IO-Link pressure and temperature sensors ensure uniform feed and flow of adhesives

When installing vehicle windshields, an adhesive robot with a dispensing head applies adhesive along the outer edge of a windshield. For optimum results, the correct consistency and quantity of the adhesive must be dispensed at all times.

Your Benefits

  • High system availability due to rugged sensor design
  • More cost-efficient than alternative applications that have viscous flow meters 
  • Additional condition monitoring data can be captured with IO-Link

  • PS+ and TS+ sensors monitor the temperature and flow of the adhesive

  • Adhesive is applied around the windshield by an adhesive robot with a metering nozzle

  • The display changes color when defined switching points are exceeded

TS+ temperature sensors ensure the optimum flow 

The perfect viscosity of the adhesive can be determined by its temperature. If the adhesive is too cold, it becomes viscous. If it is too warm, the adhesive will be too thin. To prevent too much or too little adhesive from being applied, adhesive drums are filled with adhesive and kept at the optimum temperature with the help of TS+ sensors so that they’re ready to use and dispense the perfect viscosity for each windshield application. TS+ sensors monitor the temperature and transmit the measured values to the controller via IO-Link.

PS+ pressure sensors ensure the feed of the dosing nozzle

In addition to temperature, the pressure applied to the system is crucial for monitoring the application. Unusual pressure changes can indicate a change in the viscosity of the adhesive, clogged metering nozzles or kinked supply lines. PS+ pressure sensors reliably monitor the pressure of the dosing nozzle  to prevent adhesive from settling or clogging the pressure channel.
