Ultrahigh Precision Gaging Probes
General Purpose Spring Loaded LVDTs
Short Range Economy LVDT

GHSA/GHSAR Series
Spring Loaded AC LVDT

These heavy duty AC operated units use sleeve bearings to provide good repeatability and extended service life in shop floor applications. Three different configurations are available: the GHSA, with an axial connector for close mounting; the GHSAR, with a radial connector for shorter installed length; and the GHSAR-A, an air extend/spring retract version with a radial connector. (more info)
  • Available in standard 0.750"
    [19 mm] diameter
  • Ranges of ±0.05" to ±2"
    [±1.25 mm to ±50 mm]
  • Repeatability of 0.000025"
    [0.60 µm] or better
  • In-line or through-bore design
  • Mating plug for connector included
  • Also available in air extend/spring retract versions (GHSAR-A)

GHSD/GHSDR Series
Spring Loaded DC LVDT

The DC operated GHSD/GHSDR Series utilize built-in electronics that convert a ±15 V DC input into a precalibrated 0 to ±10V DC output. Like the AC version, it is available in seven standard ranges from ±0.020" [±0.51 mm] to ±2.00" [±50 mm] and three different mechanical configurations: GHSD (axial connector); GHSDR (radial connector); and
GHSDR-A, (air extend/spring retract).
(more info)
  • Available in standard 0.750"
    [19 mm] diameter
  • ±15 V DC input, precalibrated 0 to ±10 V DC output
  • Precalibrated ranges of ±0.02" to ±2.00" [±0.51 mm to ±50 mm]
  • Repeatability of 0.000025"
    [0.60 µm] or better
  • Available in in-line, through-bore or air extend/spring retract versions (GHSDR-A)

GHSE/GHSER Series Spring
Loaded Single-Ended DC LVDT

The GHSE/GHSER Series offer all the advantages of our other general purpose spring loaded LVDTs, but are powered by a nominal 24 V DC input and are available in six standard precalibrated ranges from 0.100" [2.5 mm] to 4.00" [100 mm] with an output from 0-10V DC. Axial (GHSE), radial (GHSER), and air extend/spring retract (GHSER-A) versions with sealed connectors are available. (more info)
  • Available in standard 0.750"
    [19 mm] diameter
  • 24 V DC input, precalibrated 0 to 10 V DC output
  • Precalibrated ranges of 0.10" to 4.00" [2.5 mm to 100 mm]
  • Repeatability of 0.000025"
    [0.60 µm] or better
  • Available in in-line, through-bore or air extend/spring retract versions (GHSER-A)

GHSI/GHSIR Series Spring
Loaded Loop Powered LVDT

GHSI/GHSIR Series LVDTs offer all the advantages of our other general purpose spring loaded LVDTs, along with the convenience and simplicity of precalibrated 4-20 mA current loop operation. Units operate as 2-wire loop powered or 3-wire sourcing externally powered. Axial (GHSI), radial (GHSIR), and air extend/spring retract (GHSIR-A) versions with sealed connectors are available. (more info)
  • Available in standard 0.750"
    [19 mm] diameter
  • 4 to 20 mA input/output
  • Precalibrated ranges of 0.10" to 4.00" [2.5 mm to 100 mm]
  • Repeatability of 0.0001"
    [2.50 µm] or better
  • Available in in-line, through-bore or air extend/spring retract versions (GHSIR-A)

BBP/BBT Series
Dimensional Gaging Probes

The probes' exceptional repeatability is due, in part, to the use of a linear ball bearing assembly precisely fitted to a hardened-and-ground, non-rotating probe shaft to minimize radial play and the effects of side loading. One end of the probe shaft is coupled to the core of a friction-free LVDT sensor, which produces an output voltage that is linearly proportional to the probe shaft position. (more info)
  • Ultra-precision linear ball bearing assembly gives repeatability of less than 0.000006" (0.15 μm)
  • Industry-standard .315" (8.0 mm) and .375" (9.5 mm) diameters
  • Ranges from ±0.040” (±0.5 mm) to ±0.200” (±5.0 mm)
  • Exceptionally long life; 200 million cycles
  • Available in low pressure air-extend/spring-retract pneumatic versions

GSA Series Economically Priced
Short Range LVDT

The GSA Series of short range spring loaded position sensors were developed for cost sensitive applications requiring LVDT reliability and performance. (more info)
  • Ranges of ±0.10" to ±0.30"
    [±2.5 mm to ±7.5 mm]
  • ±0.5% maximum linearity error
  • Economical 3/4 inch size
  • 220 °F (105 °C) operating temperature
