Part 800-101 is a replacement transducer assembly used in the pressure monitoring system of compatible airless sprayers. This electronic component converts fluid pressure into an electrical signal for the control board, enabling accurate pressure display and consistent spray performance. When the original transducer fails, pressure readings become erratic or inaccurate, affecting spray quality.

The 800-101 transducer assembly is a direct replacement electronic component for 740 i Airless Sprayer and 740 IX models. This device mounts in the fluid path and continuously monitors system pressure, converting mechanical pressure into an electrical signal sent to the control board. The control board uses this signal to display accurate pressure readings and regulate motor operation for consistent spray output. A failing transducer can cause erratic pressure display, inaccurate readings, or complete loss of pressure monitoring, leading to inconsistent spray patterns and difficulty adjusting pressure. This replacement assembly is manufactured to match original specifications for precise signal output and reliable performance. Installation requires access to the fluid section and proper electrical connection. Regular calibration check helps identify transducer drift before it affects spray quality.
| Pressure monitoring | Continuously measures fluid pressure in system |
|---|---|
| Signal conversion | Converts pressure to electrical signal for control board |
| Display accuracy | Enables precise pressure readout on user interface |
| Erratic readings | Pressure display fluctuates randomly |
|---|---|
| Inaccurate pressure | Display shows wrong pressure vs. actual output |
| No pressure display | Display shows zero regardless of actual pressure |
| Signal failure | No electrical output from transducer |
