German ANDERSON NEGELE sensors, ANDERSON NEGELE models, ANDERSON NEGELE prices

ANDERSON NEGELE sensors are sensors that use laser technology for measurement. They consist of a laser emitter, a laser detector, and a measurement circuit. Laser sensors are a new type of measuring instrument; their advantages include the ability to perform non-contact long-distance measurement, high speed, high precision, large measuring range, and strong resistance to optical and electrical interference.

ANDERSON NEGELE sensor features

1) Since detection is performed in a non-contact manner, there is no wear or damage to the object being detected. 2) Since a contactless output method is used, service life is extended (except for magnetic types); semiconductor output is used, which has no effect on contact life. 3) Unlike optical detection methods, these sensors are suitable for use in environments with water and oil, as detection is hardly affected by stains, oil, or water on the object being detected. In addition, products with PTFE housings and good chemical resistance are available. 4) Compared with contact switches, high-speed response can be achieved. 5) Capable of operating over a wide temperature range. 6) Detection is based on changes in the physical properties of the object being detected and is not affected by the color of the object, so it is hardly influenced by surface color, etc. 7) Unlike contact types, these sensors are affected by ambient temperature, surrounding objects, and other similar sensors, including mutual influence between inductive and capacitive sensors. Therefore, mutual interference must be considered during sensor installation. In addition, for inductive types, the influence of surrounding metal must be considered, while for capacitive types, the influence of surrounding objects must be considered.

ANDERSON NEGELE sensor selection principles

1) Selection of sensitivity: Generally, within the linear range of the sensor, higher sensitivity is preferred. Only when sensitivity is high is the output signal value corresponding to the change in the measured variable relatively large, which is beneficial for signal processing. However, it should be noted that high sensor sensitivity also makes it easier for external noise unrelated to the measured variable to mix in and be amplified by the amplification system, affecting measurement accuracy. Therefore, the sensor itself should have a high signal-to-noise ratio to minimize interference signals introduced from the outside. Sensor sensitivity is directional. When the measured variable is a single vector and high directionality is required, a sensor with low sensitivity in other directions should be selected; if the measured variable is a multi-dimensional vector, the cross-sensitivity of the sensor should be as small as possible. 2) Frequency response characteristics: The frequency response characteristics of the sensor determine the frequency range of the measured variable, and distortion must be maintained within the allowable frequency range. In practice, sensor response always has a certain delay, and shorter delay times are preferred. The higher the frequency response of the sensor, the wider the measurable signal frequency range. In dynamic measurements, response characteristics should be selected according to the characteristics of the signal (steady-state, transient, random, etc.) to avoid excessive errors. 3) Linear range: The linear range of a sensor refers to the range where the output is proportional to the input. Theoretically, within this range, sensitivity remains constant. The wider the linear range of the sensor, the larger its measuring range, and it can ensure a certain measurement accuracy. When selecting a sensor, once the type of sensor is determined, the first thing to check is whether its measuring range meets the requirements. However, in reality, no sensor can guarantee absolute linearity, and its linearity is relative. When the required measurement accuracy is relatively low, a sensor with small non-linear error can be approximated as linear within a certain range, which brings great convenience to measurement. 4) Stability: The ability of a sensor to maintain its performance unchanged after a period of use is called stability. Factors affecting the long-term stability of a sensor, besides the sensor's own structure, are mainly the sensor's operating environment. Therefore, to ensure good stability, the sensor must have strong environmental adaptability. Before selecting a sensor, its operating environment should be investigated, and a suitable sensor should be selected according to the specific operating environment, or appropriate measures should be taken to reduce environmental impact. Sensor stability has quantitative indicators; after exceeding the service life, recalibration should be performed before use to determine whether the sensor's performance has changed. In some applications where the sensor needs to be used for a long time and cannot be easily replaced or calibrated, stricter stability requirements are imposed on the selected sensor, requiring it to withstand long-term testing. 5) Accuracy: Accuracy is an important performance indicator of a sensor and is a key link related to the measurement accuracy of the entire measurement system. The higher the accuracy of the sensor, the more expensive its price. Therefore, the accuracy of the sensor only needs to meet the accuracy requirements of the entire measurement system, and it is not necessary to select excessively high accuracy. This allows for the selection of cheaper and simpler sensors among many sensors that meet the same measurement purpose, such as Atlas air compressor parts. If the measurement purpose is qualitative analysis, a sensor with high repeatability accuracy can be selected, and it is not advisable to select one with high absolute value accuracy; if it is for quantitative analysis and precise measurement values must be obtained, a sensor with an accuracy grade that meets the requirements must be selected. For certain special application scenarios where a suitable sensor cannot be selected, it is necessary to design and manufacture the sensor yourself. The performance of self-made sensors should meet the usage requirements.

ANDERSON NEGELE sensor usage precautions

1) High-temperature environments can cause problems for sensors, such as melting of coating materials, opening of solder joints, and structural changes due to internal stress in the elastic body. Sensors working in high-temperature environments often use high-temperature resistant sensors; in addition, devices such as heat insulation, water cooling, or air cooling must be added. 2) Dust and moisture can cause short-circuit effects on sensors. In such environmental conditions, sensors with high sealing should be selected. Different sensors have different sealing methods, and their sealing properties vary greatly. Common sealing methods include filling or coating with sealant; mechanical fastening sealing with rubber gaskets; welding (argon arc welding, plasma beam welding) and vacuum nitrogen-filled sealing. In terms of sealing effectiveness, welded sealing is the best, and filled/coated sealant is the worst. For sensors working in clean, dry indoor environments, sensors with adhesive sealant sealing can be selected, while for sensors working in environments with high humidity and dust, sensors with diaphragm heat-shrink sealing, diaphragm welding sealing, or vacuum nitrogen-filled sealing should be selected. 3) In highly corrosive environments, such as humidity and acidity, which can damage the elastic body of the sensor or cause short circuits, sensors with plastic-sprayed outer surfaces or stainless steel housings, which offer good corrosion resistance and good sealing, should be selected. 4) Electromagnetic fields can cause chaotic output signals from sensors. In this case, the shielding of the sensor should be strictly checked to see if it has good electromagnetic immunity. 5) Flammable and explosive environments not only cause complete damage to sensors but also pose a significant threat to other equipment and personal safety. Therefore, sensors working in flammable and explosive environments have higher requirements for explosion-proof performance: in flammable and explosive environments, explosion-proof sensors must be selected. The sealed housing of such sensors must consider not only its sealing but also its explosion-proof strength, as well as the waterproof, moisture-proof, and explosion-proof properties of the cable lead-outs.
