Product Group | Spark- and Ember Detectors

The Canadian company Hansentek produces high performing and quality spark and ember detectors. These detectors are vital in running a safe operation and protect air ducts and conveyers in a large variety of applications.

Spark detection systems are crucial safety measures used in air ducts to prevent potentially catastrophic fires and explosions. These systems are designed to swiftly detect and extinguish sparks that may arise from various industrial processes, such as grinding, welding, or cutting, which can inadvertently enter the ventilation systems.

Using advanced sensors and monitoring technology, the spark detection system can identify any hazardous particles and activate countermeasures within milliseconds. Countermeasures that will be triggered can be water or foam sprays, shutting down machinery or isolating the affected duct section via an abort damper.

By effectively mitigating fire risks at the source, spark detection systems play a vital role in safeguarding industrial facilities, protecting employees, and preventing costly damages to property and equipment. Their ability to act instantaneously makes them an indispensable asset in maintaining a secure and productive working environment.

Spark & Ember Detectors

Hansentek Ember detectors operate in a similar way compared to spark detection. The biggest difference is that these units are light tolerant and can therefore be used on open conveyers. Once an ember is detected, the system can automatically trigger various responses, including activating water sprays, foam suppression, or halting the conveyor’s operation altogether.

Swiftly identifying and extinguishing embers can prevent fires from spreading along the conveyor line, reducing the risk of damage to valuable machinery and products, as well as avoiding potential harm to personnel. Ember detection on conveyors is an essential investment, as it enhances operational safety, minimizes downtime, and safeguards industrial facilities from the devastating consequences of fire outbreaks. By swiftly addressing potential ignition sources, businesses can ensure uninterrupted productivity while maintaining a secure work environment.

FAQ

A spark detector is a device designed to detect and respond to sparks or other incandescent particles that may indicate the presence of a fire hazard. It is commonly used in industrial settings where sparks or hot particles can pose a risk, such as in manufacturing processes involving flammable materials or in equipment where friction or electrical discharges may generate sparks. Here’s a simplified explanation of how a spark detector typically works:

  1. Detection Method: Spark detectors employ various detection methods, depending on the specific design and application. Common detection methods include optical detection and thermal detection.
  2. Optical Detection: Optical spark detectors use sensors that detect the presence of sparks or hot particles based on their light emission characteristics. They typically employ photodiodes or phototransistors to detect the sudden increase in light intensity caused by sparks. Optical detectors can also detect other sources of light emission associated with combustion, such as flames.
  3. Thermal Detection: Thermal spark detectors utilize temperature sensors or thermocouples to detect the heat generated by sparks. When a spark is present, the sudden temperature rise triggers the thermal detector, indicating the potential fire hazard.
  4. Signal Processing: Once a spark or hot particle is detected, the spark detector’s electronic circuitry processes the signal from the detection sensor. It analyzes the signal characteristics, such as the duration, intensity, or frequency, to determine if it corresponds to a potential fire hazard.
  5. Alarm Activation: If the detected signal meets the predefined criteria indicating the presence of a spark or hot particle, the spark detector triggers an alarm or activates an appropriate response action. This can include activating fire suppression systems, shutting down equipment, or providing visual or audible alerts to personnel for prompt intervention.

It’s important to note that the specific implementation and features of spark detectors may vary depending on the manufacturer and application. Some spark detectors may incorporate additional features, such as adjustable sensitivity levels, delay timers, or integration with control systems for automated response actions.

Spark detectors play a crucial role in industrial fire prevention by providing early detection and prompt response to potential fire hazards caused by sparks or hot particles. They help mitigate the risk of fires in environments where such hazards are present, protecting personnel, equipment, and property.

An ember detector, also known as an ember sensor or ember monitoring system, is a device designed to detect and respond to embers or glowing particles that can be carried by air currents and pose a fire hazard.
