German COLOSIO sensor COLOSIO model COLOSIO price

COLOSIO 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 as pressure sensors, speed sensors, temperature sensors, etc., and serve as parts and accessories for measurement, control instruments, and equipment.

COLOSIO sensor classification

1) Non-contact torque sensor In a non-contact torque sensor, the input shaft and output shaft are connected by a torsion bar. The input shaft has splines, and the output shaft has keyways. When the torsion bar twists under the torque applied by the steering wheel, the relative position between the splines on the input shaft and the keyways on the output shaft changes. The change in relative displacement between the splines and keyways equals the twist of the torsion bar, which alters the magnetic flux density on the splines. This change in magnetic flux density is converted into a voltage signal via coils. Due to their non-contact operating mode, non-contact torque sensors offer long service life, high reliability, resistance to wear, lower latency, and reduced sensitivity to shaft deflection and axial offset. They are widely used in the passenger car sector. Common types of non-contact torque sensors include strain-gauge, magneto-electric, fiber-optic, and photoelectric sensors. Strain-gauge non-contact sensors utilize wireless transmission technology. With advancements in technology and wireless transmission, the conductive slip rings and brush arms previously used for output signals in contact-type strain gauge sensors can now be replaced by wireless transmission modules. This overcomes wear between slip rings and brush arms, improving measurement accuracy. Magneto-electric torque sensors operate on the principle of magneto-electric conversion, analyzing the phase difference between two output electromotive force signals to measure torque. They are mainly divided into closed-magnetic-circuit and open-magnetic-circuit sensors. Fiber-optic torque sensors primarily use light reflection and phase difference principles. They read light signals reflected from two corresponding positions on the shaft, calculate the phase difference, and thereby determine the corresponding torque value. However, fiber-optic sensors are susceptible to environmental influences, and their installation and debugging are relatively difficult. Photoelectric torque sensors use photoelectric sensing elements as core components. When torque is applied to the drive shaft, the intensity of light emitted by the source changes accordingly, causing a change in the output current of the photoelectric element. Measuring this change allows calculation of the torque value. [3] 2) Strain gauge torque sensor Strain gauge torque measurement employs strain electrical measurement technology. Strain gauges are bonded to the elastic shaft to form a measurement bridge. When the elastic shaft undergoes slight deformation due to torque, the resistance of the bridge changes. This change in resistance is converted into an electrical signal, thereby achieving torque measurement. The sensor performs the following information conversion: it consists of an elastic shaft, a measurement bridge, an instrumentation amplifier, and an interface circuit. 3) High-performance wireless sensor High-performance wireless torque sensors integrate sensors with wireless communication technology to achieve wireless data transmission. The torque electrical signal is amplified and undergoes A/D conversion by a microcontroller-controlled signal processing circuit. An encoder then encodes the collected digital data and sends it to a transmission module. Upon receiving the data, the reception module's decoder translates the data and sends it to the microcontroller, which displays the resulting torque data value via LED. The sensor data acquisition and transmission circuit consists of the torque sensor, signal processing section, microcontroller, and wireless transmission circuit. The torque sensor transmits the strain electrical signal generated by the resistance strain gauges to the signal processing circuit. The signal processing section extracts and amplifies the sensor's analog signal and performs analog-to-digital conversion. The microprocessor controls the operation of various components within the system and processes the digital signals. Under the control of the microprocessor, the wireless transmission circuit uses an encoder to encode and process the collected information data, which is then transmitted by the emission module, achieving wireless transmission. 4) Electronic sensor An electronic torque meter is a portable, high-performance shaft power measuring instrument designed for fan and pump testing and on-site energy efficiency evaluation. Innovatively, the electronic torque meter eliminates the cumbersome, complex, and often impractical installation process associated with traditional electromechanical torque sensors in many field environments. It enables real-time measurement of fan and pump motor efficiency, monitors the operational status of fan and pump motors at various stages during use, and provides real-time, authentic, and reliable data for studying their usage conditions. This avoids impacts on test results caused by improper installation of electromechanical torque sensors. The electronic torque meter can completely replace the shaft power measurement function of traditional torque sensors and obtain real-time efficiency of fan and pump motors, providing a rigorous and scientific evaluation method for energy saving in fan and pump units.

COLOSIO sensor usage precautions

1) During installation, do not operate while energized. Do not directly strike or collide with the sensor. 2) Tighten the coupling's fastening bolts securely. Install a protective cover over the outside of the coupling to prevent personal injury. 3) The signal line output must not be grounded or short-circuited to the power supply. The output current must not exceed 10mA. The shield layer of the shielded cable must be connected to the common terminal (power ground) of the +15V power supply. 4) In routine metrological verification and calibration work, torque sensors are typically calibrated using a torque standard machine. Since torque sensors have high accuracy, usually Class 1 and above, another important factor affecting measurement results, besides the uncertainty of the torque standard machine itself, is the connection quality between the sensor and the torque standard machine. Especially in the calibration of high-precision torque sensors, when not considering the uncertainty of the torque standard machine itself, the quality of the connection directly affects the accuracy of the measurement results. In existing torque sensor measurement methods, sensors are usually connected in series with the torque standard machine for calibration. Therefore, issues regarding the reliability of connection quality inevitably arise during calibration. In the past, to ensure stability and firmness of the connection installation, rigid connections were typically used. This method caused considerable inconvenience for inspection personnel during assembly and disassembly. Additionally, due to the machining precision of components and the existence of fit clearances, the coaxiality between the measurement shaft systems changed significantly during actual measurement, seriously affecting the accuracy of the results. Although this defect can be reduced using laser alignment devices, influenced by various factors and differences in manual installation skills, coaxiality remains a significant source of uncertainty in the metrology process during actual loading of the torque sensor.
