Product Overview
DEIF XL‑144 is marine‑grade back‑lit analog panel indicator from X‑Line series, built on patented X‑coil micro‑processor movementDEIF. Mainly used on ship bridge and engine‑room consoles for main‑engine RPM (astern‑0‑ahead bidirectional), rudder angle, propeller pitch, genset speed. Interchangeable dial scales support custom measuring ranges. White back‑light with dimming input adapts day‑night bridge operation. Widely used for new‑build vessels and spare‑part replacement of old marine consoles.
Two major hardware variants:
- Analog input version (4‑20 mA / ±10 V DC)
- CANopen / Scan‑bus digital communication version
Application Scenarios
- Ship bridge console: Bidirectional main‑engine RPM, rudder‑angle, propeller‑pitch indication for cargo‑ships, workboats, offshore vessels
- Engine‑room switchboard: Genset speed, voltage, current local indication
- Off‑shore platform auxiliary machinery monitoring
- Diesel engine test‑bench speed indication
- Legacy marine system retrofit & spare‑part replacement: same cut‑out size, direct drop‑in replacement, minimal console modification
