Product catalog summary
Overview
MTI Instruments provides precision measurement solutions with a focus on capacitance probes that offer stable and precise non-contact measurement with nanometer resolution. They also design custom capacitive probes to meet specific measurement requirements.

Applications
Capacitance probes are used in various applications including microscope focus, lens alignment, part profiling, semiconductor wafer thickness, piezo stage displacement, vibration measurement, and more.

Standard Features
- Temperature Rating: Probes and cables can operate between -130ºC to 200ºC, while connectors are rated from -65ºC to 85ºC.
- Accuracy: ±0.02% FSR or better when calibrated.
- Filter Bandwidth: Standard at 500Hz, with optional bandwidths available.
- Resolution: Varies with bandwidth, calculated as (0.000423 x bandwidth in Hz + 1.2) x 0.00002 x FSR.
- Pressure Rating: Standard at 1400kPa (200 psig).
- Material: Stainless steel construction with no active internal electronics.

Product Specifications
MTI offers a variety of capacitance probes compatible with the Accumeasure family of amplifiers. Specifications include:
- Range extensions are available but may decrease linearity.
- Probes are available in different configurations such as ILR, CTR, ILA, HT, CTA, PCA, and PCR, each with specific range and sensitivity parameters.

Calibration and Fixturing
MTI provides calibration fixtures like the KD-CH-IIID and FS-2 to secure and position probes accurately for calibration and measurement.

Optional Accessories
MTI offers various accessories including standard cables, low noise extension cables, BNC couplers, and probe calibrators.
