LVDT Products for Automation Applications

Below are LVDT products that are typically used in Automation Applications.

Spring-Loaded LVDTs are best suited, since the core and coil are assembled into a spring-loaded assembly. This makes the mechanical setup of the sensor into automated machinery less complicated and more cost effective.

When space is tight or the automated machinery configuration does not allow for Spring-loaded LVDTs the free core LVDT is to be considered. The hermetically sealed units are one of the more popular configurations used because of their construction and and connector configuration.

GHSA 750 Spring-Loaded AC-LVDT Position Sensors
The Macro Sensors GHSA 750 Series of 3/4 inch diameter Spring-Loaded AC-LVDTs are designed for a wide range of position measurement and dimensional gaging applications. These rugged hermetically sealed sensors are constructed entirely of stainless steel and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68. Electrical termination is through a sealed axial connector; the mating connector plug is supplied with a unit.

GHSAR 750 Spring-Loaded AC-LVDT Position Sensors
The Macro Sensors GHSAR 750 Series of 3/4 inch diameter Spring-Loaded AC-LVDTs are designed for a wide range of position measurement and dimensional gaging applications. These rugged hermetically sealed sensors are constructed entirely of stainless steel and intended for general industrial use. The coil windings are sealed against hostile environments to IEC standard IP-68. Electrical termination is through a radially mounted sealed connector, which results in a much reduced installed length. The mating connector plug is supplied with a unit. The through-bore design allows for air purging of the sensor’s bearings to remove potential contaminants. [read more]
GSA 750 Spring-Loaded AC-LVDT Position Sensors
The GSA 750 Series of short range Spring-Loaded LVDT position sensors were developed for cost sensitive applications requiring LVDT reliability and performance. Available in ranges of ±0.10 inches to ±0.30 inches, these sensors offer the excellent measurement capabilities of an LVDT at very economical prices. This makes GSA 750 series LVDTs especially attractive for student projects, low over-head machine and fabrication shops, and R & D laboratories on a limited budget. [read more]

GHSIR 750  Spring-Loaded DC-LVDT Position Sensors
The Macro Sensors BBP family of 8 mm diameter pencil-type gaging probes offers ultra-precise measurement of dimensions in a wide variety of Q.C., SPC, and industrial metrology applications. They utilize 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. This results in the probes' exceptional repeatability of 0.000006 inch (0.15 µm). [read more]
