Flame Scanner Sensor YFD-7-2122H

Product Description

  YFD-7-2122H fire detection probe / flame detector [European measurement and control]

  The EI instrument measurement and control YFD-7-2122H fire detection probe / flame detector is a microprocessor device using a solid flame detection sensor. It has an internal relay that automatically sets the ON/OFF threshold, so the remote amplifier or flame switch can be eliminated.

  The YFD-7-2122H detects the modulation amplitude (ie, the flickering characteristic) produced by the target flame and detects a wide frequency. In the probe setup procedure, the amplitude of the target flame will be automatically stored along with the optimal ON/OFF value. The corresponding sensor gain will also be automatically selected. The probe combines all self-diagnosis and electronic self-test functions.

  The YFD-7-2122H fire detector/flame detector requires 24Vdc power supply, is connected to the cable through an 8-pin electrical quick connector, and has a standard 4-20mA flame intensity signal output.
