Main Features and Advantages
Dual Functionality:Speed&Position Detection in One Unit:The Woodward XI1S5 eliminates the need for separate speed and position sensors by combining both functions in a single module.This not only reduces equipment costs and cabinet space but also simplifies wiring and synchronization between the two types of data.For example,in a gas turbine application,Woodward XI1S5 detects both the turbine’s RPM(to maintain optimal operating speed)and the shaft’s angular position(to coordinate fuel injection timing).This integration ensures that speed and position data are time-aligned,preventing delays that could cause fuel inefficiencies or turbine wear—an advantage that separate sensors,which often have mismatched response times,cannot match.
Rugged Design for Harsh Environments:Industrial power equipment operates in some of the toughest conditions—from the high vibration of marine diesel engines to the extreme temperatures of power plant turbine halls.Woodward XI1S5 is built to withstand these challenges:its aluminum alloy housing(IP66 rated)resists corrosion and dust ingress,while its-40℃~85℃operating range handles frigid arctic marine environments and hot desert power plants alike.It also meets military-grade vibration(20g)and shock(100g)standards,ensuring it remains functional even during equipment startup or transient events.A case study from a offshore oil rig showed that Woodward XI1S5 operated reliably for 5 years in a saltwater,high-vibration environment,while generic sensors needed replacement every 6-12 months.
Multi-Signal Compatibility&Flexible Output:Woodward XI1S5 supports a wide range of input sensors—magnetic pickups(common in older engines),optical encoders(for high-precision applications),and Hall-effect sensors—making it a versatile choice for retrofits or new installations.This means you don’t need to replace existing sensors when upgrading to Woodward control systems;Woodward XI1S5 can adapt to your current setup.On the output side,it offers both analog(4-20mA)and digital(TTL/RS485)signals,allowing seamless integration with Woodward governors,PLCs(Programmable Logic Controllers),or SCADA(Supervisory Control and Data Acquisition)systems.For instance,a power plant using a SCADA system can receive digital speed data via RS485 for real-time monitoring,while the Woodward 505E governor uses the 4-20mA analog signal for closed-loop speed control—all from a single Woodward XI1S5 module.
High Accuracy&Fast Response:In power control,even small speed deviations(e.g.,±0.5%of setpoint)can lead to reduced efficiency or equipment damage.Woodward XI1S5 delivers±0.1%full-scale accuracy,ensuring precise speed detection for critical applications like generator frequency control(where frequency must stay within±0.1Hz of 50/60Hz).Its≤10ms response time also means it quickly detects sudden speed changes—such as a load spike on a generator—and transmits data to the controller,allowing for rapid adjustments(e.g.,increasing fuel supply)to stabilize speed.This fast response is critical for preventing“trips”(emergency shutdowns)that can disrupt power supply;in a hospital backup generator system,for example,Woodward XI1S5’s quick detection of a speed drop ensures the controller responds in time to avoid a power outage.
Application Field
In Power Generation,Woodward XI1S5 is a cornerstone of generator speed control and synchronization.Whether in coal-fired power plants,natural gas peaker plants,or renewable energy(e.g.,biogas)facilities,generators require precise speed control to maintain 50/60Hz frequency—essential for grid compatibility.Woodward XI1S5 detects the generator’s RPM and transmits data to Woodward 505E governors,which adjust fuel or steam flow to keep speed stable.For example,in a combined-cycle gas turbine(CCGT)plant,Woodward XI1S5 monitors both the gas turbine’s speed(to optimize combustion)and the steam turbine’s shaft position(to synchronize with the generator).Its ATEX/IECEx certification also makes it suitable for hazardous locations,such as oil refinery generator rooms where flammable vapors may be present.Without Woodward XI1S5’s accuracy,generators could experience frequency fluctuations that damage sensitive equipment or cause grid instability.
Within Marine Propulsion Systems,Woodward XI1S5 ensures the reliable operation of diesel or gas turbine engines that power ships and offshore platforms.Marine engines face constant vibration,saltwater corrosion,and temperature swings—but Woodward XI1S5’s rugged design(IP66 housing,MIL-STD vibration resistance)stands up to these challenges.It detects the engine’s RPM and crankshaft position,transmitting data to Woodward marine controllers to adjust fuel injection and throttle position.For instance,in a container ship with twin diesel engines,Woodward XI1S5 modules on each engine provide speed data to the propulsion control system,ensuring both engines run in sync to avoid propeller damage.Its-40℃low-temperature rating also makes it ideal for arctic shipping routes,where generic sensors would fail in freezing conditions.
In Industrial Machinery,Woodward XI1S5 is used to control large engines and turbines in manufacturing,mining,and construction.For example,in a mining haul truck with a diesel-electric drivetrain,Woodward XI1S5 monitors the diesel engine’s speed to optimize power output and fuel efficiency,preventing overspeeding that could lead to engine failure.In a cement plant,it controls the speed of the kiln drive turbine,ensuring consistent rotation for proper cement curing.Its flexible input compatibility is particularly valuable here—many older industrial machines use magnetic pickups,and Woodward XI1S5 can integrate with these without requiring sensor replacements,saving time and cost during upgrades.The module’s long service life also reduces maintenance downtime,critical for industries that rely on 24/7 operation.

Installation and Maintenance
Pre-installation preparation:First,confirm that Woodward XI1S5 is compatible with your equipment’s sensor type(e.g.,magnetic pickup,optical encoder)and Woodward control system(e.g.,505E).Check the mounting location—ensure it is within 1-2 meters of the rotating shaft(to minimize signal loss)and away from high-heat sources(e.g.,turbine exhaust)that exceed its 85℃operating limit.Inspect the module for physical damage(e.g.,dents in the aluminum housing,bent pins)before installation.Prepare tools like a torque wrench(to secure the flange mount without over-tightening)and a multimeter(to verify input voltage).For hazardous locations,ensure Woodward XI1S5 has the correct ATEX/IECEx certification for your zone.Finally,power off all connected equipment before wiring to prevent electrical damage to Woodward XI1S5 or the controller.
Maintenance recommendations:Conduct quarterly visual inspections of Woodward XI1S5—check the housing for corrosion(especially in marine or coastal environments)and ensure wiring connections are tight(vibration can loosen terminals).Clean the module’s exterior with a dry cloth;avoid water or harsh chemicals that could damage the IP66 seal.Every 6 months,calibrate Woodward XI1S5 using Woodward’s calibration software to maintain its±0.1%accuracy—this is critical for applications like generator frequency control.Test the module’s response time annually using a signal simulator to ensure it detects speed changes within 10ms.If Woodward XI1S5 displays error codes(e.g.,“signal loss”or“overtemperature”),first check the input sensor and wiring before replacing the module.Store spare Woodward XI1S5 modules in a dry,temperature-controlled area(-20℃~60℃)to preserve their calibration and component life.
