NOx Sensör Caffini NOx Sensor Emulator | Farm Machinery SCR Fix
Plug-in NOx sensor emulator for Caffini agricultural machinery that simulates upstream and downstream sensor signals, keeping the machine running at full power in the field.
Caffini sprayers and pulverisers are built for continuous, high-intensity work across vineyards, orchards and arable land — and there is no room for unplanned downtime in the middle of a spray window. The SCR system's NOx sensors are under constant stress from dust, soot and high exhaust temperatures, and when one fails the machine triggers a fault lamp, raises an AdBlue (DEF) alert and throttles into limp mode, bringing fieldwork to a halt at the worst possible moment. Genuine NOx sensors are expensive items with long supply lead times. The Caffini NOx Sensor Emulator solves this at the electronic level, restoring full performance quickly and cost-effectively.
How Does It Work?
The emulator connects to the machine's NOx sensor connector via the factory socket — no wire cutting, no soldering and no workshop equipment needed. Once active, it continuously delivers the healthy upstream and downstream NOx signal values the control unit expects, along with correct sensor warm-up and ready-state data. Because the ECU receives valid, consistent readings, it generates no NOx sensor fault codes, suppresses no AdBlue warnings and never drops the machine into power-restriction mode.
Frequently Asked Questions
Which Caffini machines is this emulator compatible with?
It is compatible with Caffini sprayers and agricultural machines equipped with SCR and NOx sensor systems. Please confirm your machine's engine and ECU details with us before ordering to ensure compatibility.
Do I still need to replace the original NOx sensor?
No. The emulator replicates the signals the faulty sensor would send to the ECU, so the machine runs normally without a costly genuine sensor replacement.
How long does installation take and is it reversible?
Installation is plug-and-play — the device attaches to the existing sensor connector with no wire cutting or soldering. Removing it returns the machine to its original factory configuration with no permanent modification.
Is there a legal notice I should be aware of?
This product is designed for off-road and closed-site use. Compliance with applicable emissions regulations is the sole responsibility of the user.
