Frequency response, sensitivity, linearity, and immunity: The GT2-100N offers selectable response times from 3 ms to 4,000 ms. This supports dynamic measurement. High sensitivity comes from the 0.1 µm resolution. Linearity depends on the connected sensor head. The unit resists industrial noise through its NPN open collector output. For full environmental tolerance, refer to the sensor head specifications.
Installation Guide
- Mount the GT2-100N on a panel. Use the large display for easy reading.
- Connect a compatible GT2 series sensor head. Ensure the head matches your measurement range.
- Wire the 10 to 30 VDC power supply. Keep ripple below 10 %.
- Connect control inputs for timing, preset, reset, or bank selection.
- For communication, add an optional GT2 series communication unit.
Debugging and Maintenance Convenience
The large display shows measurements clearly. You can set preset and reset values quickly. Bank switching helps manage multiple setups. The unit has no built-in ports. This reduces setup complexity. Regular cleaning of the sensor head is recommended. The amplifier itself needs no routine maintenance.
Compatibility Notes
The GT2-100N works with GT2 series sensor heads. It supports GT2-Pxxx heads with extended response times. For network communication, use optional GT2 communication units. The NPN output suits many PLC and control systems.
