Manufacturing loadcells since 1972
T24-ACMi/SA Miniature Loadcell Telemetry Data Acquisition Unit
This miniature loadcell data acquisition unit provides high performance wireless measurement of loadcell outputs. Providing direct mV/V input and 5V bridge excitation for up to 4 load cells. Low power modes allow the module to power down between transmissions or to power off completely and can be controlled by other T24 products such as the handheld displays or a base station.
The data acquisition unit uses a pair of standard alkaline AA cells and is configured using free T24 Toolkit software which runs on a computer connected to a T24 base station. Using good quality alkaline batteries, a 700ohm loadcell, a 100ms sample time at 3 readings a second with 3 hours a day operation the battery life is approximately 32 days. The Toolkit software will calculate typical battery life for a given set of conditions.
Loadcell connections are via a standard Binder 723 series cable mounted socket. The pin connections are the same as the TR150 and TR200 loadmeters.
If the unit is supplied with a loadcell it will normally be calibrated to read the loadcell output in the same force units as the loadcell calibration. A traceable system certificate will be supplied for this calibration. The loadcell and this unit are the only parts of the telemetry system that require calibration. We can also supply the unit scaled to 2mV/V for use with F256 set-up wheel installations. Please see the T24-SYSC data-sheet for more information.
Alternative calibrations are possible; please consult our engineering department to discuss your requirements.
The T24 system can be used with any of our loadcells. Details of our loadcell families can be found in the Loadcell Specifier Guide. Details of our loadcell families can be found in the Product Guide.
