RDP DCTH Family
The RDP DCTH family extends over three applications fields.
  • Captive Core guided version
  • Unguided version
  • <.li>Spring return version

The high cycle life, Stainless Steel casing,a choice of Voltage and 4-20mA output and a range of product options and accessories make the DCTH one of the worlds most popular LVDT's.

RDP DCTH500C LVDT with captive guided core and extension rod, range ±12.5mm, 4-20mA output.

MS DC-SE Series
Single ended, low current supply and output interfaces easily to PLC and controllers

The Measurement Specialties (MS) DC-SE Series LVDTs operate on a single-ended DC power supply, and provide either a 0 to +5VDC or +1 to +6VDC output signal (wiring dependent) over their full range of displacement. The extremely linear and low noise output makes the DS-SE Series the perfect choice for interfacing to unipolar inputs of analog-to-digital converters, PLC’s, and various data collection systems.
The DC-SE is internally regulated, thus providing immunity to line ripple and allowing operation from unregulated power sources of between 8.5 and 28VDC. The very low typical 6mA current draw is ideal for remote or battery powered applications. The highly stable oscillator provides excellent temperature performance throughout the operating temperature range, while synchronous demodulation insures superb noise rejection.
The built-in EMI/ESD protection and the shielded cable permit operation in noisy industrial environments, with double magnetic shielding providing the utmost protection from stray fields.
Like in most MS LVDTs, the DC-SE windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a two-component epoxy. This provides excellent protection against hostile environments such as high humidity, vibration and shock.
Available in a variety of stroke ranges from 0.1 to 6 inches, the DC-EC Series can be configured with a number of standard options including metric threaded core, guided core and small diameter/low mass core.
Captive core option: The DC-EC features an optional captive core design (available for most models) that greatly simplifies installation. The core rod and bearing assembly includes a Bronze bearing on the front end for self-alignment, while a PTFE sleeve allows low-friction travel through the stainless steel boreliner (spool tube). The core rod and the bearing assembly are both field serviceable.

Features:
  • Unipolar DC operation
  • Low power consumption
  • Shock and vibration tolerant
  • Capative core option (available on select models)
  • AISI 400 Series stainless steel housing
  • CE compliant
  • Calibration certificate supplied with each unit

MS DC-EC Series
Innovative chip technology gives MS DC-EC series a performance edge

The Measurement Specialites (MS) DC-EC Series DC operated LVDTs combine a computer-designed AC LVDT with custom integral signal conditioning to achieve premium performance. Operating on a nominal ±15VDC supply, the DC-EC Series delivers an extremely linear, low noise, yet high frequency response ±10VDC output.
Innovative design and manufacturing techniques further enhance the DC-EC performance and cost efficiency. The micro-miniature components employed were meticulously selected for maximum stability and thermal performance. Vacuum encapsulation of all elements affords excellent shock and vibration tolerance, while double magnetic shielding provides the utmost protection from stray fields.
Like in most MS LVDTs, the DC-EC windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, and the coil assembly is potted inside its housing with a two-component epoxy. This provides excellent protection against hostile environments such as high humidity, vibration and shock.
Available in a 9 stroke ranges from ±1.27mm (±0.05") to ±254mm; (±10"), the DC-EC Series can be configured with a number of standard options including metric threaded core, guided core and small diameter/low mass core.
Captive core option:
The DC-EC features an optional captive core design (available for most models) that greatly simplifies installation. The core rod and bearing assembly includes a Bronze bearing on the front end for self-alignment, while a PTFE sleeve allows low-friction travel through the stainless steel boreliner (spool tube). The core rod and the bearing assembly are both field serviceable.

MS HCD Series
Designed for harsh enviroments
The Measurement Specialties (MS) HCD series LVDTs includes 9 models from ±1.25mm to ±250mm.
An hermetically sealed, DC operated LVDT the HCD Series are a perfect choice for high performance measurements in environments containing moisture, dirt, and fluid contaminants. Operating on a nominal ±15VDC supply, these heavy-duty LVDTs deliver an extremely linear, low noise, yet high frequency response ±10VDC output.
Qualified at pressures up to 1000 psi (70 bars) and suitable for numerous high pressure applications. They are terminated with a glass-sealed, MS type terminal connector. The connector prohibits the core from passing completely through the coil assembly. HCD units have double magnetic shielding that makes them insensitive to external magnetic influences.
