  • Page 4: Instrument Inspection

    PSR/PSE 3. Instrument Inspection Instruments are inspected before shipping and sent out in perfect condition. Should the damage to a device be visible, we recommend a thorough inspection of the delivery packing. In case of damage, please inform your parcel service/ forwarding agent immediately, since they are responsible for damages during transit.

  • Page 5: Operating Principle

    PSR/PSE 5. Operating Principle The KOBOLD flow monitors of series PSE and PSR are used where economical, reliable flow monitors are indicated. Depending on the flow velocity respectively flow rate, the baffle plate is deflected and moves the permanent magnet via the balance arm into the switching range of the reed contact mounted outside of the flow media.

    PSR/PSE 6.5. Electro-Static The devices are to be protected against electrostatic unloading. The case of the device is to be earthed electro-statically (for example with metal pipes). Besides, the local potential balance is to be established according to local regulations. The wires must be protected in the installation in the hazardous area “0”...

  • Page 8: Mechanical Connection

    PSR/PSE 7. Mechanical Connection Before installation  Please check that the actual flow matches with the switching range of the instrument.  Ensure that the allowable maximum operating pressure and operating temperature of the instruments will not be exceeded.  Remove all transport packing and be sure that no packing material is left in the instrument.

  • Page 9: Electrical Connection

    PSR/PSE 8. Electrical Connection  Ensure that the electrical supply lines are powerless.  Connect the connection cable with your supply cable.  The contact housing is made of glass-fibre reinforced plastic. It is insulated in accordance with VDI 0720 Class II; separate insulation measures are not necessary.
  • Page 10 PSR/PSE Switch Point Adjustment When adjusting the switch point, the clamp plate in the top of the upper housing must be loosened, enabling the switching unit to be repositioned. For ease of adjustment, the switching unit is marked with a white and a red arrow. The front edge of the clamp plate serves as the adjustment marker.

  • Page 11: Maintenance

    PSR/PSE Contact protection The reed contact may be damaged if the switch ratings are exceeded, especially while switching inductive or capacitive loads. This can cause unsafe conditions. By using a contact protection/isolation relay (e.g.: Model MSR 10), this problem can be overcome and the lifespan and switch rating of the reed contact can be extensively increased.
