Product Overview

The Graco 235009 Airless Sprayer Transducer is a mechanical pressure transducer that senses fluid pressure and sends a signal to the sprayer’s control system to maintain consistent PSI and spray quality.

Part Number 235009
Type Mechanical pressure transducer (airless systems)
Primary Function Monitors system pressure and relays it to the control electronics for stable spray output.
Typical Use Replacement sensor for compatible Graco ST / STS / Duron / Nova / GM 3000 / LineLazer models (see list above).

Key Benefits

  • Helps the sprayer hold a steady pressure for uniform finish.
  • Protects equipment by allowing the controller to react to over-/under-pressure conditions.
  • Direct replacement for numerous legacy Graco models for quick repairs and minimal downtime.

Install & Compatibility Notes

  • Confirm your exact model/serial and the transducer’s thread/connector match before ordering.
  • Relieve pressure, power off, and follow the service manual when replacing the sensor.
  • After installation, test at low pressure first and check for leaks or error codes.

Frequently Asked Questions
