Given the relationship between capacitance and plate distance, the tilt in one axis changes the distance signal measured by the electronics and this signal serves as the feedback for the tilt. This means that the probe is moved by the picomotor actuator towards the target in the x -direction until the electronics indicate a value of 49 μm.

Trimmer Capacitors

A trimmer capacitor is a type of variable capacitor (a capacitor that can have its capacitance manually adjusted by changing the positioning of the two conductive plates). A trimmer capacitor differs from a regular variable capacitor in that it''s smaller, and its value is set initially during production and is meant to be left there for some time until an …

Evaluating Trimmer Capacitor Choices

The capacitance range and the number of turns to adjust that range determine the amount of control over a capacitance setting. Trimmer capacitors are available in low-cost models with 1 to 2 pF of capacitance and one-half turn to units with tuning ranges to 250 pF and more and multiple turns of adjustment.

Trimmer & Variable Capacitors

Device construction & Distinguishing traits Trimmer and variable capacitors are devices that provide a capacitance which is variable within some range, the difference between the two terms being mostly one of design intent; a "trimmer" capacitor is usually intended to be adjusted only a handful of times over its service life, …

OverviewMechanically controlled capacitanceSpecial forms of mechanically variable capacitorsHistoryElectronically controlled capacitanceTransducersNotesExternal links

A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.
