Function and features The pressure sensor detects the system pressure and converts it into an analog output signal (4 ... 20 mA). The measuring range can be scaled to up to 25% of the value of the span (→ page 19, 21). It is also indicated: •...
Use with factory setting Installation Before mounting and removing the sensor, make sure that no pressure is applied to the system. The unit is adaptable for various process fittings. ifm adapters to be ordered separately as acces- sories. Mount adapter (C) to the sensor (A) first, then sensor + adapter to the process connection by means of a nut, a clamping flange or...
Use with factory setting Step 2 Screw the sensor into the adapter. Avoid mechanical influ- ence on the sealing chamfers. Step 3 Clamp sensor and adapter into a clamping device (E). The sealing chamfers (F) must not be dam- aged. Tighten the sensor with a spanner until you can feel the end stop.
Use with factory setting Installation and set-up / operation / maintenance After mounting, wiring and setting check whether the unit operates correctly. Cleaning of the filter cover If viscous and residues producing media clog the filter cover of the sensor (and thus reduce the mea- suring accuracy slightly), you can clean it.
Programming / Use with EPS RS232 interface EPS RS232 interface Connect the sensor to a PC via the EPS-RS232 interface (order no. E30066). • The sensor is supplied with operating voltage by the interface, • and transmits its data (measured values, analogue signal and para- meter settings) continuously via the interface.
3 Programming / Use with EPS RS232 interface Wiring of sensor and EPS interface For use of the sensor with EPS interface prior to installation of the sen- sor: Use a suitable power supply (24 V power supply; ifm order no. E30067).
