Pneumatic, hydraulic and vacuum system monitoring
Balluff's pressure sensors measure a variety of pressures, such as hydraulic or pneumatic systems for machine movement, as well as liquids, viscous media and gases for other processes. These sensors are available with integral displays that also provide a programming means and diagnostics window into the sensor or as an instrument only device with no display. Pressure sensors connected to networks such as IO-Link can provide improved process flexibility and control through enhanced sensor monitoring, parameterization, and error reporting back through the system controller.
Balluff's pressure sensors incorporate output switching functionality as well as visual display of the current pressure. Since these devices are electronic, there is a multitude of output characteristics available including discrete on/off outputs and continuous analog output proportional to the pressure value.
Balluff's flush-mounted sensors are the perfect solution when sensing pressures of media that is thick, sticky or liquids with suspended solids. These sensors are free of dead space which prevents unwanted particles from blocking the sensing orifice.
Balluff pressure sensors incorporate output switching functionality as well as visual display of the current pressure. Since these devices are electronic, there is a multitude of output characteristics available as opposed to the simple on-off functionality of the classic mechanical pressure switch. These include multiple discrete PNP or NPN outputs from one sensor with programmable functionality. In many cases, a sensor will provide a single discrete set point output and a continuous analog output proportional to the pressure value. The discrete output can provide an alarm function while the analog output provides a dynamic value of the process.
Balluff's pressure sensor display is multifunctional. Not only does it display dynamic values, it is also used for programming or configuring the sensor. The display includes: pressure value, parameters, parameter values, and output status, as well as programming keys and keypad lock-out functionality to prevent unauthorized tampering.
Pressure transducers or transmitters are perfect for applications that requires only an analog feedback without display or the display will not fit due to mounting and space limitations. Balluff's pressure transmitters are compact in size and have stainless steel housings for harsh environments.
Balluff's pressure transmitters are compact and can be located in space-restricted areas. There is a process connection and an electrical connection. The sensor is selected for the pressure requirements and the analog output operates across that entire range, for instance a 0-145 PSI pressure range would output 0-10V. Current-output versions 4-20mA are more commonly used in industrial applications as the wiring lengths can be longer and are not affected by electrical noise unlike voltage outputs.
Pressure sensors connected to factory networks through sensor-level communications protocols such as IO-Link can provide improved process flexibility and control through enhanced sensor monitoring, configuration, and error reporting back through the system controller. Digital transmission of analog values over low-cost, unshielded four-wire cabling ensures high signal quality over longer distances and eliminates signal delays and distortions that sometimes plague analog interfaces.
Networkable sensors reduce downtime and configuration errors with plug-and-play functionality. Maximum system flexibility can be achieved during operation as parameters can be modified quickly and remotely through the control system rather than at the physical sensor itself. In addition, process diagnostics, data, and errors can be reported directly to the controller and displayed on man-machine interfaces.
