The 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
Custom printing: dockets can be customised for the application. The built in RS232/RS485 port can be configured for printing.
R400 Series K491 firmware is approved for trade use in Australia
"The instrument may be provided with an automatic tilt sensor/compensation device that automatically compensates for out of level conditions up to ±10° in longitudinal or transverse directions. The tilt sensor/compensation device consists of a Rinstrum model M4904 tilt sensor and model M4211 tilt compensation module. The model M4904 tilt sensor uses a HL Planar model NS 10/PL2-S dual axis compensation level sensor."
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.
