Position Sensors

With its broad offering of Shaevitz^TM, Encoder Devices, HL Planartechnik and MEAS position sensors, Measurement Specialties is the world’s largest manufacturer of industrial Linear Displacement Sensors and Rotary Displacement Sensors. The combination of materials and manufacturing techniques used for our Linear Variable Differential Transformer sensors (AC LVDTs and DC LVDTs), Rotary Variable Differential Transformer sensors (AC RVDTs and DC RVDTs), inclinometers, clinometers, tilt sensors and liquid level transducers results in extremely rugged transducers which are capable of functioning during and after severe shock loads and vibration. Magnetic encoders offer breakthrough technology for accurate rotary position sensing in harsh weather or difficult industrial conditions

Magneto Resistive Sensors

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.

Gageheads

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. Linear Inductive Sensors

 

 

Our unique LVIT (Linear 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. The device is ideal for measuring displacement in the most demanding industrial, automotive and defense applications. Ranges from +-.005” to +-4.000” are available. Custom Ranges are available.

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
