 Illiana
has recently completed a successful installation of a lower
explosive limit monitoring system at a local facility.The
customer manufactures heat-activated printing ribbons. The process
involves applying a solvent-based ink to a file ribbon, running the
ribbon through a drying oven, and recoiling it.
The MSA system we installed features nine duct-mounted Ultima X
infrared LEL sensors and a Model 5600 monitoring system. By mounting
the sensors directly in the duct, we were able to shorten response
times (as compared to a sample draw system).
Our installation job included cutting holes in the ductwork to
mount the Ultima sensors. All sensor wiring was run back to the
Model 5600 panel in 1" rigid conduit. Pouring bodies and special
flex couplings were used in all classified areas.
The Ultima monitors and the 5600 control panel were centrally
mounted. We also fabricated a custom 10-valve gas manifold, and ran
Polypro tubing to the sensors, so that all sensor calibration could
be performed from the control panel.
 Work on this system was completed by Illiana's MSA factory-trained technicians.
