SEGMENsensor magnetostrictive position sensor — replacement by specification

Key facts

Replacing an installed magnetostrictive position or level sensor starts with its specification, not its brand. SEGMENsensor matches the stroke, mounting, output, connector and pressure rating of the installed sensor to an SGM or SE part number from its datasheets, and states what matches and what differs before you order.

Magnetostrictive Series by Installation

Pick the series by how the installed sensor is mounted, then check range, output and pressure on the series page.

Cross-Referencing in Six Steps

A replacement is confirmed on paper and on a sample before production — never assumed from a headline specification.

1. Send the existing data
Label photo, part number, datasheet or drawing, and the application: medium, pressure, temperature, controller input.
2. Specification match
We compare every parameter with our SGM / SE datasheets and list what matches and what differs.
3. Drawing and wiring table
You receive the dimensioned drawing and pin assignment of the proposed part number for approval.
4. Sample
Samples of 1–5 pcs ship in 5–7 days for fit and signal checks on your machine.
5. Production
Production lead time and MOQ are confirmed with the quotation. OEM volume supply; custom options confirmed with the quotation.
6. Documentation
CE and RoHS documentation with every order; explosion-protection certificate for SE-series models.

Frequently Asked Questions — Magnetostrictive Sensor Replacement

Common questions from engineers replacing an installed magnetostrictive sensor. Email info@segmensensor.com for application-specific advice.

What does "magnetostrictive sensor replacement" mean on this page?
It means replacing an installed magnetostrictive position or level sensor with a SEGMENsensor SGM or SE part number that meets the same application specification. We do not copy or claim equivalence to any other manufacturer's product. We cross-reference by specification: measuring range, mounting, output, connector, pressure rating, protection class and operating temperature are compared with our datasheets, and we tell you which parameters match and which differ before you order.
What information do you need to cross-reference an existing sensor?
Send the data from the label and datasheet of the installed sensor: measuring range (stroke) and any null or dead zones, housing type (rod in cylinder, external profile, level rod), mounting thread and flange dimensions, output signal (4–20 mA, 0–10 V, RS485, SSI with word length, code and resolution), connector type and pin assignment, supply voltage, pressure rating, protection class, operating temperature and the magnet or float in use. A photo of the label and a dimensioned drawing help.
Which SEGMENsensor series fit a hydraulic cylinder?
In-cylinder rod sensors: SGM-PR10 (25–8000 mm, M18×1.5 mounting, 35 MPa continuous / 70 MPa peak, IP67), SGM-PF10 (flat head, 25–8000 mm, 35 MPa, IP68), SGM-PF20 (compact embedded flange, 25–4000 mm, IP68), SGM-PR40 (compact rod, 25–4000 mm, 35 MPa, IP68) and SGM-PR50 (miniature, 25–4000 mm, 35 MPa, IP68). For hazardous areas the SE-PR30 is an intrinsically safe version (25–4000 mm).
Which outputs are available?
Per series, as stated in the datasheets: analog 4–20 mA, 0–20 mA and 0–10 V (0–5 V on SGM-PR20; 0.5–4.5 V, 0–5 V and 4–20 mA on SE-PR30, other outputs such as 0–10 V on request), RS485 Modbus RTU on all SGM series, and SSI on SGM-PR10 and SGM-PE10 (on request on SGM-PR20 and SGM-PF10). Profinet is available on request on SGM-PR10 / SGM-PE10. SE-LX level transmitters offer 2-wire 4–20 mA + HART (parameters settable with a HART handheld communicator), 4-wire 4–20 mA / 0–10 V and RS485. If your installed sensor uses an interface not listed here, tell us — we will say plainly whether we can supply it.
What accuracy do SEGMENsensor magnetostrictive sensors have?
The values are in each series datasheet. SGM-PR10, SGM-PE10, SGM-PR20 and SGM-PF10: non-linearity <±0.01% FS (min ±50 µm), repeatability <±0.001% FS (min ±5 µm), 16-bit D/A analog resolution. SGM-PF20, SGM-PR40, SGM-PR50, SGM-LS10 and SGM-LK10: repeatability ±0.005 mm. SE-LX level transmitters: resolution 1 mm or 0.1 mm. Compare these with the requirement of your application rather than with another product's headline figure.
Will the replacement be mechanically and electrically identical?
Not automatically. Dimensions, mounting thread and connector pin assignment are defined by our datasheet drawings (SGM-PR10 mounting: M18×1.5 or custom-made). Where your installation needs a different thread, flange, cable or pin assignment we check whether it can be built, and we send a drawing and wiring table for your approval before production. Check the magnet or float as well: we supply matched position magnets and floats for each series.
What is the minimum order quantity and lead time?
Qualification samples of 1–5 pcs ship in 5–7 days; production lead time and MOQ are confirmed with the quotation. Custom stroke, connector, output or housing options are confirmed with the quotation, which is sent within 24 hours on working days.
What certifications and documents are supplied?
CE and RoHS documentation is supplied with every order; SEGMENsensor manufactures under an ISO 9001:2015 quality system. For hazardous areas, use the SE-PR30 intrinsically safe position sensor or the SE-LX10 / SE-LX20 / SE-LX30 flameproof level transmitters — tell us the zone and marking you need so we can confirm the model and send its explosion-protection certificate.
