Measuring pressure, level, and temperature for hydraulic and cooling lubricant systems

Several parameters must be monitored on CNC machines: the oil and cooling lubricant levels, the locking positions or forces of the workpiece clamps, and the permissible operating temperatures of the oils or cutting fluids. The PBS Plus pressure switch supplies digital and/or analog signals to the controller for monitoring pressure. Thanks to the IO-Link interface sensors that are difficult to access can be configured easily via remote access and the pressure values displayed on the machine's HMI. Limit values in the chip conveyor are safely detected using an LFV200 vibrating level switch. The LFP Cubic offers four switching points in one sensor, thus reducing mechanical complexity and the costs of the individual sensors that would otherwise be required. The TBS temperature sensor reliably monitors operating temperatures.
