Accumeasure Capacitance Sensors

Technology-driven measurement solutions for high-resolution gap applications.

The Accumeasure product line features capacitive sensor products for high-resolution gap and displacement measurements that require a high level of stable and repeatable accuracy. A capacitive sensing system consists of a probe and amplifier. Capacitive measurements can be performed in a multitude of environments using non-contact passive capacitance probes that are not affected by magnetic fields, temperature, humidity, nuclear radiation, and pressure. This is largely due to the nature of the rugged and passive capacitance probes.

Extremely high-precision and high linearity amplifiers make these systems ideal for critical measurements in X-Y stages, rotating spindles, shaft position, armature gap, disk position, and piezoelectric positioning applications. MTI engineering guarantees a highly stable, accurate, and low-noise amplifier design with an attention to fast response time.

Thousands of MTI’s products are used globally in the semiconductor, automotive, aviation, electronics, and medical industries. As the leader in capacitance technology with decades of experience, MTI stands behind the quality and performance of the most demanding user environments.
