The Last Few Centimetres: How Cushioning Changes the Reading, and How to Read the Cushion
2026-10-19 · Technical Insights

The Last Few Centimetres: How Cushioning Changes the Reading, and How to Read the Cushion

The last few centimetres of a hydraulic cylinder stroke are not travelled at constant speed. Once the cushion collar enters the bore the return flow is throttled and the piston decelerates sharply. That deceleration is written into the position reading: the curve end flattens and the in-position moment moves later. Read the other way, the same segment is a diagnostic window — smooth deceleration is normal, a step or oscillation means the cushion needs attention.

Two Feedback Loops, Not One: Why Spool Position and Cylinder Position Are Measured Separately

Two Feedback Loops, Not One: Why Spool Position and Cylinder Position Are Measured Separately

A servo valve circuit carries two position loops that are easy to confuse. The spool is held by the valve internal feedback and sets response speed. The cylinder needs an externally mounted magnetostrictive displacement sensor and sets where the load finally stops. With only the inner loop, flow offsets from load asymmetry and oil temperature cannot be corrected. This piece separates the two jobs, lists the four checks when selecting the outer unit, and covers the three mistakes most often made on site.

Cold and Warm Readings Differ: Thermal Expansion or Magnetostrictive Displacement Sensor Drift

Cold and Warm Readings Differ: Thermal Expansion or Magnetostrictive Displacement Sensor Drift

One reading in the morning, another at noon, a third in the afternoon — and range, zero and wiring all check out. When a cold machine and a warm machine read differently at the same mechanical position, there are two sources: the structure itself is expanding as it heats, and the magnetostrictive displacement sensor drifts with temperature. The two differ by an order of magnitude, and confusing them sends you adjusting in the wrong direction. Three field tests separate them.

Why One Divider Valve Cannot Keep Two Cylinders Together: Four Errors Open Loop Never Corrects
2026-09-29 · Technical Insights

Why One Divider Valve Cannot Keep Two Cylinders Together: Four Errors Open Loop Never Corrects

Two cylinders push the same beam. The command is identical, the valves are identical, and the beam still runs crooked. The problem is not tuning. A divider valve synchronises by splitting flow, and with no position value anywhere in the circuit four errors stay uncorrected: the flow split itself, flow shifting under asymmetric load, oil compressibility, and internal leakage plus oil temperature drift. The position difference keeps accumulating along the stroke until something else stops it.

Mechanical, Divider Valve or Servo Closed Loop: Choosing Between Three Ways to Sync Cylinders
2026-09-29 · Technical Insights

Mechanical, Divider Valve or Servo Closed Loop: Choosing Between Three Ways to Sync Cylinders

Every multi-cylinder sync scheme reduces to one of three: enforce it with structure, split the flow, or close a loop on position. All three work, in different territory. Mechanical sync is easiest when spans are short and strokes are small, a divider valve is enough when the load is symmetric and the tolerance loose, and servo closed loop becomes unavoidable once the load is asymmetric or the tolerance reaches a few parts in a thousand. A three-step test decides which applies.

Ten Injection Presses, One Jittering Ejector Sensor: A Thin Mounting Plate Acting as a Tuning Fork

Ten Injection Presses, One Jittering Ejector Sensor: A Thin Mounting Plate Acting as a Tuning Fork

We ran all ten injection moulding machines on site up to maximum ejector speed. Only one reading jittered; the other nine stayed steady. The cause was not the sensor: on that smaller machine the mounting plate was not rigid enough and too thin, so at speed the plate resonated like a tuning fork and fed high-frequency vibration down the cantilever into the sensor core. A replacement sensor would not have helped. Fitting an anti-vibration base cleaned the waveform immediately. A second, separate fault turned up in the same batch: installation over-travel, with the slider passing the black mark on the housing at the bottom of the stroke on several machines.
