AC/AC LVDT works under pressure and temperature extremes.

Press Release Summary:

Aug 04, 2014 - Rated for pressures to 35,000 psi at continuous temperatures to 450°F, High-Temperature High-Pressure Linear Displacement Transducers (LVDTs) have .30 in. OD body with perforated housing that equalizes internal and external pressure. Fluids must be electrically non-conductive and chemically benign, since holes in housing expose internal coils. Non-linearity is ±0.25%, and temperature coefficient of sensitivity is ±0.01%/°F. Signal conditioners for DC/DC or 4–20 mA operation are available.

New Size for AC-AC LVDT Works Under Extreme Pressures and Temperatures

Press release date: Jul 30, 2014

Trans-Tek offers a new model in its unique line of high-temperature, high-pressure, Linear Displacement Transducers (LVDT). The new model, based on Trans-Tek’s Series 230, has a .30” O.D. body style. Previous models are still available with either 3/8” or 3/4” OD body style. Originally developed for a manufacturer of tools for the down-hole oil drilling industry, other applications include R&D testing and wherever extreme environments with deeper pressures and higher temperatures exist than standard LVDT’s would withstand.

These transducers employ a perforated housing to equalize pressure inside and outside the LVDT. Thus, fluids must be electrically non-conductive and chemically benign, since the holes in the housing expose the coils inside. Many hydraulic oils meet this requirement. High temperature ratings of these transducers are achieved by using special internal materials.

All three of these LVDT’s are rated for pressures to 35,000 psi, at continuous temperatures as high as 450°F. Non-linearity is ±0.25% and temperature coefficient of sensitivity is ±0.01% per Degree/Farenheit. A high sensitivity output offers infinite resolution in a variety of strokes. Trans-Tek high-temp/high-pressure LVDT’s are available with signal conditioners for DC-DC or 4-20 mA operation.

Trans-Tek was formed in 1967 to manufacture a broad line of Linear and Angular Displacement, and Linear Velocity Transducers. The company has grown from a small startup to a multimillion dollar manufacturer . It operates from a 14,000 sq. ft. facility in Ellington, CT, where all of its transducers are manufactured.
