SHARP TECHNOLOGY pressure sensors for liquid level measurement. Submersible static pressure level transmitters (level gauges) operate on the principle that the static pressure of the measured liquid is proportional to its height. They use advanced imported isolated diffused silicon sensing elements or ceramic capacitive pressure sensors to convert static pressure into electrical signals. These signals undergo temperature compensation and linearization to produce standard electrical signals (typically 4 to 20mA/15VDC).

SHARP TECHNOLOGY sensor operating principle

Optical measurement and control systems vary widely depending on the operating principle of how luminous flux affects photoelectric elements. Based on the nature of the output from the photoelectric element (optical measurement and control system), they are classified into two categories: analog photoelectric sensors and pulse (switching) photoelectric sensors. Analog photoelectric sensors convert the measured variable into a continuously changing photocurrent, maintaining a single-valued relationship with the measured variable. Depending on the method of measuring the target object, analog photoelectric sensors are divided into three types: transmission (absorption), diffuse reflection, and beam obstruction (shading). Transmission type refers to placing the measured object in the optical path; light energy from a constant source passes through the object, and after partial absorption, the transmitted light strikes the photoelectric element. Diffuse reflection type refers to light from a constant source striking the measured object and reflecting off its surface onto the photoelectric element. Beam obstruction type refers to the measured object blocking part of the luminous flux from the light source, thereby changing the amount of light reaching the photoelectric element; the degree of change depends on the position of the object in the optical path.

SHARP TECHNOLOGY sensor features

1) Long detection distance: By maintaining a detection distance of 10m or more in through-beam configurations, it achieves long-range detection impossible with other methods (such as magnetic or ultrasonic). 2) Few restrictions on detected objects: Since detection relies on shading and reflection caused by the object, unlike proximity sensors that are limited to metal objects, it can detect almost any object, including glass, plastic, wood, and liquids. 3) Short response time: Light itself travels at high speed, and the sensor circuitry consists entirely of electronic components without mechanical moving parts, resulting in very short response times. 4) High resolution: Advanced design techniques focus the emitted light beam into a small spot, or specialized receiving optical systems are used to achieve high resolution. This allows for the detection of tiny objects and high-precision position detection. 5) Non-contact detection: Detection occurs 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 incident light and the color of the object. This property allows for color detection. 7) Easy adjustment: In types emitting visible light, the beam is visible to the eye, facilitating easy adjustment of the sensor's position relative to the detected object.

SHARP TECHNOLOGY 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 variable into a continuously changing photocurrent. These are 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 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 widely used not only in civil industry but also hold significant importance 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 variable 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 darkness. 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.
