Linear displacement sensor

non-contactcapacitiveamplified

High resolution, low cost sensors to measure gap and displacement in industries such as semiconductor, electronics, R&D applications and many more. For grounded targets MTI offers standard capacitance probes. For ungrounded or poorly grounded targets MTI offers push/pull dual sensor probes. Both types of probes are available in stainless steel construction or flat and flexible polyimide construction. Polyimide flat probes are perfect for gap applications or confined spaces. Standard capacitive sensors require the target to be electrically grounded (for position, gap and vibration measurement applications). Current flows from the probe face to the target and back to the amplifier to complete the circuit. The capacitance between probe and target is proportional to the distance and converted to a 0 – 10V output from the amplifier. The measurement of electrically grounded targets can be, however, affected by changes in the electrical conductivity or ground path of the target.
