German CAPTRON sensors CAPTRON models CAPTRON prices

CAPTRON sensors, also known as torque sensors, torsion sensors, torque transducers, and torque meters, are divided into two main categories: dynamic and static. Dynamic torque sensors are also referred to as torque sensors, torque-speed sensors, non-contact torque sensors, and rotary torque sensors. Torque sensors detect the twisting moment on various rotating or non-rotating mechanical components. They convert the physical changes in torque into precise electrical signals. Torque sensors can be used in the manufacture of viscometers and electric (pneumatic, hydraulic) torque wrenches, offering advantages such as high precision, fast frequency response, good reliability, and long service life.

CAPTRON sensor principle

Optical measurement and control systems vary widely based on the different principles of how luminous flux acts on photoelectric elements. Based on the nature of the output from the photoelectric element (optical measurement and control system), they can be divided into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured quantity into a continuously changing photocurrent, maintaining a single-valued relationship with the measured quantity. Analog photoelectric sensors can be classified into three types based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam obstruction) type. The transmission type refers to placing the measured object in the optical path, where light energy from a constant source passes through the object, is partially absorbed, and the transmitted light projects onto the photoelectric element. The diffuse reflection type refers to light from a constant source projecting onto the measured object, reflecting off its surface, and then projecting onto the photoelectric element. The light-blocking type refers to the scenario where the object blocks part of the luminous flux from the light source, changing the amount of light reaching the photoelectric element; the degree of change depends on the object's position in the optical path.

CAPTRON sensor features

1) Long detection distance: By maintaining a detection distance of 10m or more in through-beam configurations, it achieves long-range detection that other methods (magnetic, ultrasonic, etc.) cannot. 2) Few restrictions on detected objects: Since the detection principle relies on light blocking and reflection caused by the object, unlike proximity sensors that limit detection to metals, it can detect almost any object, including glass, plastic, wood, and liquids. 3) Short response time: Light itself is high-speed, and the sensor circuitry consists entirely of electronic components, eliminating mechanical operating time, resulting in very short response times. 4) High resolution: Advanced design techniques focus the emitted light beam into a small spot, or special receiving optical systems are constructed to achieve high resolution. This allows for the detection of tiny objects and high-precision position detection. 5) Non-contact detection possible: Detection is achieved without mechanical contact with the object, preventing damage to both the object and the sensor, thus enabling long-term use. 6) Color discrimination possible: The reflectivity and absorptivity of light formed by the detected object vary depending on the wavelength of the emitted light and the color of the object. Utilizing this property, the color of the detected object can be determined. 7) Easy adjustment: In types emitting visible light, the beam is visible to the eye, facilitating easy adjustment of the detected object's position.

CAPTRON sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. Based on the nature of the output, they are divided into two categories: (1) Photoelectric measuring instruments that convert the measured quantity into a continuously changing photocurrent, used to measure physical quantities such as light intensity, object temperature, light transmittance, displacement, and surface condition. Examples include illuminance meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric alarms for fire prevention, and automatic inspection devices and instruments for checking the diameter, length, ovality, and surface roughness of processed parts, all of which use photoelectric elements as sensitive components. Semiconductor photoelectric elements are not only widely used in civil industrial fields but also hold an important position in military applications. For example, lead sulfide photoresistors can be used to make infrared night vision devices, infrared cameras, and infrared navigation systems; (2) Devices that convert the measured quantity into a continuously changing photocurrent. Various photoelectric automatic devices are made using the characteristic of photoelectric elements to output "present" or "absent" electrical signals when exposed to light or no light. Photoelectric elements serve as switching photoelectric conversion components. Examples include photoelectric input devices for computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
