GH-750-D/E/I Series LVDT DC Spring Loaded Position Sensor

Posted on by admin

The GH-750-D/E/I Series of Spring-Loaded DC LVDT Position Sensors from Harold G. Schaevitz Industries offer robust, linear displacement sensing for industrial gauging, and research environments. Designed with a rugged stainless steel housing, and integrated electronics, these sensors provide long-term durability and accurate position feedback across a wide range of applications.

The built-in spring-loaded shaft ensures consistent contact with the target surface, making the GH-750 series ideal for gauging, surface tracking, and dimensional measurements. Whether for factory automation, material testing, or mobile machinery, these sensors deliver high-resolution, repeatable measurements in harsh conditions.

Key Features

  • DC-Operated LVDT Sensor with integrated electronics (no external signal conditioner required)

  • Spring-loaded probe ensures consistent measurement contact

  • Heavy-duty 0.750″ (19 mm) diameter stainless steel housing

  • Available in multiple output types: Voltage (D/E) or 4-20 mA current loop (I series)

  • Stroke lengths from ±0.050 to ±2.00 inches (±1.3 mm to ±50 mm)

  • Sealed to IP68 for full environmental protection

  • Non-linearity better than ±0.25% of full scale

  • Made in the USA with industrial-grade materials

Built for Precision in Demanding Environments

The GH-750-D/E/I series is specifically designed for applications where accuracy, durability, and ease of integration are paramount. These spring-loaded sensors incorporate a precision return spring to maintain constant surface contact, and internal sleeve bearings that guide the probe shaft with minimal friction or play.

Each unit is hermetically sealed and resistant to dust, water, shock, and vibration, ensuring years of trouble-free operation in even the most aggressive operating environments.

Output Options

The GH-750 series includes multiple output variants to meet your system’s requirements:

  • GH-750-D: ±10 VDC output

  • GH-750-E: 0-10 VDC output

  • GH-750-I: 4-20 mA current loop output

All versions operate with standard DC input voltages and offer stable, low-noise output for direct connection to control systems or data acquisition equipment.

Applications

Industrial Gauging Systems

  • Dimensional inspection and in-process precision thickness measurement

  • Roll stand and caliper positioning

  • Contact-type scanning of manufactured components

Factory Automation

  • Closed-loop control in automated machinery

  • Position verification and sorting

  • Real-time process monitoring

R&D and Test Laboratories

  • Materials and component testing setups

  • Displacement and deflection tracking

  • Life cycle and fatigue testing

Rugged Design and Environmental Sealing

The GH-750-D/E/I’s stainless steel housing and sealed construction (rated to IP68) protect the sensor from the environment. These features make it suitable for submersion, outdoor exposure, or environments where dust, fluids, and debris are common.

The epoxy-potted electronics provide additional resistance to shock, vibration, and thermal cycling, ensuring the sensor performs consistently in the toughest conditions.

Easy Integration

These sensors are plug-and-play compatible with most industrial systems:

  • Built-in electronics eliminate the need for external signal conditioners

  • Standard output formats ensure compatibility with PLCs, controllers, and DAQ modules

  • Simplified mounting with a smooth cylindrical body and threaded front nose

  • Field-proven reliability for reduced maintenance and long service life

Why Choose the GH-750-D/E/I Series?

  • Reliable, spring-loaded contact design

  • Fully integrated signal conditioning simplifies installation

  • Wide selection of stroke ranges and output formats

  • Suitable for continuous industrial use in harsh environments

  • Backed by U.S.-based manufacturing and support

Conclusion

The GH-750-D/E/I Series DC Spring-Loaded LVDT Position Sensors provide an ideal solution for demanding linear measurement applications requiring high precision, ruggedness, and ease of integration. Whether you’re outfitting a quality control station, automating a production process, or monitoring motion in harsh field conditions, this sensor series delivers the performance and reliability needed to succeed.
