Measuring and switching with one device
Is there an object on the conveyor belt? If yes, what is its position or distance to the machine? These are typical issues that need to be addressed in a wide range of industrial applications and processes. With the new ODT 3C from Leuze, only a single device is needed: The innovative sensor can transmit both switching and measuring information to the machine control system, making it an efficient and economical 2-in-1 solution.
The ODT 3C transmits measurement values and extensive diagnostic data via IO-Link. The data includes temperature values, warnings, and signal quality. It features impressive black-and-white behaviour (< ±3mm at 150mm). The operating range can be easily adjusted via the teach button, remote signal or IO-Link. The new Leuze sensor also offers impressive functional reliability. Active ambient light suppression prevents faulty switching, even when exposed to direct light from LED building lighting systems. LEDs that are easily visible from all sides allow users to quickly read the status of the ODT 3C. Two independent switching outputs and sensor models with warning output or a small light spot (pinpoint) round off the sensor’s functions. This enables plant operators to use the ODT 3C flexibly in a wide range of applications.
As an application example from the food industry, if a machine is rolling off dough for baked goods, the ODT 3C sensor would be pointed down onto the dough. It would send a distance value to the parent control. The goal would be to regulate the dough within an optimal distance range of 100–120mm. If the sensor detected a measurement value outside the target range, the conveyor belt motors could adjust the speed of the conveyor accordingly. The measurement value is evaluated in the process data via IO-Link. In addition, diagnostic data is transmitted to the controller via IO-Link for Industry 4.0 purposes.
