The short version

  • Each has a real cost: Petasense petasense is now owned by AssetWatch, whose business is monitoring delivered as a managed service, so a buyer wanting self-service software should get the delivery model written into the contract rather than assume it.; Sight Machine onboarding is a data engineering project measured in months per plant, so value arrives long after the contract starts and the internal sponsor needs the patience and budget to survive that gap.
  • They diverge on capability: Petasense covers Vibration Mote, Sight Machine covers Unified plant data model.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Petasense

  • A reliability team wanting continuous vibration data on assets currently covered by a quarterly walkaround routenot Sight Machine
  • A plant with variable frequency drive assets where generic vibration analytics produce too many false alarmsnot Sight Machine
  • Mixing battery sensors on accessible pumps with wired sensors on the handful of assets that would stop productionnot Sight Machine
  • A manufacturer with no in-house vibration analyst that wants the analysis delivered as a service rather than as a dashboardnot Sight Machine

Sight Machine

  • A corporate operations team that cannot compare plant performance because every site defines a stoppage differentlynot Petasense
  • A manufacturer whose historian data is plentiful but has never been modelled into anything a business can querynot Petasense
  • A group standardising manufacturing reporting into a cloud data warehouse alongside finance and supply chain datanot Petasense
  • A quality organisation investigating a defect that appears at several plants with different equipmentnot Petasense

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Petasense

  • Petasense is now owned by AssetWatch, whose business is monitoring delivered as a managed service, so a buyer wanting self-service software should get the delivery model written into the contract rather than assume it.
  • Hardware is required per measurement point and gateways are required per area, so the up-front capital for a plant-wide deployment is substantial and separate from the subscription.
  • Per-asset subscription pricing scales linearly, which makes full coverage of a large population of low-value motors uneconomic compared with route-based monitoring.
  • Nothing is published on sensor cost, subscription rate, gateway requirements or contract length, so a total cost of ownership figure requires a full sales engagement before you can compare it against anything.
  • Battery-powered wireless sensors trade measurement richness for battery life, so the sampling rate and resolution are lower than a wired analyser would give, which limits diagnosis of high-frequency bearing defects on critical machines.

Sight Machine

  • Onboarding is a data engineering project measured in months per plant, so value arrives long after the contract starts and the internal sponsor needs the patience and budget to survive that gap.
  • It assumes the instrumentation already exists, so a plant whose machines produce no usable data gets nothing from a data platform and needs to solve connectivity first with a different class of product.
  • Pricing scales with plants and data volume and is never published, which puts it out of reach for single site manufacturers regardless of how relevant the capability sounds.
  • It is not an MES and does not control or execute anything, so it sits on top of the operational systems and adds a layer to maintain rather than replacing one.
  • Success depends on a central team that owns definitions and enforces them, and in groups where plants retain autonomy the standardisation the platform provides gets quietly ignored at site level.

Questions people ask

Is Petasense or Sight Machine better?
Neither clearly leads. Petasense starts at On request and Sight Machine at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Petasense or Sight Machine?

Does Petasense or Sight Machine run on more platforms?
Petasense runs on Web, Cloud, iOS, Android. Sight Machine runs on Web, API.
What is Petasense best used for?
Petasense is most often used for a reliability team wanting continuous vibration data on assets currently covered by a quarterly walkaround route, a plant with variable frequency drive assets where generic vibration analytics produce too many false alarms, mixing battery sensors on accessible pumps with wired sensors on the handful of assets that would stop production, a manufacturer with no in-house vibration analyst that wants the analysis delivered as a service rather than as a dashboard. Of those, a reliability team wanting continuous vibration data on assets currently covered by a quarterly walkaround route and a plant with variable frequency drive assets where generic vibration analytics produce too many false alarms are not what Sight Machine is typically brought in for.
What can Petasense do that Sight Machine cannot?

Answered from the vendors’ own pages

Petasense: Is Petasense still a separate product?

Yes. It trades under its own name with its own product line, but the owner since January 2024 is AssetWatch.

Sight Machine: Is this an OEE product?

It can produce OEE, but buying it for OEE alone is expensive. The reason to buy it is cross plant data standardisation.

Petasense: Do I have to buy Petasense hardware?

Yes. The platform is built around its own Motes and Transmitters; it is not a bring-your-own-sensor analytics product.

Sight Machine: Does it need a historian?

It reads from historians, control systems and MES. Some source of machine data is a prerequisite.

Petasense: Can I get monitoring as a service?

Yes, through parent AssetWatch, whose model is condition monitoring engineers reviewing your data. Clarify which model your quote covers.

Sight Machine: How long does a plant take to onboard?

Plan in months per plant, depending on how many sources and how inconsistent the existing definitions are.

Petasense: How is it priced?

Per monitored asset on subscription, plus sensors and gateways. Nothing is published.

Sight Machine: Who is the buyer?

A corporate manufacturing, quality or digital function. It is rarely a plant level purchase.
