   Description
    With its 4 ... 20 mA, 4 ... 20 mA HART®, PROFIBUS® PAor FOUNDATION Fieldbus™ output signals, combined with either intrinsically-safe or flameproof ignition protection （in accordance with ATEX）, the DPT-10 is ideally suited to applications requiring these features. The electronics of all of these transmitters, even for the flameproof variant, are intrinsically safe. Thus it is possible to make adjustments on the instrument in EX areas while the instrument is live.

   Versatile in application
    The DPT-10 is suitable for many industrial measuring requirements, such as flow measurement using differential pressure transducers, level measurement or filter and pump monitoring.
    With diaphragm seals fitted, the DPT-10 is also suitable for harsh process conditions. As a result of the available measuring ranges of 0 ... 10 mbar up to 0 ... 40 bar and a static pressure limitation of up to 420 bar, the instrument can be used in almost any application. The internal digital signal processing, combined with proven sensors, guarantees high accuracy and the best long-term stability.

    There are seven different housing variants available, and thus, it is possible to select a variant suited to every operating environment. The housing itself can be rotated through 330°, and is available in plastic, aluminium and stainless steel. An electropolished stainless steel housing （316 L） is available to meet the high demands of the food industry and pharmaceutical industry.

    Easy configuration and operation Service and configuration at the instrument is carried out using the optional display and operation module, which can be fitted in four positions. The operation menu has a simple and self-explanatory structure and has seven selectable languages as standard. Alternatively, the operating parameters can be set using the PACTware™ free and non-proprietary configuration software. An instrument-specific DTM enables easy integration into a corresponding Distributed
Control Systems.

    With upstream pressure equalising valves it is possible to avoid unilateral overpressure loadings during both start-up and operation as well as enabling zero point checks during operation. Furthermore, they enable the isolation of the process lines without interference to the running process.
    These pressure equalising valves with integrated shut-off valves, and also purge and ventilating valves, in addition enable the venting of the pressure gauge on one or both sides and enable the supply line to be purged.

   

    Model DPT-10 differential pressure transmitters can be adapted to the harshest conditions in the process industry by using diaphragm or diaphragm in-line seals. Thus, the transmitters can be used at extreme temperatures, and with aggressive, corrosive, heterogeneous, abrasive, highly viscous or toxic media. As a result of the wide variety of aseptic connections （such as clamp, threaded pipe or DIN 11 864 aseptic connections） measuring assemblies meet the high demands of sterile
process engineering.
    Differential pressure transducers for flow measurement are available as accessories. Depending on the application, the differential pressure transducers are designed as simple push plugs, measuring flange or complete measuring path.
