Please refer to Ch.15 Compatible Sensors for a list of
available detectors.
You can also use the TPPL Sensor Catalog to select
listed gases, or you can enter 'User gas' details if your
gas is not listed.
Please refer to Ch. 8.6 How to Update the Sensor
Catalogue for further information.
Note: The Target Gas Type is automatically entered by your choice of Sensor Type.
Note: The Sensor Type gases will vary with different types of Detectors. Gases listed with a '-2' suffix are compliant with
EN 60079-20-1 LEL levels.
Note: Sensors must be recalibrated when selecting a new target gas.
Note: mV-bridge sensors are not suitable for use in oxygen enriched atmospheres (e.g. >21 %v/v) as the bridge bead will
be too reactive, leading to false readings and premature burn-out. However Oxygen deficient atmospheres (e.g. <10 %v/v)
may suppress sensor output because there will be insufficient bead reaction to change the bridge's resistance reading.
