The filter value determines the dynamic behaviour of the indicated value high values mean a slow display with smoother response The filter is disabled if a filter value of 1 is selected In other words the indicated value is equal to the unfiltered measured value no dampening occurs The integrated step detector responds to a measured value step change greater than approximately 6 25 of the upper range value When a measured value step change is detected the actual measured value is displayed immediately 11 3 Start adjustment The zero point can be recalibrated when the sensor is in the unpressurized state As a security precaution the operator must hold the 4 key pressed for 7 seconds before he can activate Value setting menu item S A 11 4 Change Code Change code CCo protects the device against unauthorized changing of the set device parameters by allowing the operator to enter a secret code If the code set is different to 000 then the operator must enter the set code before entering the set up mode PDA 12 02 page 9 PDA 12 Technical Information Case cover Connections Gasket Principle of measurement Display Resolution Max temperature Overpressure Supply Power consumption Electrical connection Output Load Settings Overrange underflow indication Measuring cycle Accuracy Protection type page 10 stainless steel 1 4305 G 1 4 or G 1 2 male thread stainles
3. amp Safety and prevention of accidents 3 Regulation use Pressure transmitters are used to measure pressure in vessels hydraulic and pneumatic plant refrigeration equipment and so forth Any use of the pressure transmitter PDA which exceeds the manufacturers specification will invalidate the warranty and any resultant damage is therefore not the responsibility of the manufacturer The user assumes all risk for such usage 4 Operating Principle The KOBOLD pressure transmitters model PDA are electronic measuring instruments with a digital display of the system pressure There is an output signal 0 4 20 mA for transmission The sensor element is a piezoresistive ceramic cell The PDA is used wherever exact pressure measurements with compact local display is required The PDA is perfect for industrial use because of its high long term stability save reproducibility and its small robust package PDA 12 02 page 3 PDA 5 Instrument Inspection Instruments are checked before shipping and should arrive in perfect condition In case of damage please inform your local Kobold office or your parcel forwarding agent immediately since they are responsible for damages during transit Should the damage to a device be visible we recommend a thorough inspection of the delivery packing Scope of delivery e Pressure transmitter PDA e Operating Instructions 6 Mechanical connection Pressure taps should be prepared
