation, with our 4-20mA output transmitters.

– For infrared sensors, see our 4 and 7 series sized infrared sensors (part no. 2112BM4/P4), also available with voltage transmitter output or bridge type dc (part no. 2112BM4/P4-V).
