Smart ultrasonic reflex sensor

June 2017 Sensors & Transducers

No larger than the Enter key on a PC keyboard, the U1KT001 ultrasonic reflex sensor from Wenglor is distinguished by a large range of 400 mm. Two independent switching outputs can be taught in via teach-in or IO-Link in order to detect liquids, as well as dark, transparent or reflective objects at any two switching points. These make it possible to monitor minimum and maximum values when measuring fill levels, distances and stack heights, even where interference factors prevail such as ambient light, fog or dust.

Sensor parameters can be conveniently configured and diagnostic data read out via the IO-Link interface. With the data storage function, saved settings can be easily duplicated at other sensors.

The two switching outputs are set up in just a few seconds with the help of the intuitive teach instructions on the back of the sensor. A lock function for the teach-in keys prevents inadvertent changes to the settings.

The device is also equipped with integrated temperature compensation which offsets fluctuating ambient temperatures in order to ensure constant, high precis-ion measured values. LEDs, visible all the way around, indicated the status power supply as well as the two digital switching outputs. The second sensor output can be used alternatively as a diagnostic output.

The ultrasonic sensor is equipped with three different operating modes: up to 40 sensors can be operated at the same time in the synchronous mode which is essential for scanning large surfaces. Up to 16 sensors can alternately emit pulses in the multiplex mode, because they do not influence each other. This is especially advantageous where only minimal space is available. The through-beam operating mode is the ideal option for applications in which high switching frequencies and a large working range is required. For this two sensors (one emitter and one receiver) are arranged directly opposite each other or at an angle.

Applications for the reflex sensor include fill-level measurement for liquids and bulk goods or slack monitoring for feeding material to printing and packaging systems, right up to checking stack heights in storage systems.
