Intro
A company was looking for a cost-effective way of displaying the weight of four silos on large LED displays. These were located in a control room which was 50 metres from the silos.
The Challenge
Significantly, they needed an economic solution. Historically, this configuration would have required workers to run cables from each measurement point in the silo to the control room. This was not only expensive, but also required several days of installation. It would also have left cables in the ground which could impact future works.
The Solution
The solution was achieved by connecting a radio telemetry T24-ACM-SA strain gauge acquisition module to each vessel. In general, the T24-ACM-SA can interface to sensors as low as 85 Ohms. So, we were easily able to connect to the four load cells mounted on each silo.
The T24-ACM-SA modules were permanently powered and transmitted their weights at a rate of three per second. The T24-SO, mounted 50 metres away, monitored these transmissions. This reformatted the data into a serial output which was fed via RS232. RS232 is a telecommunications standard to allow point to point transmission of data from one piece of equipment to another. The data was transmitted to four addressable large-digit LED displays.
