Is DHMSCare suitable for turbines that need proximity probes and API 670 protection?
No. DHMSCare does not replace an API 670 machinery-protection system or its proximity probes; keep that system on the turbine and use DHMSCare on the plant's pumps, fans and motors. API 670 is the industry standard for machinery protection systems.
Proximity probes are sensors that measure shaft movement directly.
Protection and monitoring are two different jobs
A protection system watches the turbine shaft and must stop the machine within milliseconds when a limit is crossed. That is why it is a wired system built for that single task.
DHMSCare is a monitoring system, not a machine-protection system, so it does not trip or stop machines automatically. It warns your team early, and people decide when to stop a machine.
Where DHMSCare fits in a power plant
The best fit is the auxiliary equipment around the turbine: fans, pumps, motors and gearboxes. A failure in any of them can cut the unit's output, even while the turbine runs well.
At a coal-fired plant, DHMSCare warned of misalignment on a secondary air fan eight days before it became severe. The same plant later reported a 65% drop in unplanned shutdowns.
What to expect on site
DHMSCare sensors are wireless accelerometers mounted on bearing housings. They measure vibration on the machine surface, not shaft movement, so they do not replace proximity probes.
Installation needs no downtime. Data stays on nodes inside the Chinese mainland and does not leave the country; central and state-owned enterprise projects can run on-premises in the customer’s own server room.
Next step
Turbines keep their API 670 protection; DHMSCare adds continuous monitoring for the plant's pumps, fans and motors, so the two systems cover different jobs and maintenance gets its evidence.

Questions buyers also ask
Can DHMSCare monitor the turbine bearings at all?
DHMSCare makes no turbine claim. Keep the turbine on its protection system, and use DHMSCare on the pumps, fans and motors around it.
Should we keep our protection relays when we add DHMSCare?
Yes. Keep your existing protection relays and trip systems in place, because DHMSCare monitors and never trips a machine.
Which auxiliaries should we start with?
Start where a stop costs the most, such as the fans and the boiler feed pumps. The help page on boiler feed pumps, fans and cooling-tower gearboxes covers sensor placement.
