Busbar temperature sensors into PM8240

[nigel_greenwave]

Hi,

We have a client request to monitor the temperature of there busbar's within a Data Centre. Each busbar has a PM8240, so we are thinking of adding a Analog card to each PM8240, and wire 4 (A:B:C:N) temperature sensors into it.

Can anyone recommend a wired (wireless is a no no within our clients DC's?) temperature sensor that is suited for measuring the temperature on a busbar?

By using Type-K or any thermocouple  connect to Analog input then convert to temperature.

See ION Reference on Analog Input Module and Arithmatic Module use Type-K or other linearization function.

This is the beauty of ION meter in which you can do customization.

Just be sure to take adequate precaution to ensure required safety & electrical isolation barriers are in place between the busbar and thermocouple... Those Analog inputs are low voltage and not rated for bus bar voltages.

Google searches show several 3rd party wired modules for this application (thermo couple output, analog 4-20mA, modbus, etc), however I could only find wireless offers from SE.

What we are planing do to, is to try is using a 4-20ma contact temperature sensor and strapping it on the cable near the  copper connection point (60-80mm away from the copper). If there is a lose connection or over loading the cable should heat up.

Hi have checked with Canalis and OKKEN Marketing and they do not have specific recommendation concerning temperature sensors for their offers.

Currently, the best solution pushed by Marketing is to use TH110 or CL110 sensors with ZBRN32 or PowerTag Link... but this is a Wireless solution.

PME2020 introduced a new thermal monitoring driver for the Exertherm ARM XL device:

The "Datacards" the ARM XL uses are actually serial Modbus devices that could be connected as slave devices on a PM8000's serial port if you don't need the HMI.  The Modbus map is fairly simple, and the power of ION would make it straightforward to integrate.  These Datacards support several different types of sensors too - and they're wired.
