Frequently Asked Questions
What does PT9101-0100-114-3160 mean?
A Celesco PT9101 with 100-inch stroke (0100), aluminum enclosure with 18 oz tension (1), Ø.034" nylon-coated stainless cable (1), bottom cable exit (4), 5000 Ω potentiometer sensing circuit (3) and 10 ft. pressure-tested waterproof cable rated IP68/NEMA 6P (6).
Which PT9101 sensing circuit should I order?
Options 1–4 are potentiometers from 500 Ω to 10 KΩ — ideal for direct voltage-divider readings. Option 5 is a fixed 2 mV/V bridge for ratiometric A/D inputs; option 6 is an adjustable 0–30 mV/V bridge when you need to match a specific span.
How does PT9101 differ from PT9420?
Identical mechanics and option structure, but the PT9101 outputs a resistance (500 Ω–10 KΩ pot or mV/V bridge) while the PT9420 outputs a 4–20 mA / 0–20 mA current loop signal. In the code, the difference sits in the D digit (sensing circuit) versus the E digit (current output).
