The short version

  • Each has a real cost: Samotics sAM4 only sees what reaches the motor electrically, so it covers the driven train and misses un-driven equipment, structures, process conditions and anything downstream of a mechanical decoupling.; 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: Samotics covers Electrical signature analysis, Sight Machine covers Unified plant data model.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Samotics

  • SAM4 only sees what reaches the motor electrically, so it covers the driven train and misses un-driven equipment, structures, process conditions and anything downstream of a mechanical decoupling.
  • Each monitored motor needs hardware installed in the motor control centre by a qualified electrician, and in older switchrooms that installation, including any required outage, can cost more than a year of the subscription.
  • Per-asset subscription pricing means the cost scales linearly with the number of motors, so a plant with a thousand small motors faces a bill that a fixed-price plant-wide vibration system would not impose.
  • Electrical signature analysis on variable-speed drives is harder than on direct-on-line motors, and results vary with drive type, so a heavily VSD estate should insist on a pilot on its own drives before committing.
  • Nothing is published on price, contract length or minimum deployment size, and the vendor sells multi-year subscriptions, so early exit terms are a negotiation you have to raise yourself.

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 Samotics or Sight Machine better?
Neither clearly leads. Samotics 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, Samotics or Sight Machine?
Samotics starts at On request and Sight Machine at On request.
Does Samotics or Sight Machine run on more platforms?
Samotics runs on Web, Cloud. Sight Machine runs on Web, API.
What is Samotics best used for?
Samotics is most often used for a water utility monitoring submersible and borehole pumps that no vibration sensor can be fitted to without lifting the pump, a chemical plant with assets in atex zones where certifying and maintaining in-field sensors is more expensive than the monitoring itself, a food plant that wants pump and mixer condition data without opening guarding or taking a hygiene-critical line down to fit sensors, a site building an energy reduction case, where measured motor efficiency and waste give the business case a payback that reliability alone would not. Of those, a water utility monitoring submersible and borehole pumps that no vibration sensor can be fitted to without lifting the pump and a chemical plant with assets in atex zones where certifying and maintaining in-field sensors is more expensive than the monitoring itself are not what Sight Machine is typically brought in for.
What can Samotics do that Sight Machine cannot?
Samotics covers Electrical signature analysis, Switchroom installation, Energy and efficiency measurement, Submersible and hazardous area coverage. Sight Machine covers Unified plant data model, Broad ingestion, Cross plant benchmarking, Root cause analysis.

Answered from the vendors’ own pages

Samotics: Does Samotics replace vibration monitoring?

For motor-driven assets it often does, and it reaches assets vibration cannot. For un-driven equipment and structures it does not apply at all.

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.

Samotics: Do I have to buy Samotics hardware?

Yes. SAM4 requires the vendor's sensors fitted in the motor control centre; there is no software-only option.

Sight Machine: Does it need a historian?

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

Samotics: Does it work on variable-speed drives?

It can, but performance depends on the drive and the operating profile. Pilot it on your own VSD assets rather than accepting a reference from a direct-on-line site.

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.

Samotics: How is it priced?

Subscription per monitored asset, quoted, typically on a multi-year term, with hardware and electrical installation on top.

Sight Machine: Who is the buyer?

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