German OFFICINE sensors OFFICINE models OFFICINE prices

OFFICINE sensors are sensors that measure the operating speed of the measured object and convert it into an output signal. Speed sensors include linear speed sensors and rotational speed sensors. With technological development, traditional measurement equipment can no longer meet current needs and is gradually being phased out, while laser speed sensors are widely used and play an important role in product manufacturing. By connecting to a computer, they enable automated and intelligent measurement control of the measured object. This is the product of the combination of modern measurement technology and computer technology.

OFFICINE sensor principle

Optical measurement and control systems manufactured based on different principles of luminous flux action on photoelectric elements are diverse. According to the nature of the output quantity of 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, exhibiting a single-valued relationship with the measured quantity. Analog photoelectric sensors can be divided into three major categories based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and light-blocking (beam interruption) type. The transmission type refers to placing the measured object in the optical path, where light energy emitted by a constant light source passes through the measured object, is partially absorbed, and the transmitted light is projected onto the photoelectric element. The diffuse reflection type refers to light emitted by a constant light source being projected onto the measured object, reflecting off its surface, and then being projected onto the photoelectric element. The light-blocking type refers to the measured object blocking part of the luminous flux emitted by the light source, causing a change in the luminous flux projected onto the photoelectric element; the degree of change depends on the position of the measured object in the optical path.

OFFICINE sensor features

1) Long detection distance: If a detection distance of 10m or more is maintained in through-beam configurations, it enables long-distance detection that other methods (magnetic, ultrasonic, etc.) cannot achieve. 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 all objects such as glass, plastic, wood, and liquids. 3) Short response time: Light itself is high-speed, and the sensor circuit consists of electronic components, excluding mechanical operating time, resulting in a very short response time. 4) High resolution: Advanced design techniques concentrate 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: Detection can be achieved without mechanical contact with the object, preventing damage to both the object and the sensor, thus enabling long-term use. 6) Color discrimination: The reflectance and absorptance 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 light beam is visible to the eye, facilitating adjustment of the detected object's position.

OFFICINE sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. According to the nature of the output quantity, they can be 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 lux meters for measuring light intensity, photoelectric pyrometers, photoelectric colorimeters and turbidimeters, photoelectric fire alarms, and automatic inspection devices and instruments for checking the diameter, length, ovality, and surface roughness of machined 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 outputting "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 electronic computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
