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.; Yokogawa CENTUM VP there is no published price list and no way to size a budget without engaging Yokogawa or an EPC, so early-stage comparison against DeltaV or Experion is guesswork until quotations arrive.
  • They diverge on capability: Samotics covers Electrical signature analysis, Yokogawa CENTUM VP covers Field Control Station.
  • 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.

Yokogawa CENTUM VP

  • There is no published price list and no way to size a budget without engaging Yokogawa or an EPC, so early-stage comparison against DeltaV or Experion is guesswork until quotations arrive.
  • Engineering and commissioning routinely cost several times the hardware and software, and owners who budget from the equipment quote alone are consistently short.
  • The ecosystem is closed: controllers, I/O and diagnostics are Yokogawa, and third-party alternatives at the controller layer do not exist, so the vendor holds pricing power for the twenty years or more the plant runs.
  • Operator stations run on Windows and are tied to specific validated Windows releases, so operating system end-of-life forces console refresh cycles that are governed by Yokogawa validation rather than by your IT policy.
  • Engineering staff who know CENTUM are scarce outside Japan, the Middle East and South East Asia, and in North America and Europe you will pay a premium or depend on Yokogawa’s own services organisation for changes.

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.

Yokogawa CENTUM VP: Can I upgrade from CENTUM CS 3000 without rewiring the plant?

Yes. Yokogawa sells migration packages that replace the controller and keep existing field wiring and marshalling, which is the main reason CENTUM installations stay CENTUM.

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.

Yokogawa CENTUM VP: Is CENTUM VP sold as a subscription?

No. It is a capital purchase of hardware and licences with an annual service agreement for updates and support.

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.

Yokogawa CENTUM VP: How does it compare with Emerson DeltaV on cost?

Neither publishes prices. CENTUM tends to win on brownfield migration cost because the field wiring stays; DeltaV tends to be cheaper on small greenfield systems.

Samotics: How is it priced?

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

Yokogawa CENTUM VP: Do I need a separate safety system?

Yes, for SIL-rated functions. ProSafe-RS is the Yokogawa SIS and shares the CENTUM engineering database and operator console.
