Level Transmitter/Level Switch <Powder/Liquid>
80GHz
RADAR LEVEL TRANSMITTER

 

80GHz Radar Level Transmitter is a radio-wave level meter that measures storage levels in tanks and silos without contact in harsh environments such as dust, steam, and high temperatures.

It is used for inventory management and control of tanks and silos, contributing to automation and labor saving of equipment.

Advantages

  1. Easy adjustment and excellent maintainability for workers.
     
  2. Measurement in a narrow area, long distance (120m) measurement, and measurement of objects with low relative permittivity
     
  3. When any adjustment or technical support from our engineer is requested, remote adjustment can reduce costs.

Features of 80GHz Radar Level Transmitter

The main features of the 80GHz Radar Level Transmitter are as follows.

Easily confirmed
by mobile

Easily confirmed by mobile or PC by bluetooth connection.

No wiring required for adjustment.

Can be operated from safe location even in difficult-to-reach sites.

Adhesion alarm
[Patented]

The adhesion alarm and inspection date are notified by making the beating signal of 4-20mA output, which avoids unstable measurement.

Easily angle adjustment
after maintenance
[Patented]

Angle/Dirension sensor system
After taking out the sensor for maintenance, it is easy to restore the sensor.

Operating principle

In the FM-CW method, the sensor transmits a high frequency radar signal while modulating the frequency at a constant cycle.

When it is reflected and received by the target,  the frequency deviation from the transmitted signal is converted into round-trip time and measured as distance.

How to use?

1.Determine
the mounting
position

Choose a position where no obstacles enter the measurement area of ​​the transmitter, and where the object to be measured does not enter the dead zone of the transmitter.

If you have any concerns about the mounting position, please contact us.

2. Mounting

Adjust the angle of the transmitter so that the transmission direction of the transmitter is as perpendicular as possible to the measurement surface. Angle adjustment is not required if the measurement surface is a flat liquid surface. In addition, it is convenient for maintenance if you make a note of the installation angle after confirming it with the dedicated application.

3. Wiring

Power supply and analog output can be performed with two wires because of the two-wire transmission method. Please connect with our signal conditioner or a current loop supplier procured in commercial market. Measurement starts when the power is turned on.
 

4. Adjustment

By connecting the transmitter to the device via Bluetooth using an app for PC or smartphone, you can easily set 0% and 100%, check the angle.

*For details, please refer to the instruction manual.

 


Local converter for
80GHz Radar Level Transmitter

Signal Conditioner is a converter compatible with 2-wire transmission type sensors and also supports HART communication. It also has a display function, so you can monitor the measured value of the transmitter from a remote location. In addition, it is equipped with analog output and alarm contact output, making it a versatile device.

Maintenance

Notification of adhesion warning and inspection
date [Patented]

When the materials are built up on the transmitting surface, the current output signal (4 to 20mA DC) beats as notification. In addition, this beat signal can be output  as per the inspection date you set up in advance. This function prevents malfunctions and enables stable measurement.

360deg. air-purge
mechanism against
material adhesion

360° slit for purge contacting with the lens surface prevents adhesion to the lens surface

Easy adjustment
even after cleaning
[Patented]

Equipped with angle detection function.

Easy to restore when the transmitter is removed from the equipment during inspection or renewal.
