This remote 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 D cells and is configured using free T24 Toolkit software which runs on a computer connected to a T24 base station. External powering is also possible with a suitable dc power supply. Using good quality alkaline batteries, a 700ohm loadcell, a 100ms sample time at 3 readings a second with 24 hours a day operation the battery life is approximately 18 days. The Toolkit software will calculate typical battery life for a given set of conditions.
Loadcell connections are via field terminals. Full details are given in the manual.
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.
Alternative calibrations are possible; please consult our engineering department to discuss your requirements.
Complies with EMC directive, 2004/108/ECThe Radio Equipment and Telecommunications Terminal Equipment (R&TTE) Directive, 1999/5/EC. RoHS compliant.
Cased battery powered loadcell data acquisition unit.
T24 manual is available for download. The T24 system can be calibrated in a number of different ways depending upon the application. Please consult our engineering department for help with your requirements.
