Product catalog summary
Overview
The document provides a comprehensive overview of the Accumeasure series by MTI Instruments, which offers non-contact capacitance position measurement solutions with nanometer accuracy. These systems are designed for various applications, including desktop systems, modular rack systems, and OEM board-level solutions.

Accumeasure 9000
The Accumeasure 9000 is a cost-effective solution for single and dual-channel applications, such as thickness measurements and dual-axis motion stages feedback control. It features a built-in universal AC power supply and summing amplifier, offering high resolution and linearity.

Accumeasure 500
The Accumeasure 500 is a modular rack system that can accommodate up to six measurement channels or summing amplifiers. It is suitable for large multi-channel applications and can be synchronized for multichannel operation. An optional 12 Vdc version is available for in-vehicle testing.

OEM Solutions
MTI offers OEM amplifier solutions, including the Accumeasure MicroCap for high-volume applications and custom boards like the AS-562 and AS-563 for large multi-channel applications.

Probes
Accumeasure probes are available in standard and custom designs, including high-temperature and push/pull configurations. They are designed to maintain a uniform electric field and reduce noise and external influences.

Measurement Principles
The Accumeasure system uses parallel plate capacitor measurement principles. The capacitance between the probe and target surface varies with the distance, and the system converts this capacitance into a proportional output voltage.

Specifications and Accessories
The document includes detailed specifications for the Accumeasure systems, including measurement range, resolution, accuracy, and power requirements. Accessories such as cables, connectors, and calibration fixtures are also described.

Conclusion
The Accumeasure series offers high accuracy, stability, and repeatability for non-contact capacitance measurements, making it suitable for a wide range of industrial applications.

Capacitance Measurement-4

Capacitance Measurement Principles AccumeasureTM System measurement technology is based on the principle of parallel plate capacitor measurement. The electrical capacitance formed between an AccumeasureTM probe and a target surface varies as a function of the distance (gap) between these two surfaces. see Figure 1 Capacitance based measurement probes have long been employed as a means of non-contact measurement of electrically conductive materials. In a typical system, MTII's capacitance probe acts as one of the plates and the grounded target the other plate. MTII's amplifier converts the gap's...
