What's Inside the Electronics Head of a Magnetostrictive Displacement Sensor: Pulse, Echo, Output

What's Inside the Electronics Head of a Magnetostrictive Displacement Sensor: Pulse, Echo, Output

No output or jumps? The magnetostrictive displacement sensor head splits into pulse drive, echo detection, processing, output. Match block to fault.

How to Choose the Position Magnet for a Magnetostrictive Displacement Sensor: Remanence, Gap, Mounting

How to Choose the Position Magnet for a Magnetostrictive Displacement Sensor: Remanence, Gap, Mounting

The ring magnet is not stronger-is-better. For a magnetostrictive displacement sensor, weak remanence loses the echo; match remanence, gap, mount.

Operating vs Storage Temperature for a Magnetostrictive Displacement Sensor: Read the Ratings Right

Operating vs Storage Temperature for a Magnetostrictive Displacement Sensor: Read the Ratings Right

Storage temperature is survival unpowered only. A magnetostrictive displacement sensor is accurate over operating temperature, head narrower than rod.

Two Positions from One Waveguide: Multi-Magnet Sensing on a Magnetostrictive Displacement Sensor

Two Positions from One Waveguide: Multi-Magnet Sensing on a Magnetostrictive Displacement Sensor

Several magnets on one rod: a magnetostrictive displacement sensor reads 2-4 positions in echo order, but Series 19 needs 76 mm minimum spacing.

Matching Response Time and Refresh Rate to the Control Cycle of a Magnetostrictive Displacement Sensor

Matching Response Time and Refresh Rate to the Control Cycle of a Magnetostrictive Displacement Sensor

Refresh rate must beat the control cycle of a magnetostrictive displacement sensor. Wave travel grows with range, so long-stroke units refresh slower.

How to Connect Magnetostrictive Displacement Sensors to a Fieldbus: A Practical CANopen and EtherCAT Guide

How to Connect Magnetostrictive Displacement Sensors to a Fieldbus: A Practical CANopen and EtherCAT Guide

Stuck on CANopen Node-ID and PDO mapping? This fieldbus guide for a magnetostrictive displacement sensor covers Node-ID, PDO not SDO and 120-ohm ends.

Do Magnetostrictive Displacement Sensors Need Warm-Up? Self-Heating and the Real Temperature Effect

Do Magnetostrictive Displacement Sensors Need Warm-Up? Self-Heating and the Real Temperature Effect

Does a magnetostrictive displacement sensor need warm-up? The head self-heats and settles in about 30 min; then steady temperature stops drifting.

Dead Zones at Both Ends: Why a Magnetostrictive Displacement Sensor Must Not Bottom Out

Dead Zones at Both Ends: Why a Magnetostrictive Displacement Sensor Must Not Bottom Out

Every stroke end hides a dead zone on a magnetostrictive displacement sensor. Never guess 30 mm - take Series 16, 17 and 19F blind-zone figures.

Absolute vs. Incremental Position: Why Magnetostrictive Sensors Never Lose Zero on Power Loss

Absolute vs. Incremental Position: Why Magnetostrictive Sensors Never Lose Zero on Power Loss

Power cut? An incremental encoder must re-home; a magnetostrictive displacement sensor need not, because torsion-wave timing holds absolute position.

The Three Accuracy Terms of Magnetostrictive Sensors: Resolution, Repeatability and Non-Linearity

The Three Accuracy Terms of Magnetostrictive Sensors: Resolution, Repeatability and Non-Linearity

Three accuracy terms on a magnetostrictive displacement sensor: smallest step, scatter to a point and full-stroke deviation are not the same number.

Installing Magnetostrictive Displacement Sensors in Practice: Position Magnet, Zero Point, Noise Immunity

Installing Magnetostrictive Displacement Sensors in Practice: Position Magnet, Zero Point, Noise Immunity

Wild readings come from mounting, not failure. On a magnetostrictive displacement sensor, set magnet coaxiality, two-point zero, screened earthing.

Troubleshooting Magnetostrictive Displacement Sensors: Inaccurate Readings, Jumps, No Output

Troubleshooting Magnetostrictive Displacement Sensors: Inaccurate Readings, Jumps, No Output

No output, jumps or offset on a magnetostrictive displacement sensor? Check the 20.4-28.8 V supply and polarity, then magnet coaxiality and zero.
