KD-2446 is a non-contact high-precision proximity measuring system
KD-2446 has outstanding precision: static resolution to 12 microinches. This low-cost, easy-to-use system makes precision static and dynamic measurements of metal targets.
KD-2446 system operates on a traditional Colpitts oscillator circuit where the sensor acts as the resonating coil for the oscillator. The proximity of the target to the sensor face pulls the oscillator, changing its frequency and amplitude of modulation, and controlling a variable gain oscillator section within the electronic circuit.
Applications
The KD-2446 may be used in a variety of applications using target materials such as ferrous steel, stainless steel or aluminum. Applications include displacement, vibration, sorting and event capture.
With its excellent sensitivity to small targets and high-speed switching, the KD-2446 is ideal for RPM sensing in harsh environments. The opto-isolated switched output makes the KD-2446 ideal for interfacing to PLC inputs, counters, timers or alarm circuits.
