The Laser Advantage

The ultimate solution for industrial process challenges, Optech’s laser rangefinders exploit the unique properties of light to produce precise, reliable, fast measurements. High update rates provide accurate measurements even when objects move quickly or material levels change rapidly. "Last-pulse logic" and internal windowing software filter out any false returns from obstacles passing between the rangefinder and the object or material.

Optech Technology

• Rapid measurements, up to 15 readings per second
• Accurate, with absolute accuracies of 2-4 cm depending on the model
• Non-contact, non-intrusive measurements
• Measure through moderate amounts of dust, by using advanced software
• Narrow beam divergence for long-range tracking of small targets, accurate unit location/alignment, and to aim past obstacles
  

Laser Measurements Are Unaffected By…

• Moderate amount of dust
• Mounting angle or orientation
• High temperature or temperature variations
• Background noise
• Vehicle vibration
• Vapor pressure
• Off-gas layers or steam
• Vacuum barriers
• Low dielectric constant of material

Sentry SR

The Sentry SR series is the latest in laser technology, designed for both level monitoring and object positioning. It operates at short ranges of up to 25 meters, and is housed in a rugged, explosion-proof enclosure.

Sentry SR Level Monitors are:

• Optimized for short-range applications (less than 25 m)
• Available with a cooling plate option, extending operation to 150°C.

All Sentry SR Series Level Monitors are available in DV and CP models:

• DV: Optimized for performance in environments with excessive dust and vapor
• CP: Optimized for clear path applications.

Sentinel Series

The Sentinel series of non-intrusive, non-contact level monitors meets inventory control challenges reliably and accurately. The Sentinel monitors material levels in simple or complex vessel applications, providing high performance at ranges of up to 150 meters.

The Sentinel series includes the following units:

• 3100: Standard level monitor, optimized for long-range applications (greater than 25 m)
• 3310/3315: Extends operating temperature to 100°C/150°C.

All Sentinel 3000 Series Level Monitors are available in DV and CP models:

• DV: Optimized for performance in environments with excessive dust and vapor
• CP: Optimized for clear path applications.
