4 Rev. 1.8 Operating Manual for Pressure Sensors 97PA-21x-xxx page 4 of 6 1 Product Description The 97PA-21x-xxx Pressure Sensors were designed for detecting pressures and converting them into electrical signals. They can be installed in any position. All parts coming in contact with the medium are made of stainless steel. A VITON O-ring seal is used for sealing purposes. All 97PA-21G-xxx Pressure Sensors are delivered with a connecting cable of 2.0 m length. 2 Technical Data Article Number 97PA-21G PA-21G PA- 21Y-5 97PA-21Y PA-21Y- 160 Connecting thread [mm] G 1/8 AG G 1/4 AG 97PA-21Y- 400 Operating pressure [bar] max. 10 max. 50 max. 5 max. 25 max. 160 max. 400 Operating temperature [ C] -10 to +80 Outlet signal [ma] 4 to 20 Weight [g] ca. 30 ca. 50 Supply voltage [V] 8 to 28 8 to 32 Pin assignment Areas of application Cable Precision Linearity (best straight) Overall error band C C White out/ground Brown 24 VDC For pressure monitoring on spray, pulse or dosing valves Not suitable for drag chains typ. ±0.25 %FS max. ±0,5 %FS max. ±1.0 %FS max. ±1.5 %FS Load resistance / < (U-8 V) / 0,025 A Load change / > 10 million, %FS at 25 C Limit frequency / 2 khz Response time (supply ON) / (0 99 %) < 5 ms Materials with medium contact Stainless steel AISI 316L (DIN /1.4435) Viton external gasket ( C, no inner gaskets) Oil filling / Silicone oil

Make sure that all sealing surfaces at the measuring location are clean and without damages before the installation. 2. The Viton - gasket (see figure 1) and the gasket ring, article number F (see figure 2) have to be mounted before the actual installation. Fig.1 3. The Pressure Sensor will be glued in with Loctite Only use suitable tools (see figure 1) to screw the device straight into or out of the thread. 5. After that continue with the electrical connection. Take care to connect the cables as described herein (see figure 3). Fig.2 6. Make sure that no humidity can penetrate through the lines. 7. The pressure sensor is now ready for use. Fig. 3 Electrical connections: White: out / ground Brown: 24 V CAUTION The cable of the pressure sensor is not suitable for drag chains. This can damage the pressure sensor.
