German GESA THERMOMETERS sensor, GESA THERMOMETERS model, GESA THERMOMETERS price

GESA THERMOMETERS sensors, also known as linear sensors, are linear devices based on metallic induction. The function of the sensor is to convert various measured physical quantities into electrical signals. In production processes, displacement measurement is generally divided into two types: measuring physical dimensions and mechanical displacement. Depending on the form of transformation of the measured variable, displacement sensors can be classified into analog and digital types. Analog types can be further divided into property-based and structural types. Commonly used displacement sensors are predominantly analog structural types, including potentiometric displacement sensors, inductive displacement sensors, synchros, capacitive displacement sensors, eddy current displacement sensors, and Hall effect displacement sensors. An important advantage of digital displacement sensors is that they facilitate direct input of signals into computer systems. These sensors are developing rapidly and their applications are becoming increasingly widespread.

GESA THERMOMETERS sensor principle

Optical measurement and control systems vary widely depending on the principle of action of luminous flux 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, exhibiting a single-valued relationship with the measured quantity. Analog photoelectric sensors can be classified into three major types based on the method of measuring the target object: transmission (absorption) type, diffuse reflection type, and beam-blocking (light beam obstruction) type. The transmission type refers to placing the measured object in the optical path, where light energy from a constant light 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 beam-blocking type refers to the scenario where the measured object obstructs 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 position of the object in the optical path.

GESA THERMOMETERS 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 all objects such as 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 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 possible: Detection is achieved without mechanical contact with the object, preventing damage to both the object and the sensor, thereby enabling long-term use. 6) Color discrimination possible: The reflectance and absorptance of light formed by the detected object vary depending on the wavelength of the incident 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 adjustment of the detected object's position.

GESA THERMOMETERS sensor applications

Photoelectric sensors using photoelectric elements as sensitive components are diverse and widely used. They can be classified into two categories based on the nature of the output: (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, 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 to output "on" or "off" electrical signals when exposed to light or no light. Photoelectric elements serve as switching photoelectric conversion components. Examples include photoelectric inputs for computers, switching temperature control devices, and digital photoelectric tachometers for speed measurement.
