LRT-G1620 series

Standard radar level gauge
LRT-G1620 standard radar liquid level gauge is a kind of measurement of liquid level based on the principle of the time difference between the generation and reception of radar waves. It has non-contact, high precision, wide measuring conditions, is not affected by pressure, and can meet most measurement requirements. Suitable for open air, closed liquid level measurement, product belt display, optional explosion-proof, 30 meters range can be set.

Specification
Performance Features
Performance characteristics:
LRT-G1620 standard radar level gauge series sensor is 26G high frequency radar level measuring instrument, measuring distance up to 15 meters. The antenna has been further optimized, and a new, fast microprocessor enables higher rate signal analysis and processing, allowing the meter to be used to measure a variety of highly corrosive liquids.

Application:

Liquid (substance) level measurement in most working conditions

Measuring range: 15, 30 meters

Process connection: thread, flange

Process temperature: -40 ~ 130℃(standard type) / -40 ~ 250℃(high temperature type)

Process pressure: -0.1 ~ 4.0MPa

Accuracy: ±3mm

Protection level: IP67

Frequency range: 26GHz

Power supply: two-wire system (DC24V)/ four-wire system (DC24V/AC220V)

Explosion-proof grade: Exia ⅡC T6 Ga/Exd IIC T6 Gb

Case: Aluminum single cavity/aluminum double cavity/plastic/stainless steel single cavity

Signal output: 4... 20mA/HART(two-wire/four-wire)/RS485 Mod bus

 

Product characteristic:

● Small antenna size, easy to install; Non - contact radar, no wear, no pollution.

Almost free from corrosion and foam; Almost unaffected by changes in water vapour, temperature and pressure in the atmosphere.

● Severe dust environment has little influence on the work of high frequency level meter.

● Shorter wavelength, better reflection on tilted solid surfaces.

Small beam Angle, concentrated energy, enhance the ability of echo and avoid interference at the same time.

● Measurement blind area is smaller, for small pot measurement will also achieve good results.

● High signal-to-noise ratio, even in the case of fluctuation can get better performance.

● High frequency, is a great product for measuring solid and low dielectric constant media.
