High Amp Sensor for Predictive Maintenance Sensor

Good morning!

I am hoping to use your PR-55-20A Predictive Maintenance Senor to monitor the chillers at our factory. Will the stock AC Current sensors work in the range of 200 - 400 amps? If not would you have any recommendations and if so would using different AC Current sensors require different firmware?


Hi Jeff,
In order to support high Amp sensor we will have to change the CT and the electronics.
we have released a new version of PM sensor

The sensor has tons of improvements. the vibration sensor probe is now using a different protocol and has metal shielding around it. the sensor also provides alot more info related to machine health.


That looks fantastic. What would be the best way for me to return 4 of the PM sensors I have (Never deployed) and get 4 of these set up to handle 300+ amps? Any special instructions or anything?

You can submit an RMA for returns.
