SEARCHLINE EXCEL PLUS Gassing Test Cell
The gassing test cell allows the Searchline Excel™ Plus and Searchline Excel™
Edge calibration to be checked using a user-specified gas concentration, as an
alternative to the standard functional test filters.
CAUTION
Prerequisite for calibration check using the gassing test cell is installation
of the Honeywell Fixed Platform App to a suitable handheld device.
The test gas must be the same as the gas calibration of the Searchline Excel
Plus or Searchline Excel Edge units and ideally the concentration should be
between 2 and 5 LEL.m, never below 1 LEL.m.
Note
For Universal Calibration units any of Methane, Ethane, Propane, Butane,
Ethylene can be used. Natural gas mixes can also be tested.
Note
Cross-calibration is not recommended. Typical values for crosssensitivity are
not sufficiently precise to enable valid calibration checks using the gassing
test cell.
Response tests can easily be performed with the functional test filters.
Refer to the Technical Manual for more information.
WARNING
Take necessary precautions to ensure safety when dealing with high
concentration gasses.
The gassing test cell supplied by Honeywell Analytics (Part No: 2017B0185)
is 170 mm (6.7 in) long, weighs 958 g (2.11 lb), with gas path 138.8 mm
(5.46 in).
The following table outlines the response expected when using this gassing
test cell:
Gas type| LEL of the gas (% v/v)| Concentration applied (%
v/v)| Calcul ated response with 138.8 mm (5.46 in) gas path (LEL.m)|
4-20 mA output (mA)
---|---|---|---|---
Methane| 4.4| 80| 2.5| 12.0
Ethane| 2.4| 43| 2.5| 12.0
Propane| 2.7| 31| 2.5| 12.0
Butane| 1.4| 25| 2.5| 12.0
Pentane*| 1.1| 20| 2.5| 12.0
Ethylene| 2.3| 42| 2.5| 12.0
Propylene| 2.0| 36| 2.5| 12.0
- Pentane cannot be used with the gas sing test cell . At normal temperatures, this s ubs tance does not vaporise s ufficiently to give a usef ul signal in the short path of the gas sing test cell .
WARNING
These gases are flammable and some are toxic. Take appropriate precautions when handling.
CONNECT THE GASSING TEST CELL
- Connect the gassing test cell to the receiver. Ensure the locking tab clicks into the right position.
- Rotate the handle clockwise to lock the gassing test cell onto the receiver.
- Zero the receiver with the empty gassing test cell.
- Apply the test gas to the gassing test cell. Avoid pressurising the test cell. Wait for the receiver output to stabilise.
- Check if the receiver output is as indicated in the table above, ±5% FSD.
- Remove the test gas from the gassing test cell.
- Remove the gassing test cell.
- Re-zero the receiver.
Note
Field calibration is not supported. If result is not as expected contact an
authorized service centre.
