The Speed Sensor Tester (SST) is a diagnostic tool used for testing and verifying the performance of speed sensors, which are employed to measure rotational speed in machines, vehicles, and other devices. These sensors are used in automotive systems (e.g., wheel speed sensors, engine speed sensors) and industrial machinery (e.g., tachometers, flow meters).

These sensors are used in automotive systems (e.g., wheel speed sensors, engine speed sensors) and industrial machinery (e.g., tachometers, flow meters).
Typical SST Functions:
- Checking Sensor Output: The tester measures the electrical signal from the speed sensor and checks if it falls within an acceptable range, ensuring proper functionality.
- Simulating Speed Signals: Some testers can simulate a speed signal to check if the sensor responds correctly.
- Verifying Sensor Operation: The tester can detect whether the sensor is operating correctly or if there are any malfunctions or incorrect readings.
- Reading Diagnostic Trouble Codes (DTCs): Advanced SST models can communicate with the vehicle or machine’s diagnostic system, allowing the reading and clearing of fault codes related to speed sensors.
Typical Applications:
- Automotive Industry: Testing wheel speed sensors, ABS (Anti-lock Braking System) speed sensors, and engine speed sensors.
- Industrial Equipment: Verifying tachometers or other speed sensors in machines like motors, pumps, and conveyors.
- Motorcycle/Car Service: Diagnosing issues with cruise control systems, transmission speed sensors, or gear position sensors.
How It Works:
- Connecting the Tester: The SST is connected to the sensor, usually directly to the sensor wires or via a test cable.
- Reading the Signal: The tester displays the electrical signal from the sensor, which may be analog or digital, depending on the sensor type.
- Comparing Values: The tester compares the measured signal with reference values for the specific sensor type. A properly functioning sensor should show a stable and correct signal, while a faulty one may either not produce a signal or generate incorrect readings.
Typical SST Features:
- LCD Display: Used for displaying sensor data or status.
- Adjustable Settings: Allow testing of different sensor types and ranges.
- Durability: SSTs are typically rugged and designed for fieldwork, often with weather-resistant enclosures.
