Why this principle
Dual-beam IR sees methane’s absorption band, resists catalytic poisons and works in inert atmospheres.
Typical applications
Fixed-point leak monitoring into a controller/ESD on 4–20 mA. Magnetic bump test without a hot-work permit.
Installation
Wall-mount SPXCDULNRX through the one-piece plate with M8 bolts. Entries 2 × ¾″ NPT — glands must match. Land 4–20 mA as three-wire. Magnetic wand calibration stays non-intrusive.
