Displacement Sensors: Technology & Design

The SLS320 displacement sensors range is designed to provide maximum performance benefits within a body diameter of 32mm, with stroke lengths from 250 to 1600mm. With a choice of mounting options and accessories, this sensor is ideally suited to a wide range of heavier duty industrial applications, for medium to long stroke linear position sensing

Using the proven benefits of Hybrid Track Technology and including a number of unique design features, the SLS320 is ideally suited to high volume OEM manufacturers, where high performance and reliability with competitive pricing and rapid despatch has paramount importance.

Options

  • Compact shaft: Compact shaft will reduce dimension D by 50mm
  • Integral shaft seal - IP 66: Designed to accept integral shaft seal to give IP66 rating
  • Cabled socket: 1m or 10m cabled socket assemblies available
  • Mounting: Body clamp or flange mounting kits can be supplied
  • Protective sleeve: For all stroke lengths - self aligning bearings only. See ordering code

Displacement Sensors: Purpose & Functionality 

Displacement sensors are non-contact devices that are used to measure the position of an object and the range of its reference position. They are also capable of measuring the thickness, height, width, and density of non-conductive materials. The measurement taken can then be converted into movements, such as pressure and acceleration. There are numerous types of noncontact displacement sensors, including optical/laser, capacitive, and inductive sensors.

Benefits

Displacement sensors come with a range of benefits that are highly sought after in many applications. 

  • Robust - Highly resistant to shock, vibration, overload, and misalignment.
  • Outstanding repeatability - Highly predictable.
  • Versatile - Can be adapted to different size needs, range or electrical output.
  • Precisely accurate - capacitive sensing.
  • Improves linearity across measurement range.

Displacement Sensor Applications

Displacement sensors are specifically designed to add value in industrial applications where precision and robustness are equally important. Here are some industrial applications that rely on the operation of displacement sensors:

  • Production process optimization
  • Structural health monitoring
  • Control of heavy-duty off-road vehicles
  • Factory automation

Displacement sensors are used for measurement and so are vital in the event of:

  • Gaps
  • Vibrations
  • Expansion
  • Material strength
  • Incline
  • Position shifting
  • Temperature expansion

FAQS:

How does a displacement sensor work?

A displacement sensor measures the distance between an object and the sensor. They operate this way dependent on the element used in the sensor. There are numerous options available, such as light, magnetic fields, or sound waves. 

If using a laser displacement sensor, the triangulation method is applied by combining the emitting element and the positioning device to perform the measurement. The laser is focused through the lens and projects onto the object. Then the beam of light is reflected from the object back to the position sensor device. When the object moves the sensor device moves too, detecting the changes in position detects the amount of object displacement. 

How many types of displacement sensors are there?

There are several types of displacement sensors available for applications that perform best in specific applications:

  • Potentiometer
  • Strain gauge
  • Capacitive sensors
  • Linear variable differential transformer
