Description

Radar Level Meter

Product overview
This series of radar level meter adopted 26G high frequency radar sensor, the maximum measurement range can reach up to 60 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.

Features

Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.
Serious dust environment on the high level meter work has little effect.
A shorter wavelength, the reflection of solid surface inclination is better.
Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
The measuring range is smaller, for a measurement will yield good results.
High signal-to-noise ratio, the level fluctuation state can obtain better performance.
High frequency, measurement of solid and low dielectric constant of the best choice.

The instrument cannot be installed in the arched or domed roof intermediate. In addition to produce indirect echo is also affected
by the echoes. Multiple echo can be larger than the real value of signal echo, because through the top can concentrate multiple
echo. So cannot be installed in a central location.

Electrical Connection

The power supply voltage:

(4~20)mA/HART (Two wire system) The power supply and the output current signal sharing a two core shield cable. The supply voltage range see technical data. For intrinsically safe type must be a safety barrier between the power supply and the instrument.

(4~20)mA/HART(Four wire system) Separate power supply and the current signal, respectively using a two-core shielded cable. The supply voltage range see technical data.

RS485 / Modbus Power supply and Modbus signal line separated respectively using a two-core shielded cable, the power supply voltage range see technical data.
