Resources
Guides and white papers: Understand the measurement before you specify it
Technical guidance for engineers evaluating measurement technologies, comparing approaches and working through the practical considerations that affect a system’s performance.
From measurement principles and technology comparisons to integration guidance, these resources are designed to help you make an informed decision before a product is selected.
How to use them
For the decision before the specification
Some engineering decisions are not about choosing between two product numbers. They are about understanding which measurement principle, technology or system architecture is appropriate in the first place.
These guides and white papers address those earlier questions, giving you the technical context to assess the options before narrowing down to a specific instrument.
Explore how different measurement technologies work and the factors that determine where each approach is appropriate.
Understand the practical differences between competing measurement methods, including their strengths, limitations and application considerations.
How-to guides address common engineering tasks and integration requirements, helping you work through the practical detail of putting measurement into a system.
Use the information to assess the approach against your own application before moving into product selection and specification.
Technical subjects
Technical subjects, practical decisions
The collection covers subjects including oil condition monitoring, level measurement, blackwater sensing and ignition technology, alongside wider guidance on measurement approaches and integration.
The content is deliberately not tied to a single product. Its purpose is to help you understand the engineering decision behind the specification.

Understand the principle
How does an ultrasonic wind sensor work?
Sound pulses timed between fixed transducers, and why the principle needs no moving parts and no field calibration.
Read the answerHow capacitive level sensing works
What changes in the sensing region as liquid rises, and how that change becomes a level output.
Read the answerHow inductive position sensing works
Generate, respond, compare. Why the comparison across a coil series gives absolute position rather than relative.
Read the answerSide by side
Compare approaches
Ultrasonic anemometer vs cup anemometer
What you gain and what you give up when the moving parts come out of a wind measurement.
Read the answerCapacitive vs float level sensors
Where a float still wins, and where a sensor with no moving parts is the only thing that survives the duty.
Read the answerInductive vs Hall effect position sensors
Both are non-contact. One needs a magnet and drifts with temperature. Four differences that decide the choice.
Read the answerOptical rain gauge vs tipping bucket
Why a mechanism that has to be cleaned and levelled is a maintenance decision as much as a measurement one.
Read the answerGet the specification right
Specify and prove the measurement
How accurate does a wind sensor need to be?
Accuracy is half the question. Repeatability, long-term stability and the reference speed matter as much.
Read the answerWhat does full-range accuracy mean?
Accuracy stated across the full operating range rather than at a single reference speed, and what that changes in a specification.
Read the answerHow often should a weather station be calibrated?
Setting an interval from the duty and the consequence of drift, rather than from a default on a spreadsheet.

Long-form guides
Marine sensing: knowledge and FAQs
The full marine picture in one place: wind, weather, level and machinery condition at sea, and what salt, motion and class approval add to each.
Read the answerWhat causes bearing failure in gearboxes?
Overload, misalignment, contamination and heat, the signature each leaves in the oil, and how early it can be caught.
