PT101, Draw Wire Displacement Sensor
- Absolute Linear Position
- Classic String Pot Design
- Stroke Range Options: 0 - 2 to 0 -100 inches
- Powder Painted & Anodized Aluminum Enclosure
- Industrial Automation & Testing Applications
The PT101 by Celesco is rooted in a design that dates back to the late 1960s and has become a staple in various fields, from aircraft structural testing and hydraulic cylinder control to valve stem opening and industrial automation. It offers a comprehensive range of full stroke options from 2 to 100 inches. The PT101 stands out for its straightforward installation process, not requiring perfect parallel alignment, and its robust design featuring a powder-painted and anodized aluminum enclosure.
This sensor generates a voltage divider output signal that is linearly proportional to the position of its traveling stainless steel measuring cable, ensuring precise feedback for extensive applications. The PT101 is celebrated for its instrument-grade accuracy, ranging from ±0.25% to ±0.10% full stroke, along with its exceptional repeatability and essentially infinite resolution.
