This series of radar level meter adopted 80G high frequency radar sensor, the maximum measurement range can reach up to 120 meters. Antenna is optimized further processing, the new fast microprocessors have higher speed and efficiency can be done signal analysis, the instrumentation can be used for reactor, solid silo and very complex measurement environment.
Radar level transmitter antenna microwave pulse is narrow, the downward transmission antenna. Microwave exposure to the medium surface is reflected back again by the antenna system receives, sends the signal to the electronic circuit automatically converted into level signals (because the microwave ropagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost instantaneous).
The Characteristics of 80G Radar Level Meter
1.Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
2.Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.
3.Serious dust environment on the high level meter work has little effect.
4.A shorter wavelength, the reflection of solid surface inclination is better.
5.Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
6.The measuring range is smaller, for a measurement will yield good results.
7.High signal-to-noise ratio, the level fluctuation state can obtain better performance.
8.High frequency, measurement of solid and low dielectric constant of the best choice.
Explosion Proof Connection
The intrinsic safety version sensors (Exia IIc T6) use Alu-die casting housing and filling.Silicone rubber sealants internal structure aimed to prevent sparks resulted from circuit failure from leaking out. It is applicable for the continuous level measurement of flammable medium under Exia IIc T6.
A safety barrier FBS-2 must be used together with the intrinsic safety instrument. It is an associated device to this product for the power supply of this product. The main specification is intrinsic safety: Exia IIC, voltage of power supply: 24V DC ± 5%, short-circuit current:135mA, operating current: 4-20mA.
All cables must be shielded. The max length is 500m for the cable from the barrier to the sensor. Stray capacitor ≤ 0.1 μ F/Km, stray inductance 1mH/Km. Instrument must be connected to the ground potential. Any unapproved associated device is not allowed to be used.
Application of Radar Level Transmitter
Radar level gauge is a high-precision non-contact measuring instrument commonly used for liquid level measurement of various liquid media such as water, industrial wastewater, hydrochloric acid, nitric acid, sulfuric acid, acid-base solution, cement slurry, lime slurry, and various food slurry. It is widely used in fields such as building materials, chemical engineering, petroleum, water conservancy, environmental protection, food, medicine, etc.
