microsonic pico+TF ultrasonic sensor

The pico+TF sensors are the smallest chemically resistant ultrasonic sensors available from microsonic. With four different detection ranges, they cover a measurement range from 20 mm to 1.3 m and are available with both analog and switching outputs and an IO-Link interface. The analog output versions are available with a voltage output of 0–10 V and a current output of 4–20 mA. Each sensor with IO-Link can communicate with the IO-Link master via the IO-Link interface in a digital point-to-point connection below the field level.

The compact dimensions of the sensors makes them suitable for distance measurement in restricted installation contexts. The ultrasonic transformer is protected by PTFE film while the exterior PVDF coating with its M22 x 1.5 external thread seals the ultrasonic transformer from the sensor housing, allowing their use in surroundings with an overpressure of up to 3 bar.

A typical application for the ultrasonic sensors is fill level monitoring of aggressive paints and inks such as those used in the digital printing sector, which often contain ketone. The sensors can be used at an operating temperature of between -25°C and +75°C.

The sensors are fitted with the microsonic teach-in function to enable all settings. This makes the ultrasonic sensors adaptable and suitable for a range of applications. The flexible filter settings are also used for fill level monitoring, with an internal ‘averaging filter’ setting that enables the compensation of peaks caused by waves and ripples.
