Industrial Position Sensing Technologies Engineered for Real-World Performance

At VARIOHM, we do not view position sensing as a standalone component selection.
We engineer position as part of a complete measurement architecture.

In many applications, engineers begin by asking:

What is the required stroke?
What resolution is needed?
What output signal is preferred?

These are important questions — but they are not sufficient.

In real industrial systems, position sensing operates under:

• Continuous vibration

• Thermal cycling

• Mechanical misalignment

• Electrical noise

• Dynamic motion

• Long operational life expectations

A position sensor must be selected and integrated with these realities in mind.

Position Is Not a Static Value – It Is System Behavior

Datasheet accuracy represents laboratory conditions.
Field stability represents engineering.

At VARIOHM, our position sensing solutions are designed to ensure:

• Long-term repeatability

• Thermal stability

• Resistance to vibration and shock

• Mechanical robustness

• EMC resilience

Because position feedback is rarely passive — it is part of control logic, safety systems, and dynamic regulation.

Engineering for Stability – Not Just Resolution

In industrial systems, performance is influenced by:

• Mounting geometry

• Mechanical tolerances

• Environmental sealing

• Signal conditioning

• Cable routing and shielding

• Calibration strategy

A high-resolution sensor can underperform if system architecture is neglected.

At VARIOHM, we support engineers in evaluating the full sensing chain — not just the sensor head.

CASE STUDY – Improving Position Stability in a Mobile Industrial Application

The Challenge

A mobile hydraulic control system required continuous linear position feedback under:

• Constant vibration

• Wide temperature fluctuations

• Outdoor environmental exposure

An initial potentiometric solution met laboratory specifications but showed degradation in field conditions.

Root Cause Analysis

• Mechanical vibration accelerated internal wear

• Temperature variation introduced measurable drift

• Inadequate shielding exposed the signal to interference

The sensor selection did not fully account for environmental stress.

Engineering Solution

• Transition to a contactless inductive linear sensor

• Improved mechanical isolation

• Shielded cable integration

• Defined calibration protocol

Result

• Stable signal under vibration

• Extended operational life

• Reduced maintenance intervention

This case reinforces a core principle:
Technology selection must align with system architecture.

Frequently Asked Questions – Industrial Position Sensors

What is the difference between potentiometric and inductive linear position sensors?

Potentiometric sensors rely on physical contact and are suitable for general industrial applications.
Inductive sensors are contactless, offering superior durability, vibration resistance, and long service life.

How does temperature affect position sensor accuracy?

Thermal expansion and electronic variation can introduce drift.
Sensors must be selected based on real operating temperature ranges, not nominal conditions.

Are inductive sensors always superior?

Not universally.
Technology selection depends on application constraints, mechanical architecture, cost targets, and environmental stress.

Why do position sensors fail in industrial systems?

Failures are typically due to:

• Mechanical misalignment

• Vibration

• Poor installation

• Inadequate environmental protection

• Lack of calibration planning
