Some key functions of an Oil Pressure Transmitter in a cotton picker include:

1. Monitoring engine oil pressure: The transmitter can measure the oil pressure within the engine of the cotton picker to ensure that it is operating within the recommended pressure range. Low oil pressure can indicate potential issues with the engine that need to be addressed promptly to prevent damage or malfunction.

2. Monitoring hydraulic system oil pressure: The transmitter can also monitor the oil pressure in the hydraulic system of the cotton picker, which is critical for the operation of various hydraulic components such as the picker head, lift system, or drive system. Proper oil pressure is essential for the efficient and safe operation of these hydraulic systems.

3. Sending alerts and warnings: The Oil Pressure Transmitter can send alerts or warnings to the operator or the control system of the cotton picker if the oil pressure deviates from the preset levels, helping to prevent potential damage to the engine or hydraulic system.
