Frequently Asked Questions
What does PT101-0100-111-2130 mean?
A Celesco PT101 with 100-inch stroke (0100), standard cable tension (1), top cable exit (1), 1000 Ω potentiometer sensing circuit (2) and a 6-pin metal connector with mating plug (3).
What does the H tension option mean on a PT101?
Order code H selects the high-tension measuring cable (±40% tolerance) — roughly double the standard cable tension (e.g. 26 oz vs 5 oz at the 5-inch range). Choose it when vibration or cable sag could affect reading stability.
How compact is the PT101?
The PT101 body is roughly 2.4 × 2.4 × 1.1 in. with strokes from 2 to 100 inches — one of the smallest cable-extension sensors Celesco makes, common on test benches and medical/fitness equipment.
