Nitrous Oxide Infrared Gas Sensors 

These Nitrous Oxide (N2O) infrared gas sensors measure Nitrous Oxide gas over the range 0-1% Volume. 
 
They are part of the Standard 'Gold' Series of sensors and are available in Industrial Ex d IIC Certified, Mining M1 Certified and Non-Certified versions. They are also UL approved. 
 
These sensors provide a 'raw' signal output which needs to be be fed into external processing electronics and software. This may either be provided by the equipment manufacturer or by use of a purpose-designed OEM-1Circuit Board (see below) available from Dynament Ltd. 
 
A sensor Development Kit is also available - see below. 
 
The sensor order codes commence with the code MSH-N2O/TC for 'Ex' Certified types or MSH-N2O/NC/TC for 'Non-Ex' types followed by code letters for the options below:- 
 
F - Self-adhesive 14 Micron PTFE filter for water ingress protection. 
I - An electrically isolated case. 
 
The tables below gives the order codes and description of typical sensor types.
