F01 SAFETY
Pressure switch
The Pressure Switch F01 fulfils the high requirements of the EN13849-1 Machinery Directive. This pressure switch can be used for systems with Performance Level PL d and therefore for safety-critical applications. The F01 possesses an E1 approval and can be used up to a maximum media temperature of +125 °C.
TECHNOLOGIES
The F01 is available for pressure ranges from 10 bar to 1000 bar and has two switching outputs which switch inverted to each other. Optionally, the F01 is also available in a version with one switching and one analog output. Here, the current output is read back by the F01 to ensure that the output signal is emitted correctly. To be able to use the F01 in as many applications as possible, users can select different pressure connections. The electrical contact takes place via a 5-pole M12 connector. Through the calibration of the transmitter via the temperature, a total accuracy of 1 % FS can be achieved within a range of 0…80 °C. The maximum media temperature totals +125 °C. The stainless steel parts coming into contact with media guarantee maximum media compatibility in combination with the welded thin-film measurement cell.
