Image processing unit and Image inspection equipment
PC-10J
Position controller capable of linearly controlling the object parameters such as position and width.
Overview
- This position controller permits the non-contact loop control, edge position control and width measurement in combination with a JB-series line scan camera.
- It measures the pixel count of image sensor that corresponds to the shadow of the object to be measured and outputs the measured results with analog current or analog voltage.
- It also output the 12-bit digital output. (11-bit in case of TL-2048SJ/HJ ) (Optional)
Features
- It provides two analog output systems, the current output system and the voltage output system.
- Equipped with a meter to monitor the output current.
- There are three measurement modes.
Mode A to output the width value between No.1 pixel and the first rising edge of video signal.
Mode B to output the width value between the first falling edge of video signal and the pixel of largest bit.
Mode C to output the width value between the first falling edge and the first rising edge of video signal. - Equipped with the dust cancel function.
- Equipped with the alignment display function to easily collimate light axises of the light source and the camera.
- Equipped with the calibration function to easily check the analog output.
- It can output the digital output. (Optional)
Resolving power
The relationship between bit number and analogue output is as follows.
| Bit number (Camera) | Min.analog value | Max.analog value | Resolution | Values per bit |
|---|---|---|---|---|
| 2048 | I = 4.00mA V = 0.00V |
I = 19.99mA V = 9.99V |
1/2048 | 0.0078mA/bit 0.0049V/bit |
| 5000 *1 | I =4.00mA V = 0.00V |
I = 20.00mA V = 10.00V |
1/4096 | 0.0039mA/bit 0.0024V/bit |
*1. When connecting 5000 bit camera, the measuring area is automatically set and the measuring is made within the range of a maximum of 4096 pixels out of 5000 pixels.
