Michael Cradit, Technical Services Manager at BinMaster, talks to AZoSensors about Low-frequency Non-contact Level Sensors.
BinMaster have recently released a non-contact level sensor – BinMaster RL. How is this sensor an innovative transition from your current level sensor products?
The RL uses VLF (Very Low Frequency) in the acoustic range to detect targets in dusty environments. Other level indicators use higher frequencies which gives them two disadvantages: 1. Single point detection 2. Loss of signal when there is a high density of dust.
How does the RL design manage challenging level sensor measurement applications?
It is designed to use the physical burst generated by the emitting sound wave to clean the inside of the horn assembly. The RL also uses a wider beam angle so there are redundant signals for the RL to pick up on.
What were the main market requirements that inspired the design and development of this new product?
Not all applications call for the accurate volume accuracy that the 3D Level Scanner provides; sometimes simple level information provided in real time will suffice. We decided that it was time to create a device that will give a reliable level and still use our patented technology.

How does the RL perform in dust?
The RL performs flawlessly in dust just like its “big brother” the 3D Level Scanner.
What data is recorded using this sensor and how is this interpreted for the end-user?
Information provided by the RL includes: Minimum and Maximum Level and per cent full values. The RL uses both RS-485 communication and a 4-20mA analogue signal to relay information to a PC, PLC, DCS and more. The 3D Vision software is also a wonderful tool allowing the user to view all of the RLs on one screen.
What materials are commonly measured using the RL?
The RL will work great with any material that has a bulk density of 12 lbs. /ft^3 or more.
Tough-to-measure materials such as wood chips pose a great challenge with this type of technology. How is RL designed to provide accurate measurements from such samples?
It will penetrate dust but not the material due to the range of frequencies it uses.
Are there any maintenance requirements and installation processes involved in the up-keep of this technology?
Since there are no moving parts on this instrument it is pretty much maintenance-free. Just set the instrument and allow it to perform.
What would you say are the key features of RL?
One of the best things about the RL is its user-friendly interface that allows you to do all configurations from the display. Of course the minimal maintenance and accuracy in tough environments are nice as well.
How do you plan on developing this technology to increase its demand across a range of applications?
With our highly trained technicians and engineers we will continue to test it in a variety of applications and make advancement to the patented algorithm.
