Linear Hall Sensor
The output of a hall effect sensor is a voltage which changes in proportion to the shaft extension. A constant voltage is required across the supply and ground wires of the sensor. The sensor consists of a Hall Effect element, and a shaft which houses a magnet. When the position of the sensor changes relative to the shaft, the change in magnetic field in the sensor results in a change in output voltage.

Radio Telemetry
Procter & Chester Measurements Ltd
Radio Telemetry: A transmission of data from a remote source via a radio to a receiving station for recording and analysis. Inductance: A contactless method of supplying power to (in this case) a strain gauge bridge. The signal is then transmitted back to the electronics. Slip Ring: Consists of a conductive band mounted on a shaft and is insulated from it. The wheatstone bridge is connected to the bands (usually four off). Fixed brushes or contacts make contact on to the bands to transfer power to the bridge and signal back to the static instrumentation.

Vibration Diagnostics System
VDS
The Vibration Diagnostic System (VDS) is a vibration data management system designed specifically for the machinery Predictive Maintenance (PdM) community. It harnesses the graphic display capabilities of Crystal Instruments EDM Software for the work of machinery vibration analysts. It allows the user to quickly get to the data for a machine of interest and displays that data in the familiar Tri-axial or Single Axis view. Users can quickly compare other data from the same machine, quickly navigate back into the historical data of the machine, and quickly compare the data to that of other machines in the database. The software supports the construction of Average (a.k.a. baseline) data for a class of machines and allows easy comparison to that data as well. A full suite of cursors designed specifically for PdM analysis is provided for inuitive user interaction with the data.In addition to great graphics, an extensible machine modeling system was developed specifically for vibration analysis. VDS allows users to model machines based on the elements of the machine that can contribute to the vibration energy of the whole. Model bearings, rotors such as motor bars, couplings such as flexible and fluid couplings, account for slip in fluid couplings, model gears and pulley systems, and model turbines by accounting for each stage. The system is wide open, users can create new elements to use within a system. Users that may not want to do all that are provided with a comprehensive library of machine components such as AC and Induction Motors, Couplings, Gears, Pulleys, Pumps, and other components. Single and double gear shafts allows users to model many kinds of gear boxes with an unlimited number of stages. This ability alone lets users model their machines to view and use to keep track of vibration pickup locations, record the forcing frequencies of each part of the system, and attach attributes such as manufacturer and other part information.

Tachometers/Torque Meters
Tachometers measure rotational or linear speed and come in two styles: contact and non-contact. Contact models come with various rubber/plastic adapters for interfacing the instrument’s shaft with the surface of the spinning or moving surface under test. Non-contact models come with reflective tape that is placed on the surface to become the target of the instrument’s low-power laser.

DLx
Linear Variable Differential Transformer (LVDT) and Rotary Variable Differential Transformer (RVDT) are transformer-type voltage/current transducers that convert a linear/rotary movement of a core/shaft to a multi-wire differential AC electrical signal. Both deliver signals linearly proportional to the position of a shaft (magnetic induction core). An LVDT/RVDT simulator is used to convert digital positional commands to corresponding AC signals.

Non-Contacting Single-turn
A rotary position sensor translates angular positions to an electrical signal. Rotary position sensors are designed for applications that typically require frequent adjustment. Shaftless designs allow for a different engagement mechanisms, such as a customized shaft, a motor control, a human interface adjustment or a mechanical arm position locator. Rotary position sensors can be used in applications where a user needs to control a variable output such as a frequency, speed or volume control. Typical applications include test and measurement equipment, consumer electronics, small engines, robotics, and medical equipment. The Bourns® Model AMS22S Series uses Hall Effect magnetic technology to sense rotary position.
