BS30WP sound level measuring device

Versatile sound level measuring device as appSensor controlled via smartphone

Noise hazard measurements at the workplace
Determination of ambient noise
Checking the efficiency of noise protection measures

The appSensor BS30WP is a sound level measuring device permitting the quick and easy measurement of the volume of ambient sounds when used in combination with the MultiMeasure Mobile app.

The sound level measuring device BS30WP impresses with a high measurement sensitivity and hence particularly recommends itself for the precise determination even of low sound levels starting at 30 and ranging up to 130 dB(A). The measuring device is immediately ready for use, it can be connected to the app without the slightest effort and then displays all the measured values on the mobile terminal device.

Owing to the clever combination of the appSensor and the appertaining, free MultiMeasure Mobile app users benefit from numerous practical advantages in terms of flexibility, analysis functions, data control and documentation.

You can for instance easily display calculated minimum, maximum and average values for the sound levels determined by the measuring device and transferred to the app. Also you can set individual limit values; exceeding or falling below these thresholds automatically triggers an acoustic alarm.

Use the BS30WP's logging function to record series measurements, compare the determined data directly on your mobile terminal device or use the measured values for differentiated on-site analyses.

For use in measuring environments with roaring wind an additional plug-on wind shield is included in the scope of delivery, which suppresses disturbing wind noise but simultaneously does not impair the sound level measurement.

What is an appSensor?

Trotec appSensor

Trotec appSensors are compact precision measuring devices with high-quality sensors. Designed in a way to save space and energy, they have neither display unit nor evaluation electronics – data analysis and operation are realized almost entirely by means of the connected smartphone. Combined with the free app MultiMeasure Mobile this measuring device concept offers many compelling advantages.

All of Trotec's appSensors offer the following advantages:

  • Professional sensors for precise measuring results
  • Foolproof connection of the app via Bluetooth with visual connection confirmation by means of an LED at the device
  • Wireless control of the measuring devices and display of data via app
  • Simple measured value detection even at remote locations since the values do not have to be read directly from the measuring device
  • Additional determination and indication of minimum, maximum and average values
  • Hold, logging and alarm functions
  • Wrist strap for safe handling included in the scope of delivery
  • Practice-optimized German industrial design – protected design patent

Why use appSensors? Aren't there a lot of measuring apps already?

Of course there are numerous apps using the electronic components integrated in smartphones, e.g. microphone, gyroscope or camera, for measurements and derived calculations. But these components haven't been designed for precise metrological inspections, instead mainly for an optimized application on a mobile device.

Hence, the obtained results are not in the least comparable with the results achieved by sensors specifically designed for measuring applications. Besides, your smartphone may not be equipped with the suitable electronic component for every measurement task, e.g. for contact moisture measurements or non-contact temperature measurements.

Trotec appSensors on the other hand house professional sensors for precise measuring results –which is just what they were made for. So, be smart and use the clever combination of appSensor and MultiMeasure Mobile – our free app available for both iOS and Android – to carry out professional measurements.

The appSensor BS30WP is automatically identified by MultiMeasure Mobile.
Simple Bluetooth connection to MultiMeasure Mobile
A value measured by the BS30WP can be read clearly when displayed by the MultiMeasure Mobile app.
Numeric display of measured values
By tapping on the screen you can switch between graphic and numeric display.
Chart representation of measured values
By means of the logging function you can record measurement series and generate reports while still on site.
