Wireless Silo Weighing
A company was looking for a cost effective way of displaying the weight of four silos on large LED displays in a control room which was 50 metres from the silos..jpg)
The Problem:
A cost effective solution was needed. Historically this would have involved cables to be run from each measurement point in the silo and then back to the control room which was not only expensive, but involved several days of installation.
The Solution:
The solution was achieved by connecting a radio telemetry T24-SA strain gauge acquisition module to each vessel. The T24-SA can interface to sensors as low as 85 Ohms so were easily able to connect to the four load cells mounted on each silo.
The T24-SA modules were permanently powered and transmitted their weights at a rate of three per second. A T24-SO radio telemetry to serial output converter mounted 50 metres away monitored these transmissions and reformatted the data into a serial output which was fed via RS232 to four addressable large-digit LED displays.
