Hokuyo PRV-10 LED Type Optical fiber type HMD
Hot metal with 360 to 1,200 degrees C
Setting of sensitivity adjustment against temperature of detecting material had not been obvious. However this equipment displays reception level lamps in every twice using linear characteristic relationship between temperature and analog output voltage(8 levels). Operation setting can be made with level display or analog voltage. Also, there are three ranges, L/M/H as detection temperature changeover switch. Any parts such as slits etc. aren't required for 350 to 1,200 degrees C. It is epoch-making HMD that operation point setting is possible with detecting condition before operation.
・This device doesn't specify power source. It is capable of being used within the scope of 100 to 240VAC.
・Water-cooling or air-purge isn't required for sensor head because non-air dust purge hood is applied.
・Warning output is provided.
・We have wide variety of sensor head. Refer to data sheets of head.
