C-3
ACCURACY (per EN 60079-29-4)
4-20 mA Model: ±0.25 LFL-meters or ±12.4% of applied gas concentration, whichever is greater, with water
vapor @ ≥82°C.
LON Model: ±0.25 LFL-meters or ±15.2% of applied gas concentration, whichever is greater, @ –55°C.
RESPONSE TIME
4-20 mA Model
T50: 1.2 seconds (2.5 LFL-meters applied)
T90: 2.5 seconds (2.5 LFL-meters applied).
EQP Model
T90: 5.3 seconds* (2.5 LFL-meters applied).
* For EQP model only, average of three consecutive trials, with the minimum and maximum response times no
greater than ±2 seconds from the average indicated response time.
ALIGNMENT
Misalignment will cause the manufacturer stated accuracy limits to increase, but remain within the limits of
EN 50241-1, -2 and EN 60079-29-4.
