The VR504 barrier laser
was developed for the requirements of the steel industry. This powerful
barrier laser is designed for penetrating the heaviest steam and furnace
flames; yet it is a totally safe Class 1 Laser. This dependable barrier
laser works even under the most difficult conditions, such as high
temperatures, vibration, high dust concentrations and contamination,
without problems.
The VR504 barrier laser is available in three models to suit individual
requirements. All models include a 2 Amp, 30VDC/125VAC Form C relay
output. Green “Power” and Red “Alarm” LED’s provide a visual indication
of operation and alarm state. Model VR504-K includes a secondary alarm
output, adjustable to a predetermined level for indicating lens
contamination and misalignment. Model VR504-T operates at a faster
detection frequency and includes an adjustable alarm response time from
8 - 350 msec.
