Industrial heritage and engineering milestones of Trans-Tek Incorporated

For more than fifty years, American enterprise Trans-Tek Incorporated has focused upon engineering and manufacturing precision position and linear velocity transducers.

Based within Connecticut, the production facility manufactures advanced sensing assemblies built around linear variable differential transformer technology to support demanding industrial manufacturing applications.

The comprehensive Trans-Tek transducer portfolio encompasses AC and DC linear position units, spring-loaded gaging probes, capacitive angular transmitters, and self-generating velocity sensors.

Comprehensive manufacturing quality monitoring spanning coil winding and core machining guarantees long-term zero-point stability and minimal thermal drift under rugged plant operating conditions.

Operating principles and construction of precision LVDT transducers

A Trans-Tek linear variable differential transformer consists of a cylindrical stainless steel body enclosing a central primary excitation coil and two symmetrical secondary windings.

A high-permeability ferromagnetic nickel-iron core travels smoothly through the central bore without wiping mechanical friction against internal coil insulation layers.

As the core shifts away from its null center position, the differential magnetic coupling induces an unbalanced secondary AC voltage proportional to linear motion.

Because the core does not contact internal bore walls, the sensing transducer provides infinite theoretical mechanical life across continuous automated manufacturing machinery.

Application engineering of Series 100 LVT linear velocity transducers

Trans-Tek Series 100 linear velocity transducers operate through electromagnetic induction without requiring external electrical excitation power supplies.

An alnico permanent magnet core moves axially inside an internally shielded wire coil, generating a clean DC voltage output directly proportional to the instantaneous velocity of the monitored mechanical stroke.

This self-generating design avoids electronic signal delay and provides instantaneous dynamic response to rapid acceleration and deceleration cycles.

Series 100 transducers serve extensively in monitoring velocity across hydraulic ram cylinders, mechanical presses, shock absorber evaluation rigs, and structural vibration monitoring platforms.

Non-contact capacitive sensing technology of Series 600 ADT angular units

To measure rotational displacement on rotating shafts without potentiometer wear, Trans-Tek developed Series 600 angular displacement transducers using a differential capacitance measurement principle.

The assembly incorporates fixed stator plates and a non-contact rotor, eliminating friction wear and electrical noise common to sliding resistive contacts.

An internal electronics circuit module transforms capacitive imbalance into a proportional DC analog output voltage characterized by high signal-to-noise performance.

Specialized compact Series 605 and 607 configurations measuring only 9.5 mm in outer diameter facilitate angular positioning in miniature rotary valves and industrial motion control mechanisms.

Dimensional verification and profiling with spring-loaded gaging LVDTs

In industrial parts inspection and automated sorting systems, Trans-Tek Series 350 gaging transducers provide dependable dimensional measurements.

An internal return spring maintains constant contact force against moving workpieces through a hardened wear-resistant contact tip, eliminating the need for rigid mechanical coupling between core and target.

A precision linear ball bearing assembly guides the probe shaft with minimal mechanical play and high measurement repeatability over millions of operational cycles.

Gaging transducers are supplied in DC-DC configurations for direct automation hookup and AC-AC versions engineered for humid metalworking environments.

System integration with industrial automation controllers and conditioning modules

To connect AC-AC inductive displacement transducers with modern programmable logic controllers, Trans-Tek provides Series 1000 oscillator-demodulator signal conditioners.

These modular units supply clean sinusoidal excitation to primary sensor windings while performing synchronous phase demodulation to eliminate plant noise.

Working alongside regulated dual-output DC power supplies, Trans-Tek peripheral modules provide reliable electrical isolation between sensitive sensing lines and factory power drives.

Standard aluminum alloy mounting clamps and positioning brackets allow fast alignment within mechanical machinery without distorting the outer tubular sensor body.
