Anisotropic Magneto Resistive or AMR sensors offer robust non-contact measurement of changes in the magnetic field as seen by the sensor. This effect allows for the creation of sensors that can detect disturbances ranging from extremely weak fields, as found in traffic detection sensors, to strong field sensors that are used in precision encoders.

AC operated Schaevitz™ and MEAS Linear Variable Differential Transformers (LVDT’s) contain no electronics and are therefore the first choice when small size, hostile environments or low cost are required. AC LVDT’s when used in conjunction with Measurement Specialties Signal conditioners (see Instrumentation) offer the maximum amount of flexibility for outputs and scaling. Ranges from +/-0.005” to +/-10.000” are available.

DC operated Schaevitz™ and MEAS 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.

LVDTs with a spring-loaded plunger and bearing assembly (gageheads) that allows for easy installation. The core rod assembly does not need to be attached to the part to be measured making the gagehead an ideal solution for assembly lines and gaging stations. AC, DC and digital output versions are available. Ranges from +/-0.020” to +/-2.000” are available.

The Measurement Specialties line of Angular Position Sensors offers DC RVDTs (Rotary Variable Differential Transformers) and RVITs (Rotary Variable Inductive Transducers) with a measuring range up to ±75 degrees with DC voltage output. Custom Ranges are available.

Our unique RVIT (Rotary Variable Inductive Transducer) designs incorporate our proprietary technology and signal-conditioning on a single printed circuit board. With no brushes or wipers to wear, the non-contact, long-life sensor is reconfigured for each OEM, allowing the best possible cost savings.

These sensors are ideal for measuring displacement in the most demanding industrial, automotive and defense applications.

Measurement Specialties develops innovative custom packaged solutions for rotary sensing applications using magnetic sensing technology. An encoder is a sensing device that translates either linear or rotary motion into a predictable electrical output.

Magnetic encoder technology has shown to be superior to existing optical encoder technology in areas of:

• Temperature range

• Contamination resistance

• Operational life

• Shock and vibration

• Critical assembly operations

• Cost

Main magnetic encoder applications

• Panels (for user inputs)

• Feedback (for OEM—PCB assemblies and packaged encoders)

Common magnetic encoder uses

• Vending machines

• Equipment controls

• Flow meters

• Medical devices

　

　

Measurement Specialties' dual axis tilt sensors, inclinometers, and clinometers use fluid filled capacitance or conductive technology for measuring ranges between ±2° up to ±45° inclination in both the X- and Y-axis. The sensor units are reliable, have a wide spectrum of modern technology with high accuracy and resolution at an affordable price.
