DEIF, TRI-2 Rudder Indicator

The DEIF TRI‑2 Panorama Rudder Indicator is a marine bridge instrument used on ships to display the rudder angle (rudder position) to the helmsman or bridge crew. It is typically installed overhead on the bridge so it can be seen easily from different positions. ⚓

What the TRI-2 Rudder Indicator Does

Shows real-time rudder angle (port or starboard) based on the signal from a rudder angle transmitter.
Helps the operator monitor how much the rudder is turned while steering.
Used in ship steering systems and navigation bridges.
