A Laser Through Beam Sensor with the Edge

The Conventional infrared though beam sensors found in many manufacturing installations can generate unexpected malfunctions that could lead to many hours of investigation and maintenance to resolve.  Panasonic design engineers embraced this situation as a challenge, find a way to simplify this investigative process and make life easier for the operators and engineers involved in the tasks at hand, ultimately saving companies time, money and a lot of hassle!

Designed for use on manufacturing and processing lines, the HG-T Series Laser Through-beam Sensors feature a built-in self-monitoring function that diagnoses the current operational state and notifies the user when readjustment of established settings have drifted and when maintenance is required. The sensor determines its status and indicates Normal, Notification, Caution or Fault via its controller. When not in its normal status, the sensor identifies the cause of the problem and the corrective measures required, reducing equipment downtime and maintenance workload.

Finding the Edge

A HG-T Laser Through-beam Sensor installation, which consist of an emitter,  receiver unit and a controller, produces a flat, belt-shaped laser beam with a height of 10 mm which is ideal for tasks such as checking the contours of an edge, shaft diameters or the inside diameter of a product. The sensors have a sensing range of 500 mm, achieving a repeatability of < 1µm and have a linearity of less than ± 12µm over their measurement range, meaning that they are suitable for a wider range of applications than those infrared sensors with a shorter sensing distance.

Quick to install, the sensor heads are equipped with a beam alignment function to help speed up commissioning. Easy to set up by simply plugging the sensors into the controller unit which then automatically detects whether the emitter and receiver are connected correctly.

Available in two different sensor head versions, both with the same capabilities and only differing in their physical dimensions. The receiver of the slim version is 10 mm narrower than the standard model making it suitable for installations with very limited space where the standard version would perhaps be too large.

The HG-T Laser Through-beam Sensor Controller

The HG-T Through-beam sensor controller unit (purchased separately or as part of a kit) is equipped with a current voltage output that can be selected according to the application requirements. A 2 line digital display simultaneously shows the sensor head measured value the calculated value with an intuitive circle meter helping to display the values in a simple way. Six types of detection mode to select from make commissioning with this controller easy. External inputs allow the user to control laser emission, reset the device or save data during the process, supports high-speed sampling with a frequency of up to 2kHz.

  • Six types of detection mode
  • Auto edge detection mode
  • Edge detection mode
  • Inside diameter / gap detection mode
  • User assigned edge detection mode
  • External form / width detection mode
  • Central position detection mode

 

Outstanding sensor performance

Thanks to functions like filters, edge detection, light intensity checks and averaging of measurement values (up to 1024), means that the measured parameters can be relied upon. These functions help you to detect, at an early stage, when the measuring process isn’t running correctly and attention is needed.

Multiple sensors

The master-slave system allows you to connect up to 15 laser through beam sensors in series. Another handy and time saving feature, increasing ease-of-use, is the ability to copy settings from the master to the slave units, with an LED indicating when copying is in progress.

HG-T Laser Through-beam Sensor Applications

  • Guiding the sheet edge of battery electrodes
  • Checking diameter and position of threads or wires
  • Detection of individually stacked wafers
  • Guiding of translucent films
  • Measuring of drill holes in motor components
  • Measuring the material thickness of films or textile webs
  • Highly precise measuring and checking of web edges
  • Glass substrate positioning
  • Diameter measuring

Note: The optional side view mirror makes it possible to deflect the beam by 90°.

Safety Light Curtains with Advanced Bluetooth Interface

Safety light curtains, or as they are often known as – light barriers, light grids and light guards to mention just a few alternatives are classed as Electro-sensitive Protective Equipment. Consisting of a transmitter and a receiver head, light curtains generate a field of infrared light between these heads which is classed as the detection zone.

Invisible Light Protection

Typically, these diligent devices are situated around access points to a piece of processing machinery, shutting down the device should a person, or a part of a person, cross the beams of the safety grid.  Advantages of a light curtain include reduced operator fatigue, when compared to mechanical options such as gates and barriers, and the subsequent upkeep of these mechanisms and simplifying maintenance and set-up times.

safety light curtain installation

Utilised across numerous industry sectors for many years, light curtains come in many shapes and sizes. Schmersal, renowned for their impressive range of Safety Light Curtains decided to add yet more functionality to these popular process safety devices by adding a built-in high specification Blue Tooth interface.

The Schmersal SLC440/COM Safety Light Curtain range with built-in Bluetooth BLE (BLE stands for Bluetooth Low Energy) is an active optoelectronic protective device that can provide real-time status and diagnostic data of the light grid on a smartphone or a tablet via a Bluetooth interface.

Ideal for Predictive Maintenance

The Bluetooth interface allows easy start-up using a smartphone or tablet with the integrated set-up aid. There is also the useful option of saving the data, which can then be used to document a repeat test or for predictive maintenance purposes. The transmission of data to smartphones / tablets (Android, IOS) is facilitated by an app developed by Schmersal.

NFC technology has been used successfully in the past when it came to recording and monitoring device diagnostic data, however it is limited to only a few centimetres. The Bluetooth BLE interface contained within the SLC440/COM Light Curtains can achieve a range of up to 100 times more, around 5 metres in total.

This means the BLE interface is perfect when the safety light curtain installation is in a relatively inaccessible position. Bluetooth BLE also offers a greater range of applications because not all smartphones or tablets are equipped with NFC. As Bluetooth is an international industrial standard, the SLC440/COM range can be used all over the world.

safety light curtain installation

Safety and Efficiency

The SLC440/COM Safety Light Grid with BLE are ideal for improving efficiency and availability in manufacturing processes as their status can be accessed easily and in real-time, meaning issues can be captured early. Status information and diagnostic data enables processes to be reactivated quicker, particularly in the event of a system shutdown if a hazard is detected.

It also represents an economical innovation as, compared to classic Bluetooth, BLE is characterised by considerably lower energy consumption and reduced costs at a similarly high communication range.

All of the SLC440/COM range of light curtains are available from Kempston Controls, give our sales team a call on +44 (0) 1933 411 411 or email them at sales@kempstoncontrols.com, or use the enquiry form below and let us help you select your ideal light curtain solution.

PP20H Pressure Sensor IOlink

IO-Link for Centralised Configuration

When an IO-Link option is utilised, this makes it possible to configure several pressure sensors simultaneously, simplifying switching point adjustment for different process stages and ultimately saving time and money. Data is the fundamental building block of process and product optimisation and using IO-Link ensures that valuable, additional data is accessible for analysis. Apart from the analogue 4 … 20 mA signal, further data such as cell pressure and pressure sensor temperature can be recorded. This process data can be used, for example, to determine the temperature of the medium being used. Further data that can help to identify the sensor can be loaded at any time using tags that can be configured individually.
