Sensors inside switchgear enclosure
check hotspots
The need for continuous thermal monitoring of key components within electrical switchgear enclosures has been a desire that can now be met.
The consequences of an unforeseen electrical outage can be catastrophic for businesses where power is "mission critical" The need for continuous thermal monitoring of key components within electrical switchgear enclosures has been a desire that, until now, could not be met

Continuous thermal monitoring reduces downtime
QHi Group has developed the Exertherm system, a continuous infrared temperature monitoring system that can detect the rises associated with imminent electrical and mechanical equipment failure.
Infrared sensor claimed to be world's smallest
Infrared thermocouples are small, accurate, non-contact infrared sensors which require no outside power and connect directly to temperature measurement and control instrumentation.
Infrared sensors check temperatures on the move
Where the product is moving, fluidised or delicate, the ability to measure temperature on a non-contact basis is a significant advantage, which is where infrared sensors come in.
Now it can.
The high costs of thermal imaging cameras mean that for most companies only infrequent inspections can be made, i.e a "snapshot".
Also no infrared device can see "through" a solid object, thus components not in direct line of sight to the external panel cannot be inspected.
The ExerTherm System can thermally monitor all key switchgear components on a continuous and non-contact basis by placing sensors inside the switchgear enclosure, The IR sensors measure target temperature as the øC rise on ambient.
Because the sensors are directly monitoring key components on a continuous non-contact basis, they miss nothing your installation is being watched 24 hrs a day 365 days a year.
Small low cost patent protected infrared sensors (IRt/c), which require no power, feed signals via data acquisition cards back to a PC with easy to use but highly effective software.
This includes on-going data logging, trend analysis and individually settable 2 stage alarms per channel, so problems can be identified at a very early stage of development and appropriate action planned in advance thus allowing you to spot power failures before they happen.
ExerTherm can be fitted to new switchgear, or retro fitted to existing installations.
It can be subsequently expanded and will connect to most building management systems.
This unique system has already been specified and installed on many prestigious projects one of the latest being a new European HQ building based in London Docklands.
