PRV

Sensor for Iron & Steel IndustryHMD

It operates by detecting infrared rays (heat rays) radiated from the heat material. Composed of an amplifier unit, sensor head, and heat-resistant fiber unit, it is ideal for detecting steel materials at steel plants and heavy industry in harsh environments. Detectable hot metal temp is 360 to 1,200 degrees C

Overview

Features

This equipment detects radiant heat from the material. It 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. are not required for 350 to 1,200 degrees C. It is epoch-making HMD that operation point setting is possible with detecting condition before operation.

Flexible power source range

It is capable of being used within the scope of 100 to 240VAC.

Sensor head is not required water-cooling or air-purge

Water-cooling or air-purge isn't required for sensor head because non-air dust purge hood is applied.

Warning output is provided
