Magnetostrictive linear position sensors for extreme environments

Whenever you need to measure with absolute precision in extreme conditions, you can count on the BTL robust magnetostrictive linear position sensors from Balluff. Our systems are made entirely of stainless steel and are designed in protection classes up to IP69K or for high pressure cylinder applications up to 1000 bar. Their non-contacting working principle guarantees to prevent wear and ensure an almost unlimited service life. Balluff offers the highest tier of reliability and precision, even in harsh environments.

• Rugged stainless steel housing
• Exceptionally shock- and vibration-resistant
• Extreme waterproofness, IP69K
• Temperature range of -40 to +85 °C
• High-pressure resistance rated up to 1000 bar
• Resolution of up to 1 µm
• Measuring lengths of up to 7620 mm
• Non-contacting, thus free from wear – no downtimes
