Hot Metal Detectors

The Hokuyo LAV series is a laser-based optical fiber type hot metal detector (HMD) that contains a separately housed emitter and receiver, heat-resistant fiber cables and heavy-duty sensor heads. Equipped with high-powered laser diodes, this device operates effectively in high-temperature harsh production areas where dust, steam and vapors are present. With accurate long-range transmission, this through-beam system operates effectively in mill environments by detecting passing material on a process line that interrupts the infrared laser beam.

The Hokuyo MBX series is a non-contact hot metal detector (HMD) that uses microwave transmission for detecting hot steel. This system integrates a control unit, stainless waveguide and remotely mounted antenna stand. For the most severe applications where dust, smoke, vapors, high temperatures, induced noise or intense ambient light are present, this non-invasive sensing system is ideal for reliable detection of hot material in a continuous casting line, pipe or rolling mill.

The Hokuyo PX-DX/WX series is an economical through-beam type hot metal detector (HMD) that is used where lower ambient temperature areas are present within the steel manufacturing process. This model consists of a separate emitter and receiver equipped in compact self-contained housings. With accurate long-range transmission, this through-beam sensor operates effectively in mill environments by detecting passing material on a process line that interrupts the modulated light beam.

The PHV-10 series is an LED-based optical fiber type hot metal detector (HMD) that contains a separately housed emitter and receiver, heat-resistant fiber cables and heavy-duty sensor heads. With accurate long-range transmission, this through-beam system operates effectively in mill environments by detecting passing material on a process line that interrupts the modulated light beam.

• Metal and Steel

The PRV-10 series Hot Metal Detector (HMD) is an electronic controller that includes the infrared detection cell, amplifier and electronic outputs in an aluminum die-cast housing. To accommodate variation in product temperature and background radiation, three levels of infrared thresholds are selectable with an internal switch and sensitivity adjustment knob. Combined with flexible stainless steel fiber cables and interchangeable sensor heads, this radiant-heat detection system can be standardized throughout the mill.
