Low-cost, robust displacement and positioning sensors
Description
Bestech Australia offers a wide range of
low-cost displacement and positioning sensor for displacement measurement in
harsh and dirty environment such as in manufacturing environment and mining
industry. Selecting the suitable sensors highly depends on the applications.
LVDT/LVIT is a low-cost, wear-free displacement
transducer with long service life. They have been successfully used in both
single and high-volume OEM applications and offer high reliability, excellent
signal quality and measurement stability in harsh conditions. Applications
example:
- Piston positioning
in hydraulic cylinders - Measuring lifting
height in platform - Gap measurement in
rotary crushers - Axis calibration
in robotic arms
Displacement is measured using a highly
flexible steel cable attached to the cable drum which provides a proportional
output signal. These sensors are applications-friendly, easy to mount and can
be customised for optimization in OEM applications. Some examples:
- Fork-lift lifting height
measurement - Measuring height of
lifting platform in automobile production - Positioning of
Aerial work platform (AWP)
Potentiometers are low cost and always operate with
a sliding contact system. They are used for direct measurement of mechanical
displacements. The mechanical moving parts of the sensors should be set up to
minimize movement intervention by external forces. Applications include:
- Press-fit
- Switch and button
deflections - Measuring strokes
on riveting machines - Hydraulic
cylinders
Low-cost,
contact capacitive sensors are available as elastometric strain gauge
technology. The sensor has robust, flexible design and capable of tolerating
off-axis measurement in all three dimensions. Applications example include:
- Measuring movement of cranes
- Gap and crack measurement in
structural health monitoring - Automated error detection in stamping/ metal forming tools
