The differential pressure generated by the primary element is transformed into an electrical 4-20 mA signal proportional to the flow rate by the differential pressure. The DP-4000 differential pressure transmitter from Klay Instruments has a square root function with adjustable cut off point for flow measurement.
The DP-4000 is standard equipped with a compact and rugged Stainless Steel electronics housing. This unique feature makes it very suitable for the food & dairy-, (petro)chemical and offshore industry. It has a basic accuracy of 0.075% (Option: 0.065%). Ranges are available from 10 mbar to 20 bar with a turn down up to 100:1.
Programming can be done very easy without test pressure by using the unique ‘One Touch programming button’ together with the graphic display with backlight. The multilingual graphic display can indicate a number of chosen engineering units and the actual value in a bargraph. Damping times can be adjusted and a 4-20 mA current simulation can be performed. Various remote ‘chemical’ seals are available. The diaphragm material is standard SS316L, as an option Hastelloy C or Tantalum can be supplied. The output is 4-20 mA including HART protocol.
For use in hazardous environments the DP-4000 is certified according to both ATEX II1G (Ex ia IIC T6) and IECEx.
