Benefits of QVLA®
- NO MAGNETS
- Unlike magnetic fields vulnerable to outside forces, QVLA® is a contained signal. QVLA® has been tested in environments of electrical fields to 1,700,000 volts at 700,000 amps with no effect.
- NO FERROUS METAL NEEDED
- QVLA® works with cardboard, plastic, wood, metal, anything able to set up a barrier to light.
- WELD FIELD IMMUNE
- LESS EXPENSIVE
- Lower initial cost
- Solid state electronics last much longer than reed switches or potentiometers keeping repair and maintenance costs down
- No magnets to weaken over time. LED life determined to be decades
- Seals tested to greater than 1000 miles, guaranteed to 500 miles. Tie-rod air cylinder with iNSiGHT®is repairable.
- No lubrication to purchase or maintain with iNSiGHT® — assembled dry, operates dry
- No extra machining needed
- No sending unit needed
- No speed limit
- Go as fast as you can, no worries about running over reed switches, no worries about reducing magnet life by actuator speed.
- CLEANER
- No oils or lubricants; assembled dry, operates dry.
- FIBER OPTIC READY
- Remote hazard sensing
- MEASURES VOLUMES
- Cylinder, Trapezoid, Sphere, Cubes etc.
