For high speed printing processes, the limiting factor for the productivity of the equipment is usually ink drying time. To maximise printing speed without quality loss, it is important to be able to determine quickly when the printed substrate is sufficiently dry or fused.
The surface temperature of a wet substrate will rise very slowly as constant heat is applied to the product. This occurs because the moisture in the substrate absorbs much of the heat energy as it evaporates. At the point where the substrate becomes dry, however, the same constant heat supply will quickly raise the temperature until it reaches the same as the surrounding air.
The optimal solution
Infrared temperature sensors allow for fast measurement and no contact with the product. With the response time of the lRt/cs averaging around 100 milliseconds, it is possible to detect the dry out point quickly and increase production speed and yield.
You can also find the dry out point by installing an array of lRt/cs, and with the side view mounted sensors you can reach hard to access areas in any process.
Here are some reasons for choosing Exergen IR non-contact sensors:
• lRt/cs are self powered and intrinsically safe.
• Repeatability error of 0,01°C.
• Interchangeability error of ±1%.
• Resolution of 0,0001°C.
• Side view sensors if the available space is limited.
• All sensors are CE and RoHS rated.
Among the commercial advantages are an increase in yield, quality of the end product, profit, and production by increasing the printing speed.
