Dracal PTH200 components highlighted: USB plug, sensor and wire

Sensor or Measuring Instrument: What Does Dracal Offer?

Blog
The official definition (1) of a sensor is: a device that responds to a physical stimulus and transmits a resulting impulse. It must always be used in conjunction with other electronic components in order for the signal to be interpretable. However, Dracal measuring instruments are called “sensors” in the air pressure and temperature sensor markets. […]

Calibrating Your Device: 5 Advantages of Opting for the 3-point User-Calibration Mechanism

Blog
The math channels available in our visualization and logging software allow you to implement formulas involving the various channels of Dracal USB sensors. In particular, the implementation of functions “equivalent” to a calibration can be implemented manually and be accessible in the graphing and logging tab. Why would you then choose a device (-CAL) that […]
