Industrial Heat Monitoring: How to Make it Simple

Thermal monitoring systems are an effective way of pinpointing issues in industrial environments before they progress into problems. Continuous heat monitoring can facilitate incisive process optimization, timely preventative maintenance, and quick identification of safety issues.

The IND Thermal sensor supplied by Terabee is a relatively inexpensive alternative to traditional IR cameras, utilizing thermopile array technology to offer spatially resolved thermal monitoring at a good price.

In terms of wavelength, infrared (IR) light lies just beyond the visible spectrum of light. While the human eye can see light with wavelengths up to around 750 nm, infrared light has wavelengths between 760 nm to 1 mm.

Though invisible, this range of the electromagnetic spectrum contains information considered to be extremely useful: all objects emit infrared light, and to establish the intensity of this infrared glow, the object’s temperature must be observed.

If it was possible to see infrared light, it would be possible to determine the temperature of objects just by looking at them.

This is the foundation of the logic on which infrared cameras are built. Infrared cameras, or thermal cameras, are devices that have the capacity to ‘see’ in infrared. This gives them the ability to observe the temperature of any object within their field of view.

Seeing the infrared spectrum provides major advantages when situated in industrial environments. Thermal imaging cameras enable the identification of a range of safety-critical or process-critical from their telltale thermal emissions.

For instance, such devices can determine if processes are running too hot (or too cold), if the equipment is overheating or if a conduit is leaking.

This not only facilitates the enhancement of process optimization and equipment maintenance but can also significantly improve safety by giving warnings or alarms in response to fire hazards.

Terabee IND Thermal Camera

Ultra-versatile with a small-footprint, the Terabee IND Thermal is a thermal imaging camera designed to offer a number of advantages that come with industrial thermal vision at a low cost.

The Terabee IND Thermal is one of the most compact and lightest multi-pixel industrial thermal cameras on the market.

Providing a 32x32 pixel resolution across a 90º  field-of-view (FoV), the IND Thermal utilizes a thermopile array to identify temperatures over a broad spectrum without the need for calibration beyond the factory.

IP65 ingress protection level makes it well-suited to dirty industrial environments, while Modbus transmission protocol via RS485 makes it easy to integrate, ensuring compatibility in automated factories.

As standard, the IND Thermal is fitted with three alarming applications which the user can selectively enable or disable. Full or partial area analysis allows users to determine the minimum and maximum thresholds for distinct areas within the field of view.

Where necessary, the mean temperature can be quantified in each of these regions and contrasted against user-set thresholds, triggering alarms.

The IND Thermal smart temperature sensor is well-suited for a number of applications.

Machine and Equipment Monitoring

The Terabee IND Thermal allows inexpensive, continuous monitoring in order to put an end to manual spot checks. Its compact, lightweight form factor means it can be stationed anywhere and used to monitor motors, pumps, and clutches for overheating, wear, or overload.

Bespoke warnings and alarms can be programmed to instantly alert personnel when safe operational limits are reached, enabling timely preventative maintenance before expensive failures crop up.

Inline Process Monitoring

Thermal dynamics play a critical role in numerous production processes, and stationing inline thermal monitoring can generate key data to better understand and enhance these processes.

The IND Thermal sensor can supply users with product statistics (include min/max, average, and outliers) which enable optimal decision-making processes with regards to production, boosting throughput, and limiting defects or failures.

Area Monitoring

In hazardous environments, heat monitoring is especially valuable when there is an explosion risk.

In such environments, the IND Thermal can be utilized to monitor storage, bunkers, or open areas to identify overheating and hotspots before they hit hazardous levels and thus trigger early fire warning systems before fires occur.

Many alarms or automated feedback can be set to automatically trigger in response to certain heat monitoring parameters to avoid fires or explosions.

Optimized for Embedded Applications

The small-footprint of the IND Thermal makes it well-suited to embedded and inline applications. Embedded intelligence (EDGE processing) enables onboard data processing and local feedback loops to significantly reduce the necessity for external computation.

Direct feedback from the sensor can be employed to raise alarms and activate events or emergency stops. These outputs can also be utilized as direct inputs to PLCs or relays in the event of an alarm situation.

Simple connectivity and networkability –  enabled by a GUI and Modbus RS485 interface – make the IND Thermal well-suited to unconventional automated monitoring and optimization for the Industrial Internet of Things (IIoT).1 Sturdy and dependable, the IND Thermal is compliant with VdS certification.2
