Final answer:
Possible indications of an oil pressure transmitter or indicator malfunction include inaccurate readings, zero pressure readings, and erratic readings.
Step-by-step explanation:
A malfunctioning oil pressure transmitter or indicator in a machinery system can have several indications:
- Inaccurate readings: The oil pressure readings displayed on the indicator may be significantly different from the actual pressure in the system. This can be due to sensor calibration errors or damage to the electrical circuit that transmits the pressure data.
- Zero pressure readings: If the oil pressure indicator consistently shows zero pressure, it could be a sign of a malfunctioning transmitter. This can indicate that the sensor is not detecting any pressure in the system or that there is a problem with the connection between the transmitter and the indicator.
- Erratic readings: A malfunctioning transmitter may give inconsistent or fluctuating oil pressure readings. This can be a result of faulty sensor components, such as a faulty pressure sensor or issues with the electrical connections.
