General Description:

The Nemoto NCP-180S-7S is a catalytic (pellistor) type flammable gas sensor supplied as a matched pair of elements mounted on a single header and protected by a metal can.  The sensor detects and measures the presence of flammable gases and vapours in air, in the range 0-100% of the Lower Explosive Limit (LEL) of the gas or vapour being measured. The sensor is primarily designed for use within Fixed Gas Detection Systems.

The NCP-180S-7S is designed to bring together the performance levels normally expected from twin header devices with the cost benefits of single header design. As such we believe the NCP-180S-7S sensor to represent both the best performing and most cost effective fixed system catalytic gas sensor of its type on the market today, for the most challenging Industrial applications and environments.

  •        Measures flammability directly

  •        Superb Zero Stability

  •        Highly resistant to Catalyst poisons

  •        Resistant to shocks and vibration

  •        Effectively Linear output to 100%LEL

  •        Specific to Flammable Gases

  •        Unaffected by Humidity

  •        Very Low Long term drift

 

 

NOTE: This particular sensor needs special circuitry handling to fully benefit from it's superb performance abilities, which is fully explained in the Manual for the sensor.
