What Is a Displacement Sensor?
A Displacement Sensor is a device that measures the distance between the sensor and an object by detecting the amount of displacement through a variety of elements and converting it into a distance. Depending on what element is used, there are several types of sensors, such as optical displacement sensors, linear proximity sensors, and ultrasonic displacement sensors
Features
1. A physical quantity of an object can be measured.A Displacement Sensor measures and detects changes (displacement) in a physical quantity.
The Sensor can measure the height, width, and thickness of an object by determining the amount of displacement of that object.
A Measurement Sensor measures the position and dimensions of an object.
2. Physical quantity output is also possible in addition to ON/OFF signal output.
Analog output of physical quantities (current output or voltage output) can also be performed (excluding some models).
Some models also support digital (serial) communications.
High frequency radar description
1 Product Overview
1.1 Level measurement solutions
Radar level meter is a non-contact radar level meter using the pulse principle, which can be widely used to measure the distance, level, volume, weight and open channel flow of liquids, slurries and gunks, and can also be used to measure solid media such as powder, particles and blocks. Stable measurement is possible even in dusty, agitated applications.
1.2 Measurement Principle
The radar level meter transmits a narrow microwave pulse signal with very low energy through the antenna. The pulse signal is transmitted in space at the speed of light and is reflected when it meets the measured medium. The reflected signal is received by the instrument Measurement of surface distance.
Time 1: The initial pulse is generated
Time 2: Travel down the horn antenna, speed C(light speed)0%
Time 3: The pulse meets the surface of the medium and reflects
Time 4: The reflected pulse is received and recorded by the processo The time difference T between the pulse signal from being transmitted to being received is proportional to the distance D from the datum surface to the medium surface :D=CXT/2B0
When running, the material level can not enter the measurement blind area
1.3 Technical Advantages
Transmission frequencies up to 26GHz are used
High frequency and signal-to-noise ratio, is the choice of low dielectric constant media
The beam Angle is small, the energy is concentrated, and it has anti-interference ability, which greatly improves the measurement accuracy and reliability
Measurement blind area is small, for small tank measurement will also achieve the effect of short wavelength, for small particle media and tilted media surface level measurement effect is good measurement sensitive, refresh speed, antenna size is small, easy to install, firm and durable, maintenance-free
Non-contact measurement, no wear, can measure the level of liquid, solid medium is almost not affected by temperature, pressure, water steam, foam, dust and other complex conditions using two-wire circuit power supply technology, power supply voltage and output signal through a two-core cable transmission, saving costs
Using microprocessor and echo processing technology, it can be applied to various complex conditions with low transmission power, and can be installed in various metal and non-metal containers, without harm to the human environment
The display with buttons makes it easy to set the parameters of the instrument
The whole measurement system is composed of sensors (i.e. antennas) and signal converters, and has only one body structure
