DPR-2000 SMART Differential Pressure Transmitter

Brand: Delta Mobrey
Request Information
Favorite

The model DPR-2000 Differential Pressure Transmitter is suitable for measuring pressures from -100 mbar to 70 bar with maximum working pressures up to 420 bar. 

The DPR-2000 SMART Differential Pressure Transmitters are suitable for measuring differential pressure of gases, vapours and liquids. 

The active sensing element is a piezoresistive silicon sensor separated from the medium by a diaphragm and by a specially selected type of manometric liquid. The special design of the active sensing element ensures that it is able to withstand pressure surges and overloads of up to 250/320/420 bar. 

The casing is made of cast Aluminum alloy or 316 stainless steel with degree of protection IP66/IP67. The design of the casing enables the use of a local display, rotation of the display by 90°, rotation of the casing by 0 to 355° relative to the sensor, and a choice of cable direction.
