DC operated Linear Variable Differential Transformers (LVDTs) have signal conditioning electronics built into the LVDT and require no calibration or special signal conditioning. Units can be powered with uni- or bi-polar DC voltages and have scaled DC voltage, current or digital outputs. Ranges from +/-0.050” to +/-10.000” are available.
Position Sensor - DC-EC Series
Description: The DC–EC AccuSens™ Series incorporates a unique monolithic chip combined with a computer-designed AC LVDT to achieve premium performance. The ratiometric design of the monolithic circuitry compensates for power supply deviations for continuously stable operation. Unaffected by input variations, the transducer provides highly accurate, repeatable measurement. Innovative manufacturing techniques further enhance the AccuSens operation and cost efficiency. Micro-miniature components used in the construction of each unit are selected for maximum stability. Vacuum encapsulation of all elements produces an assembly tolerant to shock, vibration and other forms of physical abuse. Double magnetic shielding protects against stray electrical fields.

The DLS-B is an optical measuring device. You can measure, maintenance-free, distances on natural and reflective surfaces. You determine positions on objects difficult to access or with very high surface temperatures. Just as well you can measure distances in an aggressive environment in an easy and accurate way.
Serial, analog and digital interfaces are standard features for the complete DLS-B product line. This enables you to easily connect the DLS-B to a control system (SPS, IPC or PC)
The DLS-B device runs in a “Stand-alone-mode” and independently executes all programmed functions. Thanks to the flexible range of functions an external display can be connected directly to the DLS-B device via interface RS232 or RS422. Via a digital input, measurements can also be activated from an external button or switch.
For easy configuration of the DLS-B devices, the necessary software is at your disposal

Magnetostriction - A Milestone in Measurement Technology
The heart of MTS sensors is the ferromagnetic measuring element, also known as the waveguide, and a movable position magnet that generates a
direct-axis magnetic field in the waveguide. When a current or interrogation pulse passes through the waveguide, a second magnetic field is created radially around the waveguide. The interaction between the magnetic field in the waveguide and the magnetic field produced by the position magnet generates a strain pulse which travels at a constant ultrasonic speed from its point of generation, the measurement point, to the end of the waveguide where it is transformed into an electric pulse in the sensor element. The resulting signal is processed by the specialized electronics of the Temposonics sensor. With our extensive know-how of ferromagnetic materials, magnetic effects and ultrasonic processes, MTS remains unrivalled in performance standards for non-contacting position measurement of the highest precision.

POSIC presents a new type of inductive position sensor for the measurement of gears, disks and linear bands. The IS2201 sensor consists of a differential microcoil transformer that is integrated on a silicon chip together with the associated electronics, leading to an extremely robust and very compact sensor.
The differential inductive sensor has a high immunity against magnetic and electromagnetic perturbations, does not need a bias-magnet and works with ferromagnetic (iron, nickel) as well as with electrically conducting (aluminum, copper, brass) gears and discs. These features make the microcoil sensor ideally suited for applications where magnetic sensors fail or show reliability problems.
Typical applications are in the motion control domain with magnetic actuators like brushed and brushless motors, voice coil actuators etc. Markets served include industrial, automotive, robotics, medical, instrumentation and office equipment.
The IS2201 sensor comes in the form of a 8.7 x 6.2 mm PCB with two half-holes for alignment/fixation, ready for assembly in e.g. an electric motor or an industrial machine.

The confocal chromatic measurement system, optoNCDT 2401, consists of a controller and a sensor. A fiber optical cable, which can be of almost any length, connects the two components. This system has no moving components and is therefore wear free. It can also be used in ATEX / EX environments. The system consists of a LED based controller a fiber optical cable and one of the sensor heads of the series 2400/2401 or the world first miniature sensors series 2402. This unique measuring principle enables displacements and distances to be measured with high precision and extreme
spatial resolution. Both diffuse and specular surfaces can be measured. With
transparentmaterials a one-sided thickness measurement can be accomplished along with the distancemeasurement. Since the emitter and receiver are arranged in one axis, shadowing is avoided. In contrast to conventional triangulation sensors the optoNCDT 2401 system is able to measure in narrow apertures, small gaps and cavities. The series optoNCDT 2402 is also with radial beam deflection for bore hole inspection available.
