Digital measuring probes
The incremental measuring method in digital probes is based on the division of a homogeneous grid structure. Here, the position of the probe is obtained by counting individual increments (also called measuring steps), whereby the zero point (start of counting) can be set as desired. In order for this position information to have an absolute reference, there is another track on the measuring standard which carries a reference mark. This reference mark, which determines an absolute position of the scale, is assigned to exactly one signal period. Only by passing over the reference mark can an absolute reference of the position be established or the last defined reference point be approached again.

The advantage of an absolute measuring method is that the position value is available directly when the digital probe is switched on. This position is called up directly by the connected electronics, e.g. when switching on again after a power failure. This eliminates the need to retrace the axes to determine the reference point. The measuring body used in touch probes is divided into a serial code structure from which the absolute position information is determined immediately. Furthermore, a separate incremental track is interpolated for the position value and an incremental signal is also generated according to the interface version used.
What are digital probes and how do they work?
Digital measuring probes are measuring devices that are used to precisely determine lengths and distances. They are often used in areas such as production, quality assurance or in the laboratory.
Digital probes consist of a measuring head that is attached to a handle or holder. The measuring head contains a movable contact pin which is brought into contact with the object to be measured. The measurement is carried out by electronic sensors in the measuring head, which detect the distance between the contact pin and the object.
The measured values are recorded in real time and shown on a digital display. The display shows the measured length or distance in the desired unit, e.g. millimeters or inches. Digital probes can also be connected to a computer or other devices via an interface such as USB or Bluetooth in order to save or process the measurement data.
Digital probes generally offer high accuracy and repeatability. They are also easy to use and do not require manual reading or interpretation as with analog meters. Furthermore, they often offer additional functions such as zero setting, saving measured values and switching between different units.
Overall, digital probes are versatile tools that enable precise measurements and can improve efficiency and accuracy in various applications.

How are digital probes calibrated and how often should this be done?
Digital probes are usually calibrated by the manufacturer before they are delivered. This calibration process involves checking and adjusting the probe to ensure that it provides accurate measurement results.
However, the calibration of digital probes can be lost over time, especially if the probe is used frequently or subjected to high loads. The calibration should therefore be checked regularly and recalibrated if necessary.
The frequency of calibration depends on various factors, such as the frequency of use, the type of measurements and the requirements of the respective area of application. In some sectors, such as the medical or aviation industry, stricter calibration intervals may be prescribed.
As a rough guide, it is recommended that digital probes are calibrated every six to twelve months. More frequent calibration may be necessary for intensive use or critical measurements. It is important to follow the manufacturer's recommendations and have the calibration carried out by qualified personnel to ensure accurate and reliable measurement results.
