Digital sensors are becoming increasingly common in metrology. But what exactly is a digital sensor, how does it work and what are its practical benefits? Here we cover the basics. <\/strong><\/p>\n\n\n\n

What is a digital sensor?<\/h3>\n\n\n\n

A digital sensor is a sensor that measures, for example, temperature or humidity and sends the measured values as digital information to an instrument or a data logger. The sensor processes the measurement data itself and sends ready-to-use values, providing fast and reliable readings in the instrument. Analog sensors instead send a continuous current or voltage signal that the instrument must interpret.<\/p>\n\n\n\n

Why do digital sensors provide better accuracy?<\/h3>\n\n\n\n

What makes digital sensors particularly accurate is that both the measurement and the interpretation take place in the sensor. With analog sensors, accuracy is determined by both the instrument and the sensor, and measurement data can be affected by electrical noise or voltage drops on the way to the instrument before the signal is interpreted. Because digital sensors send ready-to-use values, measurements remain stable all the way from sensor to instrument.<\/p>\n\n\n\n

Digital technology also allows for higher resolution, often with more decimal places. The result is more reliable and comparable measurements, reducing the need to re-measure. <\/p>\n\n\n\n

What are the main benefits of digital sensors?<\/h3>\n\n\n\n
    \n
  • Easy integration and more stable measurement<\/strong>
    The instrument automatically recognizes the sensor type and receives ready-to-use measurement values directly. This provides higher accuracy and reduces the risk of both misalignment and incorrect readings.

    <\/li>\n\n\n\n
  • Flexibility<\/strong>
    Digital transducers can be seamlessly integrated into instruments and measurement systems that support different transducer types or multiple measurement channels. Most of Testo’s digital transducers use the same type of connector, making it easy to connect and switch between different transducer types in the same instrument.

    <\/li>\n\n\n\n
  • Easy identification<\/strong>
    Digital sensors have unique serial numbers, which simplifies tracking and management of the measuring equipment. Each transducer is calibrated as a separate unit and has its own calibration document (easily accessed by scanning a QR code on the transducer once it has been calibrated with us).

    <\/li>\n\n\n\n
  • Calibrate without pausing measurements<\/strong>
    Since digital sensors are calibrated separately, you can send the sensor for calibration without having to send the entire instrument. Therefore, by replacing the sensor, you can continue your measurements even when a sensor needs calibration.
