Why the laser level sensor is the standard for narrow, structure-filled, and low-dust vessels.

Aim the beam exactly where you need it

The less-than-1° beam has virtually no divergence, so you can thread it past ladders, augers, and corrugated walls and put the measurement right on the outlet or the bottom of the hopper. An adjustable flange gives up to 10° of aiming, and the firmware corrects for angled mounting automatically.

Fast, accurate readings the material can’t fool

Eight readings per second, accurate to ± 1 inch — and unaffected by surface angle, slope, texture, granularity, or material color. Laser doesn’t depend on dielectric constant, so it reads bulk solids of any dielectric and even opaque liquids the same way.

More than inventory — catch plugged chutes and buildup

The same sensor handles continuous level control, plugged-chute detection, and buildup monitoring in chutes, crushers, and restrictive process equipment where other technologies can’t fit or can’t aim tightly enough.

Built to stay clean and easy to commission

An integrated still-air barrier keeps dust off the optics, with an optional air purge for tougher spots. Configure and align in the field over USB — no need to fill or empty the vessel, and no field power required just to set it up.

Models

Three BinMaster laser sensors, all measuring with the same narrow-beam technology. They differ in how they’re powered, how far they reach, and where the data goes — the wired LL-100 is the high-accuracy industrial workhorse, while the battery-powered SPL-200 and FVL-200 add wireless install for solids inventory and feed bins. Send us the application and we’ll spec it for you.

Configure your laser level sensor to your application

Lasers are deployed across a wide range of vessels, materials, and mounting locations. To ensure a reliable reading wherever it’s installed, each laser’s mounting, aiming, and accessories are configurable to your application. Not sure which configuration fits? Tell us about your application, and we'll spec the right mount for you.

BinMaster Laser Level Sensor Mount

LL-100

The LL-100 installs through a 2.5” process connection or a 4” flange on the silo roof, or on a stainless bracket inside the vessel above the material.

  • Adjustable flange — loosen the clamp ring, aim the sensor body up to 10°, and tighten in place; firmware corrects the reported distance for the mounting angle.
  • Swivel-style mounting accessories for precise aiming past internal structure.
  • Internal bracket mount for measuring below dust hoods or roof structures.

SPL-200 and FVL-200

Both battery sensors thread into a 1.5” NPT connection through a 2.5” hole in the silo top.

  • Adjustable swivel plate — 0° to 40° aiming.
  • Fixed-angle plate — 0°, 5°, 10°, or 30° to match flat or sloped roofs.

The laser sensor pairs with a handful of accessories that keep the optics clean and get the data where it needs to go.

  • Air purge kit — 1/8” BSP connection blows the lens clean for reliable readings in dustier or vapor-prone spots (LL-100).
  • Still-air barrier — Integrated on the LL-100 to keep dust particles from interfering with the optics.
  • LTX-100 gateway — Connects the wired LL-100 to BinCloud for remote inventory and networked communications.
  • LoRa gateway — Links the battery-powered SPL-200 and FVL-200 to BinView, Binventory, or FeedView over ethernet or cellular — up to one mile line-of-sight to the sensor.
  • Mounting plates & brackets — Adjustable and fixed-angle plates, swivel mounts, and internal brackets (see Mounting above).
  • Replacement battery — Field-replaceable three-to-five-year lithium battery for the SPL-200 / FVL-200 — swaps as easily as a flashlight.

Industries where the laser is the right solution

Serving industrial facilities across Ohio, Pennsylvania, West Virginia, and Western New York since 1959. Find your application below — or tell us about your vessel and we'll spec the right model.

Mining and Minerals

Aggregates, ores, salt, and minerals in crushers, load-out bins, and storage silos. A tight beam aims down crusher throats and narrow chutes where broad-beam sensors struggle.

Common fit:
LL-100 for crushers and plugged-chute detection; SPL-200 for wireless mineral inventory

Aggregate & Crushers

Sand, gravel, and crushed stone at aggregate yards and processing plants. Plugged-chute detection and buildup monitoring at transfer points.

Common fit:
LL-100 for chute and crusher level; ask about radar for dusty silos

Plastics and Resins

Virgin and regrind resin pellets, masterbatch, and ground polymer in day tanks and rail-car silos — low-dust pellet storage across Ohio and Pennsylvania.

Common fit:
LL-100 for tall narrow silos; SPL-200 + ResinView in BinCloud for wireless inventory

Grain and Feed

Grain, seed, fertilizer, and livestock feed in tall bins and farm silos. Battery/wireless install keeps feed and remote bins off the wiring budget.

Common fit:
FVL-200 + FeedView for feed bins; SPL-200 for grain and seed inventory

Bioenergy and Wood

Wood pellets, biomass, and densified fuel at pellet plants and biomass-fueled facilities. Narrow silos and low-dust pellet storage suit a focused beam.

FAQ

Use laser when the vessel is narrow, full of internal structure, or when you need to aim a tight beam at a specific point — an outlet, a chute, the bottom of a hopper — and the environment is relatively low in dust. Laser also reads opaque liquids and bulk solids of any dielectric, and it’s the tool for plugged-chute detection and buildup monitoring. Use 80 GHz non-contact radar when there’s heavy dust, steam, or condensation, or for large dusty silos where the signal has to punch through airborne particles. We sell both — send us the application and we’ll give you the honest answer, not the expensive one.

No — and that’s the one thing to know before choosing laser. Optical technology needs a relatively clear path, so BinMaster positions the laser line for low- to no-dust vessels. An integrated still-air barrier and optional air purge keep the lens clean, but for heavy dust, steam, or condensation, non-contact radar is the better choice. If you’re not sure how dusty your vessel really is, tell us the material and fill method and we’ll steer you right.

Yes. Because laser doesn’t depend on dielectric constant, the LL-100 measures bulk solids, pellets, and granular materials of any dielectric, plus opaque liquids. It’s unaffected by surface angle, slope, texture, granularity, or color.

The LL-100 is the wired, high-accuracy industrial sensor — up to 160 ft, ± 1 in, eight readings per second, a 4–20 mA output for direct control-system integration, plus plugged-chute and buildup monitoring. The SPL-200 and FVL-200 are battery-powered wireless sensors that skip wiring entirely: a three-to-five-year lithium battery and LoRa radio send hourly readings to the cloud. The SPL-200 reads solids up to 98 ft into BinView or Binventory; the FVL-200 is tuned for livestock feed bins up to 35 ft into FeedView.

Yes. The LL-100 is regularly used for plugged-chute detection and for monitoring buildup in hoppers, crushers, and restrictive process equipment. Its narrow beam can be aimed straight down a chute or at a specific surface, so it flags a blockage or accumulation before it becomes a problem.

Yes. The LL-100 provides a standard 4–20 mA NAMUR output that wires into virtually any PLC, DCS, or HMI, and it’s compatible with the LTX-100 gateway and BinCloud for remote inventory. The battery-powered SPL-200 and FVL-200 report wirelessly to BinCloud/BinView and FeedView rather than to a control system. If you have a specific integration question, we can confirm compatibility before you order.

Depends on the model. The LL-100 needs 24 VDC and a 4–20 mA home run back to your system. The battery-powered SPL-200 and FVL-200 need neither — the lithium battery powers the sensor, and LoRa radio carries the reading up to a mile line-of-sight to a gateway, which connects to the internet by ethernet or cellular. That makes the battery models a good fit for remote or hard-to-wire vessels. We’ll map the data path as part of speccing the system.
