Frequently Asked Questions
What does PT8101-0040-311-4130 mean?
A Celesco PT8101 with 40-inch stroke (0040), 303 stainless steel enclosure with standard tension (3), Ø.034" nylon-coated cable (1), 10,000 Ω potentiometer output (4), 25 ft. instrumentation cable (3) and standard nylon cable guide (0).
How does PT8101 differ from PT8420?
Same housing, ranges (2–60 in.) and option structure. The PT8101 outputs resistance (500 Ω–10 KΩ potentiometer or mV/V bridge); the PT8420 outputs a 4–20 mA / 0–20 mA current loop.
Which cable guide option should I choose?
Code 0 (standard nylon) suits most uses. Code 1 (stainless steel guide) for corrosive or high-wear areas, code 2 (polyurethane bellows) to keep debris off the cable, code 3 (integral cable brush) for heavy particulate environments.
