MSA A-ULTX-SENS-31-1-0 Gas Sensor

Feature & Principle

It is a catalytic bead combustible gas sensor for MSA Ultima XE gas transmitter. It detects flammable gas concentration based on catalytic combustion principle. When combustible gas contacts the heated catalyst bead, oxidation reaction occurs and temperature changes, the circuit converts temperature variation into electrical signal to calculate LEL value. It can continuously monitor explosive gas, output signal to the host for alarm and interlock.
