The MPU Perkins MSP679 is a magnetic speed pickup sensor (MPU) designed to accurately detect engine rotational speed by sensing ferrous gear teeth movement. It generates a reliable electrical frequency signal that is used by generator and engine control systems to monitor and regulate speed for stable performance.
Where It Is Used
The MPU MSP679 is widely used in:
-
Generator engine control systems for speed sensing
-
Diesel engines with electronic governor controls
-
Industrial and power generation equipment requiring precise RPM feedback
-
Controllers such as GAC electronic speed regulators that depend on accurate speed input signals
Key Functions
-
Speed detection: Produces an electrical signal proportional to engine speed
-
Magnetic pickup design: Detects gear rotation without external power
-
Signal delivery to governor/control unit: Enables stable engine speed regulation
-
Durable construction: Stainless or protected housing for harsh environments
-
Threaded mounting: Standard 5/8-18 UNF install for easy replacement
