03 / Resolution vs accuracy

Three parameters, three rows

Position resolution is the step the distance moves in; the locating figures are wider and never share its row.
Parameter Published value
Position resolution 0.1 m, the step the reported distance moves in
Locating accuracy ±0.6 m plus 0.5 % of cable length
Locating repeatability ±0.6 m plus 0.25 % of cable length
Worked at 100 / 250 / 500 m, accuracy · repeatability ±1.1 and ±0.85 m · ±1.85 and ±1.23 m · ±3.1 and ±1.85 m
100 m 300 m 500 m ±1.1 m ±3.1 m
Accuracy band

No datasheet here publishes a locating accuracy at that granularity. The tolerance decides how much capacity is isolated to chase one drip.

06 / Standards

What the installation has to satisfy

UL 61010-1

EN 61010-1, IEC 61010-1, CSA C22.2 No. 61010-1.

Controllers

CE

Declaration of conformity.

Controllers, power supplies

UL CL2P

Meets NFPA 262.

Underfloor cable

Also carried: UL 719 (jacket abrasion, 60 to 65+ cycles), IEC 60730-2-23:2025 (sensing elements), IEC 62368-1 (loop proof at 1.5×). Ingress protection is not specified in this product class; the ratings carried are NEMA Type 1 and UL CL2P plenum. Certification names are published on the badge cards; approval documents are shown on request.

07 / Accessories

Rules that keep a loop supervised

Leader, 4.6 m

Returns the specification sheet, the dimensional drawing and the lead time. One working day.

Specification request

Ask for the specification sheet

Leave your work email and the model code. One datasheet per model, with position resolution and locating repeatability stated as separate rows.

  • A specification table of at least ten rows per product family, and a downloadable PDF for every model listed.
  • Seal-life data where it decides the choice: permeation rate, compression set and fluid compatibility.
  • One working day for a reply, from an engineer rather than a catalogue autoresponder.
