Titan part 0551112 is a Pressure Transducer Assembly used in the electronic control systems of compatible sprayers. This sensor measures the fluid pressure inside the sprayer's pump or manifold and converts it into an electronic signal for the control board. It is a critical component for sprayers with digital pressure displays, automated pressure control, or diagnostic systems.

The Titan 0551112 is a genuine OEM Pressure Transducer Assembly. This electronic sensor is threaded into the high-pressure fluid system of the sprayer. Its internal diaphragm and circuitry convert the physical fluid pressure into a proportional electrical signal (often a voltage or current) that is sent to the machine's main control board or digital display unit.
A faulty pressure transducer is a common cause of electronic control system failures. Symptoms include an inaccurate or flickering pressure display on the screen, the inability to set or maintain pressure electronically, or the sprayer shutting down and displaying a pressure-related error code. Replacing it with the correct Titan 0551112 assembly restores accurate pressure sensing and reliable operation of the electronic control features.
| Pressure Sensing | Measures the real-time fluid pressure within the sprayer's pump or manifold. |
|---|---|
| Signal Conversion | Converts the physical pressure reading into an electronic signal the control board can read. |
| System Feedback | Provides critical data for closed-loop pressure control, digital display readouts, and system diagnostics. |
| Inaccurate Pressure Readout | The digital display shows incorrect pressure, zero pressure, or the reading fluctuates wildly. |
|---|---|
| Control System Failure | The sprayer cannot maintain set pressure, enters a default mode, or displays an error code related to pressure sensing. |
| Physical Damage | The sensor body is cracked, its electrical connector is damaged, or there are signs of fluid ingress. |
| Diagnostic Confirmation | Electrical testing (per the service manual) confirms the transducer is out of specification or has failed. |
The Titan 0551112 Pressure Transducer Assembly is used across a broad family of sprayers that feature electronic pressure control and monitoring. It is compatible with the following models and series:
| Compatible Sprayer Series / Platform | Specific Compatible Models |
|---|---|
| Titan Advantage Series | Advantage 400, Advantage 500, Advantage GPX 85 |
| Titan Impact Series | Impact 410 |
| Titan Powerliner / PowrLiner Series | PowrLiner 2850 GB_D_F, PowrLiner 1800M, PowrLiner 2800M |
| Titan Rental Series | RentSpray 400 |
| SprayTech Airless Series | SprayTech Airless Advantage EPX2155, EPX2255 SprayTech Airless EPX2155, EPX2255 SprayTech GPX 85 |
This transducer's wide compatibility indicates it is a standard electronic sensor for a universal control system used across Titan's professional and retail sprayer lines.
When diagnosing or replacing the pressure transducer, these related electronic components and connections should be inspected.
The circuit board that receives the signal from the transducer. It should be checked for burnt components or poor connections.
The wiring that connects the transducer to the control board. Look for damaged wires, corrosion, or loose pins in the connectors.
The user interface screen that shows the pressure reading. It can fail independently of the transducer.
A small O-ring or seal where the transducer threads into the manifold. This must be replaced to prevent fluid leaks.
