Industrial Sensors / FD-A300P Series Hot metal detector/sensor

FD-A300P Series Hot metal detector/sensor

Description

FD-A300P is an optical fiber hot metal detection photo sensor (HMD) that directly detects infrared energy emitted (in the 0.8 to 1.8um range)  from heated material (steel products, etc.). This model comes equipped with an 8-bit microcomputer, and is an intelligent hot metal detection sensor integrating the following features:

  • Auto sensitivity optimization (with manual overide capability)
  • Dual Temperature ranges (High/Low)
  • Scaled real time Display of received Intensity
  • Recall of Maximum intensity of the last 8 detections
  • Stability check of 3 different threshold parameters (flashing LED & relay output)

Amplifiers

Amplifiers in this product range should be considered for compatible relay output and required response time; all other parameters are the same between the 4 available models.

Select a hood, amplifier, and fiber combination; based on the temperature range and size of the detection object. The temperature range varies depending on the fiber length and distance to the object to be detected. Temperatures shown in the table below are applicable only when the heated material (object) is larger than the detection field of view. If the material is smaller than the detection field, the lowest detectable temperature is higher than shown in the chart.

Optical Head Field of View explained

  The Field of View (FOV) can be a critical parameter in the selection process to maintain reliable object detection. If the object to be detected fills or overfills the FOV, there is no issue with repeatable detection or Minimum Resolveable Temperature (MRT).

However if it does not fill the FOV you may want to consider either a Narrow FOV head (please note the temperature shift to higher MRT), or consult the graphs and coefficient (K) calculations <by clicking here> to get a better understanding and estimates of the correct combination of Fibers, heads, and amplifier for your application.

When calculating your best fit; please note the correlation to distance, as relates to the FOV within the cone sensed by the system.

Features


  • Auto sensing mode automatically adjusts the operation level according to the received light intensity at detection of heated material; there is also a manual mode that allows manual setting of operation level.
  • One sensor for a wide range of temperatures with Two different ranges for low and high temperatures can be chosen.
  • Numerical indication of received light intensity convenient for operation level monitoring.
  • Maximum received light intensity 8 most recent objects detected is stored to allow viewing later.
