UA1 series ultrasonic analysers test the performance of ultrasonic welding machines by measuring the vibration amplitude and frequency at the welding face.

UA1 series ultrasonic analysers test the performance of ultrasonic welding machines by measuring the vibration amplitude and frequency at the welding face.

The unit provides the best indication of the health and efficiency of the weld horn, booster and the transducer, also the coupling between these components.

The system comprises a small desktop instrument with a multifunction backlit LCD on the front panel.

This displays both the vibration frequency in kilohertz, and the peak to peak amplitude of the vibration in microns.

The sensor is connected to the instrument by a 2m cable, integral to the sensor only.

A pushbutton on the front panel selects between aluminium and titanium horns, and also a calibration mode, where the actual linear displacement of the sensor can be measured for calibration against a known calibration standard.

The system incorporates a universal power supply for 100 to 250V AC 50/60Hz mains power operation.

Specifications include: a linear measuring range of 0.5mm; an offset of 50um; sensitivity of 2mV/um; full-scale output of 0 to 1V DC; frequency response from 15 to 40kHz; and CE compliance.

The sensor is mounted into a handheld grip, machined form Peek bar stock.

Measurements are made by holding the sensor face to the area of interest on the Sonatrode, booster or transducer.

The system has been designed for comfortable and easy operation, with optimum efficiency in accessing the performance of the areas of interest of the horns (Sonatrodes), boosters and transducers.
