3.7 Line Integrity Test

Honeywell offers the optional capability to check for leaks in Midas S2 sample lines. Midas S2
Transmitter for Line Integrity Test detects any leak in the tubing with a pneumatic signal
change from the valves installed at the end of the sample line. This test is performed
automatically as a Line Integrity Test. The Line Integrity Test Option requires the Calibration
process.
If you make any changes to the Pump Module, Check Valve, Filter, and Tube, start a
l
new Line Integrity Test calibration again.
Verify the Check Valve flow direction during installation.
l
Verify both the Check Valve and Tube are firmly assembled.
l
Mark the insertion from the end of the tube to the length of 15.5mm. When inserting
l
the tube, make sure the insertion is up to the marked position.
The external filter is installed further from the Transmitter and the Check Valve is
l
installed closer to the transmitter.
Si vous apportez des modifications au module de pompe, au clapet antiretour au
l
filtre et au tube, refaites un nouvel étalonnage du test d'intégrité de la ligne.
Vérifiez le sens de circulation du clapet anti-retour pendant l'installation.
l
Vérifiez que le clapet antiretour et le tube sont solidement assemblés.
l
Marquez l'insertion sur l'extrémité du tube à la longueur de 15,5 mm. Lors de
l
l'insertion du tube, assurez-vous que l'insertion atteint la position marquée.
Le filtre externe est installé plus éloigné de l'émetteur et le clapet antiretour est
l
installé plus près de l'émetteur.
