Certifiable Design
- Single or dual module 475 installations are components of an NTEP approved scale and can be upgraded to NTEP compliance by adding weigh modules in the future (minimum three modules required for NTEP compliance).
- Certificate of conformance, number 92-196, was issued under the National Type Evaluation Program (NTEP) of the National Conference of Weights and Measures. The certificate is for capacities of up to 3,480 STPH with belt loading of 14.5 to 145 lb./ft. at belt speeds of 100 to 800 FPM.
Weight Sensing Device
- Direct Mounted Weigh Suspension (no moving parts)
- Precision Alignment in both Horizontal and Vertical Planes (critical to accurate weighing)
- Single Strain Gauge Load Cell
Speed Sensing Device
- Magnetic or Optical Speed Sensor
- Bracket Supplied for Tail (Non-Driven) Pulley Mounting for True Speed Pick-up
Connection Box
- Connections for both Load Cell and Speed Sensor Wires
- NEMA 4X Enclosure
- Connects up to (4) Weigh Modules
- Pulse Cut-Off Switch for measuring belt length
Calibration
- Electronic
- Material Test
- Test Chain (optional)
- Test Weight (optional)
Accuracy
- ± 0.5% to 0.25% or better when installed and maintained according to MERRICK instructions
