The LM80 is a non-contact laser level transmitter for continuous measurement of granular solids and opaque liquids in silos, tanks, and hoppers. It features a powder-coated aluminum or 316 stainless steel enclosure with IP66/NEMA 4X rating, and is rated for use in potentially explosive atmospheres under CSA, ATEX, IECEx, and FM standards. The device measures with ±10 mm accuracy up to 100 m for level applications and up to 150 m for positioning applications with reflective targets, offering 3 updates per second and a beam divergence of less than 0.3°. It includes a built-in red laser pointer for alignment, auto-ranging functionality, 4-20 mA and dual relay outputs, and operates on 18-32 V DC. The optical system has a 90 mm aperture with acrylic lenses, and the unit supports purge air flow via a 1/8 NPT fitting. Mounting options include ANSI 150 and DIN PN10 flanges, Triclover fittings, and universal plates.
Based on pulsed laser technology, the LM80 embodies speed and accuracy in a single, easy to use and install product. Whether measuring a few meters into the confined space of a crusher, or to the bottom of the tallest silo, the LM80 with its laser pointer and long range is the plug-and-play solution to level measurement.
The LM80 features advanced timing and sophisticated signal processing for pinpoint accuracy at up to 100 m (330 ft.) for level applications and up to 150 m (500 ft.) for positioning applications.
