|MS LBB series
An ultra-precision series using linear ball bearings and supporting spring-extend and air-extend.
The Linear Ball Bearing (LBB) series of dimensional gaging probes is engineered for highly precise and repeatable measurements in quality control and metrology applications.
Linear ball bearings within the gaging probe minimize radial play and friction for ultra-precise measurement. Bearing assemblies utilize two circumferential rows of miniature balls held in position by a retainer. The balls ride on a non-rotating plunger hardened to Rockwell 65, hardchrome plated and precision ground for optimal repeatability and resistance to brinnelling. The contact end of the plunger has a removable tungsten carbide ball tip, with an AGD standard 4-48 UNF-2A threading. (See page 100 of the Schaevitz catalogue for replacement and alternate tips.)
Plunger and bearings are enclosed in a cylindrical housing, hand-honed and fit to the ball bearing assembly. Precision fitting provides for exceptional gage head repeatability. With the bearings and housing essentially matched in hardness, the plungers can better tolerate side loads for a longer unit life.
|MS GCA & GCD Series
Description: Stainless steel construction enables the GCA/GCD Series gauge head to perform in environments containing moisture, dirt and other contaminants. Electronic components are hermetically sealed for added protection against hostile conditions. These are heavy duty, long stroke units with ranges up to ±2.0" (50mm). Maximum spring force is typically 8 oz (226.8g), dependent upon probe position.
The working end or probe has a removable chrome plated, hardened tool steel tip threaded to the probe with a 4-48 UNF-2A threading. Schaevitz® replacement and alternate contact tips are available (see page 100 Schaevitz Catalogue). Tips are also interchangeable with AGD dial indicator tips. Internal construction prevents the core and shaft from rotating as they move longitudinally. Units terminating into connectors allow for easy cable replacement if damage should occur. Installation and adjustment are facilitated by external threading; locknuts are provided.
GCA/GCD Series gauge heads are available in AC and DC versions. AC-operated units utilize external signal conditioning (see LVDT Instrumentation section of this catalog); DC-operated units incorporate the core, LVDT and all necessary electronics in one housing. Use of monolithic, surface mount circuitry eliminates most of the volume, weight and cost of conventional AC excitation, amplification and demodulation equipment.

Descriptions: The Measurement Specialties PCA-116 family of gauge heads was developed for less demanding applications where a balance between cost and performance is paramount.
PCA-116 gauge heads incorporate a standardized LVDT with repeatability better than 0.0001" (0.0025 mm) and linearity within 0.5% of full range output. The probe shaft is externally sprung and is carried on low friction nylon sleeve bearings. The probe to bearing clearances are designed to minimize problems should contaminants get into the bore. Units are supplied with replaceable hardened steel tips that thread to the probe with a 4-48 UNF-2 thread.
Replacement or alternate tips are available. Any 4-48 AGD dial indicator contact tip can also be used.
