Differential Pressure Transducer with dual Programmable Current Outputs
The DST 2000 is a smart pressure converter with two pressure inlets and two analogue current outputs. The signal received from its pressure sensors is digitally processed and corrected for sensor temperature dependency and nonliarity. Thus calculated values are displayed and transfered to the 4-20mA analogue current output. The preferred display mode, of either one or the periodical alternation of all values, as well as the current output allocation can both be preprogrammed prior to measuring. The pressure ranges and lowest value for each output can also be changed if necessary.
The DST 2000 pressure converter is typically used for measuring of differential pressures at junction exchange stations. For instance, while one of the outputs is set as a differential pressure outlet (e.g. at 500 kPa) , the other output can measure static pressures P1 or P2, or their average. In order to select the pressure range required, it is important to consider the maximal static pressures in each output.
Allocation of measured values to individual outputs:
* Only when the origin is offset to zero and the programmable range is set to 100%.
DST 2000 functions within an allocated output range of 100 % to 10% of a nominal pressure range. For example, when the pressure is 700 kPa, a pressure difference can be measured from the range of 70 kPa . The maximum overload is then 200% of the basic range, which in this case is 1,4MPa .
DST 2000 allows for a shift of up to +/- 20 % of the nominal range of pressure. For example, for a nominal pressure range of 500 kPa , the output can be shifted by +/-100 kPa .
