IR Sensor




• Increased up time & reliability / reduced risk of downtime• Increased operator and facility safety• 24x7 real-time Remote & Local view of status / alarms• Increasingly recognized as the future standard for the oil and gas industry• Latest non-contact IR sensor technology monitors INSIDE panels• Detect faults even at low load conditions

In today’s commercial environment the continued operation of mission critical buildings now has the objective of zerounscheduled downtime and minimal scheduled downtime.The most common cause of electrical failure are bad connections. These cannot be detected via metering or load measurements, power quality etc. However, the thermal increase can be detected using thermally sensitive devices.

 







Current Technology
Thermal imaging inspections are normally carried out once or twice per year (1 or 2 out of 365). Also, the inspections are done from OUTSIDE the enclosure in which the equipment is located. Even thermal windows don’t overcome the problems; they improve the view from camera to target, but don’t resolve some key issues, like how to inspect targets with no direct line ofsight, nor the fact that the inspections remain periodic, and also add significant cost.
The Next Technology Step
Exertherm provides a major breakthrough by providing 24x7CONTINUOUS Thermal Monitoring from INSIDE the enclosure, rather than periodic inspections from outside. Exertherm provides capability for data logging / on-going trend analysis and user definable alarms. Warning and critical alarms can be configured which trigger in the event the temperature of any monitored component exceeds the pre-set limits. Exertherm is easily installed (new/ retro) & integrates with most BMS/ SCADA systems.

 


How it works...
1 Exertherm utilizes small plastic, non-contact IR sensors which require no external power, have lifetime calibration & deliver ΔT measurement. These are placed INSIDE the enclosure, directly monitoring key connections.2 Cable joints can be monitored using a patented cable sensor which straps to the cable & delivers ΔT measurement.3 These connect to data cards (8 per card), which collect condition & transmit the data to the host system.4 Data cards utilize industry standard ModBus protocol for easy integration.5 Delivering the data to an existing BMS system is a straight forward process.6 This facilitates the thermal monitoring of all critical equipment, not just in one building, but for any location via WAN Intranet/Wireless etc.
