OVERVIEW
The RBRD80 series intelligent radar level gauge is an advanced radar level measuring instrument with a measurement distance of 30 meters. It can be used for level measurement of storage tanks, intermediate buffer tanks, or process containers, and outputs 4-20mA analog signals.
FEATURES
- Adopting advanced non-contact measurement
- Made with stable materials
- Measure the level of liquid and solid media
- Can measure all media with a dielectric constant>1.8
- Measurement range 0~20m (can be extended to 30 meters)
- Adopting a two-wire system and loop power supply technology, the power supply voltage and output signal are transmitted through a two core cable
- 4-20mA output or digital signal output
- Resolution 1mm
- Not affected by working conditions such as noise, steam, dust, vacuum, etc
- Not affected by changes in medium density, viscosity, and temperature
- The process pressure can reach 4MPa
- The process temperature can reach 500 ℃
Principle
INPUT
The sensor receives the reflected microwave pulse and transmits it to the electronic circuit. The microprocessor processes this signal and identifies the echo generated by the microwave pulse on the surface of the material. The correct recognition of echo signals is completed by intelligent software, with an accuracy of up to millimeter level. The distance D from the surface of the material is proportional to the time travel T of the pulse: D=C × T/2 (where C is the speed of light)
Since the distance E of the empty tank is known, the material level L is: L=E-D
