Opis izdelka
The DP-4000 differential pressure transmitter is an advanced solution for accurate differential pressure and flow measurement in industrial applications. The device features a compact and robust all-stainless-steel housing and is designed for reliable operation with gases, steam, and liquids across a wide range of industries.
Using integrated microprocessor technology, the DP-4000 can be easily configured through a unique programming button and graphical display. The transmitter is especially suitable for precise flow measurement applications where differential pressure across an orifice plate, Venturi tube, or Pitot tube is converted into flow rate using the built-in square root function.
The transmitter includes a multilingual display with backlight and bar graph for clear local process indication. Optional intrinsically safe versions are available with ATEX and IECEx Ex ia IIC T6 Ga certifications, making the device suitable for hazardous environments.
With its high accuracy, flexible configuration options, and durable stainless-steel construction, the DP-4000 is ideal for demanding industrial flow and pressure monitoring applications.
Tehnične specifikacije
The DP-4000 offers a measuring range from 10 mbar up to 20 bar and supports static pressures up to 160 bar, with an optional version rated up to 250 bar. The process temperature range is -20 °C to +100 °C.
Measurement accuracy is specified at 0.075%, with an optional high-accuracy version available at 0.065%. The transmitter supports a turndown ratio of up to 100:1 for flexible process applications.
Standard process connections are 1/4"-18 NPT female, with optional 1/2" NPT connections available. Output signals include 4–20 mA two-wire with HART protocol version 7.0 and optional Profibus PA communication.
Configuration can be performed directly via the integrated programming button and display, without requiring test pressure equipment, or alternatively through HART communication.
The multilingual display includes a bar graph, backlight, and process temperature indication for enhanced local monitoring.
Power supply requirements are 12–36 VDC, or 12–30 VDC for explosion-proof versions. Protection class is IP66, with optional IP68 protection available. Ambient operating temperature ranges from -20 °C to +70 °C.
The diaphragm material is AISI 316L stainless steel, with optional materials including Hastelloy C, Tantalum, or gold-plated diaphragms. Wetted parts are manufactured from AISI 316L, with optional Hastelloy C versions available.
The standard sensor gasket material is Viton, with optional PTFE or NBR seals. The electronics housing is made from AISI 304 stainless steel, with an optional AISI 316 version available.
Optional certifications include ATEX Ex-ia and IECEx Ex-ia explosion protection approvals, including optional T5 and T6 classifications.
Available accessories include 3-way and 5-way manifolds from Klay Instruments.
