Touch probes, Scale Shot System (absolute)

A touch probe is a device used in measurement technology to measure distances, positions or surfaces. It is frequently used in industry, particularly in manufacturing and quality control.

A touch probe usually consists of a probe tip that is placed on the object to be measured, a spring system that returns the probe tip to an initial position, and a sensor that detects the movement of the probe tip. The sensor can, for example, be a mechanical switch, an optical sensor or a contactless sensor.

The function of the measuring probe is based on the principle of mechanical adjustment. When the probe tip is placed on the object to be measured, it yields under the influence of the spring mechanism. The sensor detects this movement and converts it into an electrical signal that can then be measured. Based on the known attributes of the spring system, the measured variable, such as the distance or position, can be calculated.

Touch probes are used in many applications, such as in the machine tool industry for position measurement, in the automotive industry for quality control of components or in medical technology for measuring tissue or body surfaces.

The Scale Shot system offers several advantages compared to other absolute-type probes:

1. Faster measuring speed: The Scale Shot System enables faster measurement as it records the data directly during the movement of the measuring head. This shortens the measuring time and increases productivity.

2. Higher accuracy: Direct measurement during movement of the measuring head results in greater accuracy. The system minimizes possible errors caused by vibrations or movements of the workpiece.

3. No reference positioning required: Unlike other absolute-type probes, the Scale Shot system does not require reference positioning before each measurement. This saves time and increases efficiency.

4. Simple operation: The Scale Shot system is easy to use and requires no complex adjustments or calibrations. It can be set up quickly and is therefore ideal for use in production environments.

5. Longer battery life: The Scale Shot System has an optimized power supply that enables a longer battery life. This makes it possible to carry out longer measurements without having to change the batteries.

Overall, the Scale Shot system offers greater speed, accuracy, ease of use and efficiency compared to other absolute type probes. It is an ideal solution for various applications in manufacturing and quality control.

The Scale Shot System is a measuring system used in surveying technology to carry out precise measurements of lengths and distances. It is based on the use of a scale that is marked at fixed intervals.

The system works by placing a scale along the distance to be measured. A high-precision measuring device, such as a laser range finder, is then used to measure the distances between the markings on the scale. The measured values are then used to calculate the total length or distance.

The accuracy class that can be achieved with the Scale Shot System depends on various factors, such as the quality of the scale, the accuracy of the measuring device and the careful execution of the measurements. As a rule, an accuracy of around ±0.1 mm per meter can be achieved. This means that for a measurement of 10 meters, the actual length can be determined with an accuracy of ±1 mm.

However, it is important to note that the accuracy of the Scale Shot system can also be affected by external influences such as temperature changes or vibrations. It is therefore important to ensure the correct environmental conditions during measurements and to take appropriate precautions to minimize possible sources of error.

There are different types of probes in addition to the absolute type with scale shot system. Some of them are:

1. Incremental type: These probes measure the difference between two consecutive positions. They therefore only provide relative measured values and not absolute values.

2. Differential type: These probes measure the difference between two measuring points. They are often used to measure the thickness of materials or the deviations between two surfaces.

3. Inductive measuring probe: These probes use an inductive coil to measure the position or deviation of an object. They react to metallic objects and can be used for various applications, e.g. for measuring distances or for position detection.

4. Capacitive measuring probe: These probes use the change in capacitance between the probe and the measured object to measure the position or deviation. They can be used for precise measurements of small distances or thicknesses.

5. Optical measuring probe: These touch probes use light beams to measure the position or deviation of an object. They often work with laser technology or optical sensors and can be used for precise measurements in various applications.

6. Ultrasonic measuring probe: These probes use sound waves to measure the position or deviation. They are frequently used in industry, e.g. for measuring the level of liquids or for distance measurement.

These are just a few examples of different types of probes. There are many other variants and specialized probes for specific applications.

Calibration and maintenance of a touch probe with a scale shot system usually takes place in several steps:

1. Preparation: Ensure that the measuring probe is properly mounted and connected to the measuring device.

2. Zero point: Adjust the zero point of the probe to ensure that it is correctly calibrated to zero. This can be done by pressing the zero point button on the measuring device.

3. Calibration: Carry out a calibration to ensure that the probe provides accurate measurements. This can be done either manually, using a calibration plate, or automatically by the meter itself.

4. Checking the measurement accuracy: Check the measuring accuracy regularly to ensure that the probe continues to provide accurate results. This can be done by comparative measurements with a known standard.

5. Cleaning and maintenance: Clean the measuring probe regularly to ensure that it is free of dirt and deposits. Also regularly check the mechanical parts of the probe for wear or damage and replace them if necessary.

It is important to follow the specific instructions of the probe and meter manufacturer, as the exact steps and requirements may vary depending on the model and manufacturer.

A touch probe with a scale shot system should ideally have the following attributes in order to meet the requirements of different measuring tasks:

1. High measuring accuracy: The measuring probe should have a high degree of accuracy in order to be able to carry out precise measurements.

2. Large measuring range: In order to be able to cover various measuring tasks, the touch probe should have a large measuring range that can detect both small and large parts.

3. Fast measuring speed: A fast measuring system enables measurements to be carried out efficiently and saves time.

4. Repeatability: The probe should have a high repeatability in order to provide consistent measurement results.

5. Simple operation: A user-friendly design and simple operation make the probe easier to use and minimize potential sources of error.

6. Robust housing: A robust housing protects the probe from damage and ensures a long service life.

7. Compatibility with various measuring devices: The measuring probe should be compatible with various measuring devices to enable flexible use.

8. Calibratability: To maintain measurement accuracy, the probe should be calibratable and be able to be checked regularly.

9. Data output: The probe should be able to output measurement data, either via an interface to a measuring device or via a wireless connection to a computer or other output device.

10. Versatility: The probe should be able to be used for various measuring tasks, such as length measurements, depth measurements, diameter or roughness measurements.

The cost of a touch probe with Scale Shot System can vary depending on the manufacturer, model and specific functions. In general, however, they tend to be more expensive than conventional probes without a scale shot system.

The Scale Shot System is an advanced technology that enables high-precision measurement. It is often used in high-quality touch probes that are used for demanding applications such as quality control in manufacturing or the measurement of high-precision workpieces.

As the Scale Shot System offers additional functionality and accuracy, the cost of such probes is generally higher than for conventional probes. Depending on the manufacturer and model, prices can range from a few hundred euros to several thousand euros.

It is important to note that the cost of a probe with a scale shot system may be justified if you require high accuracy and precision. It is advisable to compare different models and prices and consider your specific requirements before making a decision.
