Operating Principle
The operation of a 1/8 NPT oil pressure sensor can be described in the following steps:
- The sensor is installed into the oil system of an engine or machine.
- As the oil circulates, it exerts pressure against the sensor’s diaphragm.
- This pressure causes the diaphragm to flex—a small amount of movement that correlates with oil pressure.
- The transducer converts the diaphragm’s movement into an electrical signal proportional to the pressure detected.
- The electrical signal is then transmitted to the engine control unit (ECU) or a gauge, providing real-time data on oil pressure levels.
Importance of Accurate Readings
The accuracy of a 1/8 NPT oil pressure sensor is imperative for the following reasons:
- It ensures that the engine operates within safe pressure limits.
