GOOD TO KNOW
What you should consider when selecting, installing and operating sensors and switches in hydraulic systems.
Redundancy in the equipment of systems
Faults or failures can occur in any electronic system. For this reason, it is sensible in certain cases to fit more than one switch in a hydraulic system. With redundancy built into the design of the control electronics, your system is reliably protected against switching faults should a switch fail. In addition, the fact that two measurements are taken gives a second value for comparison purposes. This also allows a failing switch to be detected. Safety can be further increased by adding an additional, purely visual display.
Choosing the right sensor
The choice of sensors depends on the installation situation, medium properties and ambient conditions. The application also determines the requirements in accordance with the relevant standards with respect to temperature resistance, IP type and shock and vibration load strength. You should consider the following when selecting your sensor:
- Measurement accuracy, measurement range, measured quantity and output signal strength
- Electrical and hydraulic connections
- Integration into machine and system controls
Prevent wear
Like all other system components, sensors are not 100 % protected from wear. However, you can considerably extend the service life of sensors by following a few simple rules:
- Do not exceed the specified measuring ranges.
- Do not use sensors in media for which they were not designed.
- Ensure the materials they are made from are suitable for the conditions of use.
- Operate the sensors with the correct electrical connections and parameters.
- Avoid overtemperature, shock and vibrations.
