Selection

When to Choose SE-PR30

The installation is in a hazardous area and needs an intrinsically safe sensor.
Space only allows a Ø17 mm integrated head.
The controller reads 0.5–4.5 V ratiometric-style signals.

FAQ

SE-PR30 — Frequently Asked Questions

What are the intrinsic-safety parameters of SE-PR30?

The SE-PR30 datasheet lists Ui 12.5 V, Ii 15 mA, Ci 0 µF and Li 0 mH. These values are used to check compatibility with the barrier or isolator in your system. Ex certification is applied for under the SE series name, and certificate details are provided with the quotation.

Why does SE-PR30 use an SE part number instead of SGM?

All SEGMENsensor explosion-proof models — intrinsically safe or flameproof, position or level — use the SE prefix so that hazardous-area versions are recognisable from the part number alone.

What is the measuring range of SE-PR30?

SE-PR30 is orderable from 25 to 4000 mm in 5 mm steps. Longer ranges and special temperature or pressure versions are available on request.

How do I read the SE-PR30 ordering code?

The code follows SE-PR30-<ring>-<range>-<output>-<connection>[-options]. For example SE-PR30-R40-00900-V3F-L12 means: Ring OD40, 900 mm, 0.5–4.5 V, M12 pigtail. The full option list is in the ordering-code table on this page and in the datasheet.

What is the MOQ and lead time for SE-PR30?

MOQ is 1 piece. Samples ship in 5–7 working days, production orders in 3–5 weeks, and we reply to every RFQ within 24 hours.
