Belt Scales · Sensors & Calibration · Zone 05
A scale is only as accurate as its speed signal, its weigh-class idlers and its last calibration. These are the components and services that hold measurement to its commissioning baseline.
01 / The range
The sensors & calibration range.
Accuracy is quoted as achievable; NRCS accreditation is pending per the catalogue, and final specification is confirmed by Tru-Trac engineering.
Sensors
Roller Speed Sensor
- Brushless system built into the wing roller for accurate belt-speed measurement.
- Weatherproof, fully enclosed design with no exposed parts.
- Reinforced idler-roll shaft for durability; simplified replacement.
- Optional external wheel-to-belt speed sensor.
Stepper Motor Speed Sensor V3
- Gravity-fed speed-sensor wheel that runs on the return belt.
- Protection cover guards the sensing device against material spillage.
- 100 pulses per revolution.
- Two-wire connection to the integrator or junction box.
Weigh-class hardware
Weigh Class Frame & Idlers
- Precise approach and retreat idlers for accurate weight measurement.
- Expertly machined and balanced for exceptional weighing accuracy.
- Manufactured entirely in-house.
Calibration equipment
AccuCal Roller Calibration Chain
- Replicates material-loading dynamics for accurate, repeatable calibration.
- Compensates for belt-tension fluctuations to reduce calibration error.
- Automated carousel and control panel for safe, efficient calibration.
- Compatible with various belt-scale models.
Belt scale services (OEM)
Preventive maintenance
- Full system inspection, repairs, and final calibration and certification, documented.
Scale calibration
- Certified weights, calibration chains or material reference, with a calibration certificate.
Diagnosis and repair
- Root-cause diagnosis, transparent repair, closing with calibration and certification.
Certification
- Calibration and official sealing toward legal-for-trade requirements (NRCS accreditation pending).
Installation
- Precise mechanical installation, which directly drives repeatability and accuracy.
Weighing services and weight studies
- Tailored to specific operational needs.
The accuracy holds because the calibration and service hold.
As the OEM, Tru-Trac services its own scales — the service that holds the accuracy.
