Quality Assurance & Virtual Sensors

Know the quality parameter before the laboratory does

Estimate values that are normally only available from a laboratory test using process signals you already measure, so quality drift is visible continuously rather than hours later.

Operational Challenge

Quality decisions wait on results that arrive too late

Critical quality parameters are often confirmed only by laboratory analysis, hours after the product was made. In between, teams either hold product or accept risk, and a drift that began early in a run is recognized only once it has affected a whole batch.

  • Quality confirmed hours after production
  • Product held pending results that usually pass
  • Manual sampling too infrequent to catch drift
Business impact

Shorten the distance between production and quality insight

Use continuous estimates between laboratory tests to act sooner and hold less product.

Detect quality drift earlier

See a parameter moving away from target during the run instead of after the result arrives.

Reduce product on hold

Give teams a continuous indication between tests, so less product waits for confirmation that it was fine.

Focus testing where it matters

Direct sampling to where the estimate suggests attention is needed, rather than relying on a fixed interval alone.

Quality estimated from signals you already have

MontBlancAI relates process conditions to measured quality outcomes, then uses that relationship to provide a continuous estimate between tests.

Virtual Sensors

Continuous estimates of parameters such as viscosity, moisture or concentration, derived from existing process measurements.

Specification Monitoring

Continuous comparison against specification, with deviations surfaced while the run is still in progress.

Laboratory Comparison

Estimates checked against actual laboratory results over time, so accuracy is validated and stays visible.

Beyond Interval Sampling

See what continuous estimation changes

Move from periodic confirmation to a continuous view of where quality is heading.

Without MontBlancAI
Corrections happen after quality is already affected
Process drift develops between quality checks
Quality is measured only at selected points
Quality issues surface after lab results arrive
With MontBlancAI
Corrections can happen before quality is lost
Quality drift is detected as it develops
Quality is tracked throughout the process
Quality properties are estimated continuously

Common questions about virtual sensors

What a virtual sensor is, how it is validated, and where it does and does not replace laboratory testing.

What is a virtual sensor?

A model that estimates a quality value from process signals that are already measured, for a parameter that would otherwise only be known from a laboratory test.

Can this replace laboratory testing?

No. It is not a replacement for laboratory or regulatory testing. It provides a continuous estimate between tests, which helps teams react sooner and reduce how much product is held pending results.

How is a virtual sensor validated?

By comparing its estimates against actual laboratory results over a representative period, and by continuing to check that agreement as process conditions change.
