What is the approach you used, and what do you suggest, for testing how long of an extension cable (m12 five pin shielded) for the PR55-45L sensor will work reliably? What metrics did you test for/measure or do you suggest one measures and tests for?
The primary unit contains a CPU, and the probe tip is equipped with a sensor. If there are any communication issues, the microcontroller unit (MCU) will fail to receive a response from the sensor, signaling an error. If you consistently receive accurate readings throughout a 24-hour test without missing any data, this indicates that the system is functioning correctly.
