Trans-Tek, Inc. products

The Series 280 AC LVDTs are designed and manufactured to provide an accurate, yet economical, means of measuring linear displacement. The transducers are available in working ranges of 0.1 to 2.0 inches. Maximum non-linearity is specified as ± 0.4% of full scale.

The Series 210-220 AC LVDTs offer precision linear displacement measurements for applications with strokes from 0.5 to 60 inches. The transducers have been designed with an extremely low temperature coefficient, and non-linearity of less than ±0.25% F.S. Variable pitch secondary windings are incorporated into the design with computer controlled winding machines to minimize package length to stroke ratio, and assure a uniform product.

The Series 240 DC-DC LVDTs are an integrated package consisting of a precision linear variable differential transformer, a solid state oscillator, and a phase-sensitive demodulator. The transducer is designed for excellent linearity, infinite resolution, and high sensitivity. Input and output circuits are electrically isolated from each other and from the coil assembly housing, making them usable directly in floating or ground return systems. DC indicators, recorders, and control systems can usually be driven directly by the large DC output. The core, when displaced axially within the coil assembly, produces a voltage change in the output directly proportional to the displacement.
