HG-S measurement sensor
Slim unit body
- Slim robust pencil-type sensor unit
- Bending-resistant cable even when used for moving parts
- Hot-swappable
- Plain bearings with 2-point support structure ensure excellent resistance to lateral loads
- Resistance to lateral load
- 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.
- 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.
- 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).
- Lateral load is generated when the sensor is positioned at an angle or the workpiece becomes tilted.
- Lateral load resistance test: The sensor withstands 100 million sliding operations (reference value).
- The two plain bearings increase the resistance to mechanical stress from the side and ensure the accuracy of measuring results even under lateral load.
* F = Force
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
- Dual display for more flexibility
- All-direction LCD
- Intuitive circle meter
- 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.
- Secondary display line: Displays sensor head measurement and other data.
- 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.
- Higher than maximum value.
- 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.
- High
- Set value
- Low
- Self-trigger level (ST level)
- Delay timer
- 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.

HG-S communication unit
Direct transfer of high-precision measurement values: new communication unit for the HG-S series
The new RS485 communication unit for the HG-S sensor series is used to transfer high-precision measurement values directly, making data traceability easier than before. Communication does not only work for measurement values, but also for parameters, making it easy to manage inspection results and identify causes in the event of a failure.
Installation example
In a network installation, a PLC and a computer can be used to control a number of stations remotely. Each station consists of a master, up to 14 slaves, and the SC-HG1-485 communication unit. The maximum number of stations is limited by the communication protocol selected: 99 stations for MODBUS (RTU/ASCII) and 64 stations for MEWTOCOL-COM.
- Station consisting of a master sensor, up to 14 slave sensors, and the SC-HG1-485 communication unit
- Two protocols available:
- MODBUS (RTU/ASCII) for connection of up to 99 stations
- MEWTOCOL-COM for connection of up to 64 stations - Programmable controller FP7 series
- PC for analysis and cause investigation
- Web server for data logging
