Features

They perform with a ±0.3 % F.S. linearity for stainless steel and iron

Because they perform with a ±0.3 % F.S.
linearity, they can be used for sensing stainless steel and iron enabling precise measurements not affected by the work’s material. Specifications corresponding to each material (stainless steel, iron, aluminum) has already been inputted in the controller enabling the easy selection of the setting that is the most suitable for the particular material used.

±0.3 % F.S. linearity for stainless steel and iron

We’ve realized a 25 μs (40,000 times/sec.) ultra high sampling speed

With a 25 μs ultra high sampling speed, the GP-X series will not miss even high speed work displacements.

These devices boast a 0.07 % F.S./°C temperature characteristics

By combining the sensor head with the controller, we have achieved 0.07 % F.S./℃. Highly resistant to ambient temperature changes enabling stable microdisplacement measurements.

They possess a 0.02 % F.S. resolution for highly accurate measurement

With high resolution, 0.02 % F.S. (Note), they can perform high-accuracy measurements of microdisplacements.
In particular, the sensor head GP-X3SE for 0.8 mm 0.049 in sensing can differentiate ultra microdisplacement of 0.32 μm 0.013 mil (Average number of samples: 64).

Note:
GP-XC3SE and GP-XC5SE
Resolution: 0.04 % F.S.

IP67G sensor head variation

6 types of sensor heads from the ultra compact ø3.8 mm ø0.150 in cylindrical type to the long range sensing type ø22 mm ø0.866 in are available.
All sensor heads are oil-proof as per IP67G enabling safe, stable performance.
* Please check the resistivity of the sensor against the cutting oil you are using beforehand.

The 5-digit, dual, 2-color digital display offers great visibility

If the measurement results fall within the setting range (GO), they will appear on the lower digital display in green.
If they are out of range (HI, LO), they will be displayed in the upper digital display in orange. The display position and color change allows for accurate visibility even for momentary changes.

Digital input display enabling easy setting

Its dual digital display enables numerical setting while verifying setting items for each mode. Even in sensing mode, it enables the verification of the main settings.

The RS-232C communication connector is standard equipment

Capable of various controls such as saving measurement data to PC and the controller's inputted settings and loading stored memory.

The RS-232C communication connector is standard equipment

Enables sensors data comparisons and calculations

It is possible to calculate addition and subtraction of measured data between two inter-connected controllers, as well as to perform 3-value judgment output according to the calculation results. Digital panel controllers are not required because the calculation function is incorporated.

Datalink between sensors is possible

The controller communication unit GP-XCOM (optional) can be linked to up to 8 controllers and load each controller settings and measurement data to a PC via just one RS-232C cable.

OPTIONS

An intelligent monitor (GP-XAiM) optimal for collecting and analyzing measurement data is also available

An intelligent monitor capable of setting each measurement conditions and monitoring waveform display. It can easily perform waveform monitoring, which could until now only be done by the oscilloscope, as well as loading and saving of settings for each condition and function onto a PC.
(Exclusive RC-232C cable is attached.)

BCD output unit GP-XBCD (Optional)

・20 kHz high-speed data output
The measurement data can be processed quickly in the PLC. (Sampling rate: 20 kHz)

BCD output unit GP-XBCD (Optional)

* When using the BCD output unit GP-XBCD, the analog voltage output of a controller becomes invalid.

・4 types of measurement modes available
Measurement modes compatible to the most widely used applications are available. Because of this, inputting setting values can be done with ease. Please select the most appropriate mode to suit your specific application.

・Mutual interference prevention function
Interference of sensor heads can be prevented by shifting the oscillation timing while connecting controllers of maximum 8 units with the interference prevention output line. Precise measurement can be achieved even in cases where many sensor heads are used in a narrow area.

・Removable type terminal block
It is equipped with a removable type European terminal block very convenient during assembly, when dividing the equipment into segments or when performing maintenance. It also features an reverse insertion prevention construction.

・4 types of selectable memory functions
The setting data can be processed in 4 types of memory when measuring. This function enables either the changing of the workpiece, the sensing of multiple products or sensing after product changeover to be done smoothly.
