Spark Detector - Sensors

FM 1/8 - DLD 1/8A - FM 3/8 - TM 1/8Detect sparks, burning embers and heat

GreCon sensors detect even the smallest spark's or burning ember's infrared radiation. The sensors will signal the control console to initiate instantaneous countermeasures. This action will prevent the spark from entering the dust collector or other downstream areas. Four basic sensor models are available for a wide range of applications.

  • FM 1/8 spark detector sensors contain photo diode elements that detects a spark or burning ember's infrared radiation and signal the control console.

  • DLD 1/8 (daylight) sensor uses a similar detection principle, in applications where ambient light is present.

  • FM 3/8 for high temperature or high pressure applications, the fiber optic cables carry the IR energy to separate photo diodes within the sensor.

  • HPD 1/8 detector reliably detects dangerous hot particle potentials in low, non-glowing temperature range.

  • TM 1/8 heat sensor detects the temperature rate-of-rise and is activated at various preset temperature levels.
