Product DescriptionThe K491 is a general purpose indicator that uses an accessory module to connect to a 2 axis tilt sensor that provides tilt compensation. The K491 is ideal for specialist truck OEM's requiring electronics for accurate load weighing solutions where the load may be on an angle. Both the ABS R420-K491 and stainless steel R423-K491 are ideal for panel mounting in a truck cab, featuring a large display and programmable function keys. The application is for a truck to have accurate weight readings that can compensate for uneven surfaces where a weight reading might be taken.
Simple calibration: Zero/Span calibration (at 0 angle) and tilt calibration to generate the four tilt parameters that are used to correct the reading.
Accessories: The K491 requires a tilt module and tilt sensor.
- Tilt Module (M4211)
- Rinstrum tilt sensor (M4) suitable for +/- 10 degree
- The tilt sensor must be correctly mounted given the axes that are providing data
- The K491 is compatible with a selection of the other sensors up to +/-15 degrees
1. Zero Calibration (at 0 angle)
- Performed on level surface
- Tilt sensor is automatically set to 0
- Calibrates out any inaccuracies
2. Span Calibration (at 0 angle)
3. Tilt Calibration - this generates four tilt parameters that are used to correct the reading.
..now that\\\'s smart weighing.
