Ask Dr. Level

The Electro-mechanical "Meter Drive" instruments are extremely  accurate long range, up to 820 feet (250 m), displacement (level/position) measuring devices, ideal for applications in harsh industrial environments requiring high precision.

Model Z-200 includes optical linear incremental coders using a metallic perforated rule as a reference.  The maximum resolution is 0.04" (1 mm).  Its primary use is for displacement measurements in automatic conveying. Measuring lengths can be up to 820 feet (250 m). 

System components : 

Rule		Stainless steel perforated rule.  Manufacturing accuracy is 0.1 mm/m Lengths up to 820 feet.
Opto-electronic Differential Detector Head		Resolution 0.04" (1mm) Available pre-wired (shown) or unwired for flexibility

Model Z-300 includes optical linear incremental coders using an extremely accurate metallic perforated rule as a reference.  The maximum resolution this unit is an amazing 0.004" (0.1 mm).  Its primary use is for displacement measurements where the model Z-200 does not provide adequate resolution. Measuring lengths can also be up to 820 feet ( 250 m). 

System components : 

High-Accuracy Measuring Rule		High accuracy stainless steel perforated rule Supplied with individual calibration test sheet  Lengths up to 820 feet.
High Resolution Detector Head		Resolution 0.004" (1mm) Available pre-wired with various cable and/or connector configurations Reading speed up to 10 m/s.
