Series 240 Specs Linear (LVDT) Displacement Transducers

Product catalog summary

Overview: This document outlines the technical specifications and options for Series 290 and Series 240 Linear Variable Differential Transformers (LVDTs) by Transtek Inc., covering both AC and DC models. It details features, specifications, and available options for these precision measurement devices.

Series 290 - General Purpose AC LVDTs:

Options: Offers splashproof protection, longer leads, integral connector replacement, and welded non-lead end for specific models.
Core Extension Rods: Essential for full-range operation, made from nonmagnetic stainless steel. Shorter rods may limit measurement range.

Series 240 - General Purpose DC LVDTs:

Features: Integrated package with precision LVDT, solid state oscillator, and phase-sensitive demodulator. Provides excellent linearity, infinite resolution, and high sensitivity.
Specifications: Ranges from ±0.05” to ±4.0”, non-linearity < 0.5%, stainless steel construction, and 6 to 30 VDC excitation.
Electrical Notes: Proper polarity of excitation is crucial, with a minimum load impedance of 50 KOhms required. Transducers are calibrated at 24 VDC.

Core Options:

Constructed from high permeability iron-nickel alloy with nonmagnetic stainless steel extension rods. Options vary based on core outer diameter and threading requirements.

Series 200 - Short Stroke DC LVDTs:

Features: Designed for short stroke applications with ranges from ±0.05” to 0.20”, non-linearity < 0.5%, and high sensitivity.
Specifications: Operates with 5 to 7 VDC input, offering a full-scale output of ±1.5 to ±2.8 VDC depending on the model.

General Notes: Emphasizes the importance of observing polarity for proper function and provides detailed dimensional drawings for installation guidance.

Additional Overview: The document also covers Series 200 and Series 240 DC LVDTs, designed for precision measurement in various environments, including high-pressure and splashproof conditions.

Series 200 - Short Stroke DC LVDTs:

Features: Precision measurement with ranges from ±0.05” to 0.20”, non-linearity less than 0.5%, stainless steel construction, high sensitivity.
Electrical Specifications: Operates with DC voltages, input voltage range of 5-7 VDC, and output voltage of ±1.5 to ±2.8 VDC depending on the model.
Options: Includes splashproof protection, modified extension rod lengths, cable termination options, and offset/scaled output voltage.

Series 240 - General Purpose DC LVDTs:

Features: Suitable for high-pressure environments up to 5,000 PSI, vented housing to prevent pressure differentials, and rapid pressure change tolerance.
Mechanical Specifications: Various stroke lengths available from 0.050” to 3.00”.
Options: Includes splashproof enhancements, modified extension rod lengths, cable termination with extended temperature range, and integral connector termination.

Core Options:

Model numbers ending with an underscore have multiple core options, with standard units ending in 0 indicating a core assembly.
Options include smaller core assemblies and threaded cores for connection to moving objects.

Sales Options:

Various options are available for both Series 200 and 240, including splashproofing, cable termination, and connector types.
For detailed information on specific options, contacting the factory is recommended.

Series 240 Specs Linear (LVDT) Displacement Transducers-3

The high pressure version of the Series 240 is suitable foroperation in nonconductive and noncorrosive fluids or gasses at pressures up to 5,000 P.S.I. The vented housing eliminates pressure differentials between the environment and the transducers interior, allowing rapid and extreme pressure changes without damage or degradation in performance.
