Measuring the thickness of urethane foam sheet

Measuring thickness in order to maintain uniform urethane foam sheet thickness

You wish to measure thickness in a precise manner so that you can maintain uniform urethane foam thickness (within ±100 μm).

[Issue] Unevenness caused by surface bubbles

Since the surface of the urethane foam sheet is made uneven by bubbles, it’s difficult to make stable measurements using a reflective displacement sensor.

[Solution] Measure sheet thickness using a Thru-beam Type Digital Displacement Sensor and implement feedback control.

Measure sheet thickness using a HG-T Series Thru-beam Type Digital Displacement Sensor and implement feedback control.

High-precision measurement　

Detect location with a high degree of precision at a resolution of 5 μm (at an installation distance of 500 mm).

Easy installation

Includes a beam axis adjustment assist function! Installation is simple since the direction in which the emitter and receiver are misaligned is indicated by the beam axis adjustment indicator.

Rugged design

Features a die-cast aluminum enclosure! With little variation in measurement precision with temperature and little distortion due to screw-tightening, the sensor resists changes in characteristics over time!

Space-saving design

Compact head measures just 8 mm × 30 mm × 60 mm!

A slim model measuring 8 mm × 20 mm × 60 mm in is also available.
