Q: What is the sensing technology used in the design of the OPS3 Oil Quality Sensor?
A: The oil quality sensor uses a tuning fork technology, a piezoelectric resonator, that vibrates when a high frequency current is applied. The vibration creates, in response, an impedance that the sensor electronics can measure.
Q: What are the measurement ranges for the OPS3 sensor?
A: The sensor can measure in the following ranges:
- Dynamic viscosity: 0.5 to 50cP (centipoise)
- Density: 0.65 to 1.5g/cm3 (kg/m3)
- Dielectric constant: 1 to 6
- Resistance: 1.0E+06 to 1.0 E+08Ω
- Temperature: -40°C to +150°C
Q: What are the available power supply options?
A: The OPS3 Oil Quality Sensor is compatible with 12V or 24V power supply; the OPS3 will function properly for voltages ranging from 9V to 36V. The associated maximum current will not exceed 100mA.
Q: What is the communication protocol for the sensor?
A: The OPS3 Oil Quality Sensor provides a CAN output based on SAE J1939 standard.
Q: What is the preferred mounting area for the OPS3 sensor?
A: The sensor should be installed in a pressurized area on the clean side of the system (after the filter). Dead ends and oil pans should be avoided, and some minimal oil flow is preferred to ensure temperature homogeneity.
Q: How can the OPS3 Oil Quality Sensor help me to determine when an oil change is required?
A: Based on OPS3 outputs, the user can develop algorithm(s) that best suit their system/application and lubricant type.
