Detecting the amount of material remaining in a hopper

Detecting the amount of material remaining in a hopper in a simple and stable manner

You wish to detect the amount of various types of material in a large hopper in a simple and stable manner.

[Issue] Configuration of threshold values and insufficient detection distance

• Threshold settings are calculated using the potentiometer and exhibit variability depending on which worker configures them.
• The sensing distance is insufficient.
• The sensor is installed at a height, making it difficult to change the settings.
• The settings must be changed for each type of material.

[Solution] Use an HG-F1 Series Laser Distance Sensor to measure the amount of material remaining in the hopper.

Use a compact and long-range HG-F1 Series Laser Distance Sensor to measure the height of the material remaining in the hopper.

Distance setting　

The sensor can accommodate color variations, eliminating the need to change settings, even when dealing with numerous types of material.

Broad-range measurement　　　

A single model can accommodate various hopper sizes.

Digital display　　

The sensor features a digital display of measured values, and it can be configured by anyone.

External input function　　

Using the sensor’s external input function, threshold values can be set from an easily accessible touch panel.
