Category: Weighing Indicators
Key Benefits
- A/D conversion with 1 in 30000 readability for fine division work
- Anti-vibration software for benches near moving machinery
- Counting function with data retained if power is lost
- LCD and LED display variants under one model family
Problems It Solves
- Readings that will not settle on a shop floor
- Counting data lost when power fails
- Coarse resolution limiting the division a scale can display
Who It Is For
- Platform and floor scale manufacturers
- Plants weighing near vibrating equipment
- Builders needing a fixed value output for simple control
Application Scenarios
- Floor scale on a production floor with vibration
- Counting station where the count must survive a power cut
- Platform scale with one to four load cells
Technical Features
- A/D conversion with readability 1 in 30000
- Anti-vibration software with settable digital filter intensity, range and stable time
- Zero tracking and zero range setup, automatic or manual
- Counting function with unit data save protection on power off
- Optional kg and lb switching, animal scale function and two fixed value TTL outputs

Materials And Construction
- Plastic housing
Customisation Options
- LCD or LED display variant
- Animal scale function on A12 and A12S
- Two fixed value TTL outputs as an option
Use Guide
- Tune digital filter intensity and stable time to the vibration actually present rather than to maximum
- Keep RS232C cable runs within 30 metres
- Use the internal code display to analyse tolerance rather than judging by the weight reading alone
How It Compares
| XK315A1 indicator | The XK315A1 is the simpler general purpose head with a wider standard function list. The A12 focuses on high resolution conversion and vibration rejection. |
|---|---|
| XK3101 control indicator | For real batching control with fieldbus and multiple on-off outputs, the XK3101 is the correct head. The A12 offers two fixed value outputs only. |

Indicators are bought by part number and regretted by function. Decide what the head has to do on site first, then check it can drive your cells.
How To Choose Load Cell Capacity And Accuracy Class
Capacity and accuracy class are the two numbers that decide whether a scale can be built and verified. Here is how to derive both before you commit to a design.
