German bd sensor sensor bd sensor model bd sensor price

bd sensor sensors are components that convert changes in non-electrical quantities (such as speed and pressure) into changes in electrical quantities. Depending on the non-electrical quantity being converted, they can be classified into pressure sensors, speed sensors, temperature sensors, etc., and serve as parts and accessories for measurement and control instruments and equipment.

bd sensor sensor features

1) Non-contact detection prevents wear and damage to the object being detected. 2) The use of contactless output extends service life (except for magnetic types); semiconductor output 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. Products with PTFE housings and good chemical resistance are also available. 4) Compared to contact switches, high-speed response is achievable. 5) Capable of operating across a wide temperature range. 6) Detection is based on changes in the physical properties of the object, independent of its color, so it is hardly affected by surface color. 7) Unlike contact types, these sensors are influenced by ambient temperature, surrounding objects, and other sensors of the same type, including inductive and capacitive types, which can cause mutual interference. Therefore, mutual interference must be considered during sensor installation. Additionally, for inductive types, the influence of surrounding metal must be considered, while for capacitive types, the influence of surrounding objects must be taken into account.

bd sensor sensor selection principles

1) Sensitivity selection: Generally, within the linear range of the sensor, higher sensitivity is preferred. High sensitivity ensures a larger output signal corresponding to changes in the measured variable, facilitating signal processing. However, note that high sensor sensitivity also makes it easier for external noise unrelated to the measured variable to mix in and be amplified by the 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. If the measured variable is a single vector with strict directional requirements, choose a sensor with low sensitivity in other directions; if the measured variable is a multi-dimensional vector, the cross-sensitivity of the sensor should be as low as possible. 2) Frequency response characteristics: The frequency response characteristics of a sensor determine the frequency range of the measured variable, which must remain undistorted within the allowable frequency range. In practice, sensor response always involves some 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 signal characteristics (steady-state, transient, random, etc.) to avoid excessive errors. 3) Linear range: The linear range of a sensor refers to the range where output is proportional to input. Theoretically, sensitivity remains constant within this range. A wider linear range implies a larger measuring range and ensures a certain level of measurement accuracy. When selecting a sensor, once the type is determined, the first step is to check whether its measuring range meets the requirements. In reality, no sensor can guarantee absolute linearity; linearity is relative. When the required measurement accuracy is relatively low, sensors with small nonlinear errors can be approximated as linear within a certain range, which greatly facilitates measurement. 4) Stability: Stability refers to the ability of a sensor to maintain its performance over time. Factors affecting long-term stability, apart from the sensor's own structure, are primarily the operating environment. Therefore, to ensure good stability, the sensor must have strong environmental adaptability. Before selecting a sensor, investigate its operating environment and choose a suitable sensor or take appropriate measures to reduce environmental impact. Sensor stability has quantitative indicators; after exceeding the service period, recalibration should be performed before use to determine if performance has changed. In applications requiring long-term use where replacement or recalibration is difficult, stricter stability requirements apply, and the sensor must withstand long-term testing. 5) Accuracy: Accuracy is an important performance indicator for sensors and a key factor affecting the measurement accuracy of the entire system. Higher sensor accuracy comes at a higher cost, so the sensor's accuracy only needs to meet the requirements of the entire measurement system; excessively high accuracy is unnecessary. This allows for the selection of cheaper and simpler sensors among those meeting the same measurement purpose, such as Atlas air compressor spare parts. If the measurement purpose is qualitative analysis, a sensor with high repeatability accuracy is sufficient, and high absolute value accuracy is not required; for quantitative analysis requiring precise measurement values, a sensor with an accuracy grade that meets the requirements must be selected. For certain special applications where no suitable sensor is available, custom design and manufacturing may be necessary. The performance of custom-made sensors must meet usage requirements.

bd sensor sensor usage precautions

1) High-temperature environments can cause issues such as melting of coating materials, opening of solder joints, and structural changes due to internal stress in the elastic body. Sensors operating in high-temperature environments often use high-temperature-resistant sensors; additionally, insulation, water cooling, or air cooling devices must be added. 2) Dust and moisture can cause short circuits in sensors. In such environmental conditions, sensors with high sealing ratings should be selected. Sealing methods vary among different sensors, resulting in significant differences in sealing effectiveness. Common sealing methods include filling or coating with sealant, mechanical fastening with rubber gaskets, welding (argon arc welding, plasma beam welding), and vacuum nitrogen filling. In terms of sealing effectiveness, welded sealing is the best, while filled/coated sealant is the worst. For sensors working in clean, dry indoor environments, coated sealant sensors can be chosen, while for sensors working in humid, high-dust environments, diaphragm heat-shrink sealing, diaphragm welding sealing, or vacuum nitrogen-filled sensors should be selected. 3) In highly corrosive environments, such as humidity and acidity, which can damage the elastic body or cause short circuits, choose sensors with powder-coated or stainless steel housings that offer good corrosion resistance and sealing. 4) Electromagnetic fields can cause chaotic output signals from sensors. In such cases, strictly check the sensor's shielding to ensure it has good electromagnetic immunity. 5) Flammable and explosive environments not only cause complete damage to sensors but also pose significant threats to other equipment and personal safety. Therefore, sensors working in flammable and explosive environments have higher requirements for explosion-proof performance: in such environments, explosion-proof sensors must be selected. The sealed housing of these sensors must consider not only sealing but also explosion-proof strength, as well as the waterproof, moisture-proof, and explosion-proof properties of cable outlets.
