together and connect with transmitter through RF cable.
Picture 3-1 Capacitive sensor and amplifier
1 Function
Capacitance sensor can be used with many kinds of capacitive sensing heads, which can measure the physical
quantities for relative capacitance change (distance, pressure, temperature, thickness, level, etc.) and adjust the
sensitivity or measuring range. When sensing head touch the object under testing, indicator lights flash (red light),
and give collision signal (+ 24V or 0V for optional). Crashing signal occurred when the distance is less than 0.1
mm between head and the object to be measured. Crashing signal output +24V when the red indicator light on the
amplifier box, and signal output 0V without crashing occurs.
2 working principle
The capacitance sensor is to transform the capacitance change of sensing head when working into electrical signal,
to measure the physical quantities under testing (distance, pressure, temperature, thickness, level, etc.) through the
signal amplification, demodulation and filtering processing.
