German RASKIN OSTERMANN sensors, RASKIN OSTERMANN models, RASKIN OSTERMANN prices

RASKIN OSTERMANN 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 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.

RASKIN OSTERMANN sensor features

1) Non-contact detection prevents wear and damage to the object being detected. 2) Contactless output extends service life (except for magnetic types); semiconductor output is used, which does not affect 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. Additionally, products with PTFE housings and good chemical resistance are available. 4) Compared with contact switches, high-speed response is achievable. 5) Suitable for 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, leading to mutual interference between sensors. Therefore, mutual interference must be considered during sensor installation. For inductive types, the influence of surrounding metal must be considered, while for capacitive types, the influence of surrounding objects must be considered.

RASKIN OSTERMANN 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, high sensitivity also makes the sensor susceptible to external noise unrelated to the measured variable, which can be amplified by the system and affect measurement accuracy. Therefore, the sensor should have a high signal-to-noise ratio to minimize interference from external sources. Sensor sensitivity is directional. If the measured variable is a single vector with strict directional requirements, select a sensor with low sensitivity in other directions; if the measured variable is a multi-dimensional vector, minimal cross-sensitivity is required. 2) Frequency response characteristics: The frequency response of the sensor determines the frequency range of the measured variable, and distortion must be avoided within the allowable frequency range. In practice, sensor response always involves some delay, and shorter delay times are preferred. Higher frequency response allows for a wider measurable signal frequency range. In dynamic measurements, response characteristics should be selected based on signal features (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 certain measurement accuracy. When selecting a sensor, after determining the type, first check if the measuring range meets requirements. In reality, no sensor guarantees absolute linearity; linearity is relative. When lower measurement accuracy is acceptable, sensors with small non-linear errors can be approximated as linear within a certain range, greatly facilitating measurement. 4) Stability: Stability refers to the ability of a sensor to maintain its performance over time. Factors affecting long-term stability include the sensor's structure and, primarily, the operating environment. To ensure good stability, the sensor must have strong environmental adaptability. Before selecting a sensor, investigate the operating environment and choose a suitable sensor or take appropriate measures to reduce environmental impact. Stability has quantitative indicators; after exceeding the service period, recalibration is required before use to determine if performance has changed. In applications requiring long-term use without easy replacement or recalibration, stricter stability requirements apply, and the sensor must withstand long-term testing. 5) Accuracy: Accuracy is a key performance indicator for sensors and a critical factor in the overall measurement system's accuracy. Higher sensor accuracy comes at a higher cost, so select accuracy that meets the system's requirements without being excessively high. This allows choosing cheaper and simpler sensors among those meeting the same measurement purpose. For qualitative analysis, select sensors with high repeatability rather than high absolute accuracy; for quantitative analysis requiring precise values, select sensors with accuracy grades that meet requirements. For special applications where suitable sensors are unavailable, custom-designed sensors may be necessary, and their performance must meet usage requirements.

RASKIN OSTERMANN sensor usage precautions

1) High-temperature environments can cause coating materials to melt, solder joints to open, and structural changes due to internal stress in the elastic body. Sensors operating in high-temperature environments should be high-temperature resistant; additionally, heat insulation, water cooling, or air cooling devices must be installed. 2) Dust and moisture can cause short circuits in sensors. In such environments, select sensors with high sealing ratings. Sealing methods vary among sensors, with significant differences in sealing effectiveness. Common sealing methods include sealant filling or coating, mechanical sealing with rubber gaskets, welding (argon arc welding, plasma beam welding), and vacuum nitrogen filling. Welding provides the best sealing, while sealant filling is the least effective. For sensors operating in clean, dry indoor environments, sealant-coated sensors are suitable; for environments with high moisture and dust, select sensors with diaphragm heat-shrink sealing, diaphragm welding, or vacuum nitrogen filling. 3) In highly corrosive environments, such as those with moisture and acids that can damage the elastic body or cause short circuits, select sensors with powder-coated or stainless steel housings for good corrosion resistance and sealing. 4) Electromagnetic fields can disrupt sensor output signals. In such cases, strictly check the sensor's shielding to ensure good electromagnetic immunity. 5) Flammable and explosive environments pose severe risks to sensors, other equipment, and personal safety. Therefore, sensors operating in such environments must meet higher explosion-proof requirements: explosion-proof sensors must be used, and their sealed housings must consider sealing, explosion-proof strength, and the waterproof, moisture-proof, and explosion-proof properties of cable entries.
