HG-S Measurement Sensor

Slim unit body

  1. Slim & robust pencil-type sensor unit
  2. Bending-resistant cable even when used for moving parts
  3. Hot-swappable
  4. Plain bearings with 2-point support structure ensure excellent resistance to lateral loads
  5. Resistance to lateral load
  6. High accuracy: The high-precision sensor head has a resolution of 0.1µm and an indication accuracy of max. 1µm for the full range and max. 0.5µm for the narrow range. The high-resolution CMOS sensors measure the amount of movement by reading the glass scales that have different slit patterns at different read positions. This provides accurate measurements even in high-speed measuring operations. It also eliminates mechanical zero position runs when the system has been switched on.
  7. Resistance to upward thrust impact: Even when a sudden upward thrust impact occurs, the resulting load is applied only to the lower section of the sensor unit. The spindle stopper minimizes the impact on the glass scales.
  8. Tip deviation amount of max. 35µm

Hot-swappable

 

The sensor head can be changed safely without turning off the controller. This reduces the man-hours required for changing the line setup when different workpieces need to be processed.

Excellent workmanship

The two plain bearings are accurately aligned with the center of the spindle during their installation to the top and bottom sections of the body to ensure smooth sliding.

Resistance to lateral load

 

The two plain bearings are accurately aligned with the center of the spindle during their installation to the top and bottom sections of the body to ensure smooth sliding. The sensor can withstand more than 100 million sliding operations under application of lateral load (reference value).

  1. Lateral load is generated when the sensor is positioned at an angle or the workpiece becomes tilted.
  2. Lateral load resistance test: The sensor withstands 100 million sliding operations (reference value).
  3. The two plain bearings increase the resistance to mechanical stress from the side and ensure the accuracy of measuring results even under lateral load.

Resistance to upward thrust impact thanks to spindle stopper

 

Even when a sudden upward thrust impact occurs, the resulting load is applied only to the lower section of the sensor unit because a spindle stopper minimizes the impact on the glass scales.

 

Versatile and easy-to-use controller

 

  1. Dual display for more flexibility
  2. All-direction LCD
  3. Intuitive circle meter
  4. Copy function from master to slave units

 

High-speed response of 3ms in combination with any sensor head

Useful maintenance mode for the production floor.

The following data are stored and can be used for analysis on the spot:

  • Abnormal sensor head upward thrust value
  • Number of sensor head upward thrusts
  • Cumulative total number of sliding operations

Alarm for upward thrust

An alarm can be set to notify the user of an upward thrust (stroke) that exceeds the set level. This allows you to conduct a preventive maintenance before the sensor head generates a malfunction.

Easy-to-understand 2-line digital display

 

The 2-line digital display simultaneously shows head measurement (measured value) and judgment value (calculated value). The high-contrast LCD provides sharp and clear indications and offers a wide viewing angle.

  1. Secondary display line: Displays sensor head measurement and other data.
  2. Main display line: displays judgment value.

 

Intuitive circle meter

 

Values within the maximum and minimum limits are indicated in green. Values outside the valid range are indicated in orange. This allows users to check the margin to the limits at a glance.

  1. Higher than maximum value.
  2. Lower than minimum value

 

Copy function

During configuration of the master unit, the copy function symbol lights up for setting items that can be copied to slave units. This significantly reduces the man-hours required for configuration and maintenance.

Easy tolerance setting – simple 1-point teaching

 

Align with master workpiece and press ENTER for easy tolerance setting.

1. Master workpiece
2. Press once!
3. Tolerance setting completed!

4. Tolerance on positive side (HIGH set value)
5. Reference value
6. Tolerance on negative side (LOW set value)

No need for trigger input thanks to self-trigger function

 

The measurement process does not need to be triggered externally. It starts automatically when either the fluctuation of measurement values has stabilized or with a specified time delay after the self-trigger level (ST level) has been reached

1. Static width setting
As soon the measurement curve is stable within the specified range, the measured value will be sent to the analog output.

2. Delay timer setting
When the measurement value has reached the ST level and the specified delay time has elapsed, the measured value will be sent to the analog output.

❶ High
❷ Set value
❸ Low
❹ Self-trigger level (ST level)
❺ Delay timer
❻ Static width

 

Serial connection of up to 15 slave units

 

One master unit can be connected in series with up to 15 slave units in any order. This allows easy multi-point calculations. End plates (optional) must be mounted on both sides of the controller after the connection of slave units.
