The LM200 is a non-contact laser level transmitter for continuous measurement of granular solids and opaque liquids in silos and tanks. It has a powder-coated aluminum enclosure, 127 mm base plate diameter, and 303 mm length. It measures up to 190 m for level applications and 400 m for positioning with reflective targets, with ±30 mm accuracy and a beam divergence of less than 0.2°. Output options include a 4-20 mA NAMUR-compliant signal and two SPST relays. Powered by 24 V DC (18-32 V DC), it operates from -40°C to +60°C and carries IP66/NEMA 4X enclosure ratings. It is certified for hazardous locations under CSA Class I Division 2, ATEX II 3G Ex nA nC IIC T4 Gc, IECEx, and FM standards. The unit includes a 635 nm visible aiming laser and a 905 nm measuring laser with 25-year typical MTBF.
The measuring laser uses invisible, infrared light. There is a second, visible aiming laser to help with the alignment of the measuring laser. The laser beams have very little divergence so that accurate targeting is easy even in silos or vessels that have internal structures.
