This paper makes a description of the nonmagnetic material (3J_1 alloy) used to make the Probe of inclinometcrs including its chemical composition, mechanical performance and heat-treatment technology of typical 3J_1 alloy parts.
It combines the air bearing gauge head with a square guideway with the microminiature capacitive sensor, ensuring high accuracy and high frequence response It's suitable for ultraprecision contact measurement.
The scheme is very unique in using the special structure of the artillery bore to design m echanical structure and assembly system of gauge head . The special structures ca n guarantee the best orientate and guide of gauge head.
Based on the working principle of non-contact capacitance sensor, influence of the edge effect of gauge head and width of protecting ring are studied, gauge head for measuring blind hole is designed to sight the centers of two adjacent holes.
Based on the capacitance type sensor, the influence of edge effect of gauge head and the width of protecting ring are studied, two thickness-measuring capacitance sensors are introduced to measure differentially the wall thickness between two holes.
The measuring probe is one of the key parts of the coordinate measuring machine(CMM),which is a kind of precise measuring instrument. The precision of the probe decides the measuring repeatability of the CMM directly.
Using the information about the faces and their neighboring relationship, the paper provides a kind of method and tactics of establishing knowledge(ruler) base for probe heads selection and accessibility analysis .
A variation of normal and tangential components of magnetization of a ferromagnet has been considered in the area below a measuring probe.
Dogs were instrumented with indwelling portal vein and carotid artery catheters, a catheter jejunostomy and an electromagnetic flow measuring probe around the portal vein enabling continuous flow recordings.
Methods of measuring probe potential and current are described, and the essential results of such measurements are discussed.
Based on the evanescent field principle, a quartz glass fiber with a polysiloxane cladding is used as in-situ measuring probe.
The measuring probe consists of a heater covered with conductive epoxy and temperature sensor deposited on the probe-tissue interface.
We evaluated the properties of pyramidal probe heads using the FDTD (finite difference time domain) method and obtained simulation results in order to find the best structure and design for new near-field optical probes.
Two replaceable probe heads were available: a circular 2.5-cm coil and a quadratic 5-cm coil, both of which were placed directly on the skin.
Modelling of pretravel for touch trigger probes on indexable probe heads on coordinate measuring machines
This paper presents a pretravel model for touch trigger probes mounted on indexable probe heads, which can rotate and tilt the probe into a number of orientations for coordinate measurements on coordinate measuring machines (CMMs).
This WANTED (water-selective DANTE using gradients) sequence thus allows the observation of interactions with water without the use of special probe heads or filtering of undesired resonances.
