ĐỒNG HỒ ĐO ÁP SUẤT WIKA DPGT43HP.100, DPGT43HP.160

Applications
* Acquisition and indication of processes
* Output signals 4 ... 20 mA, 0 ... 20 mA, 0 ... 10 V for the transmission of process values to the control room
* For measuring locations with a high differential pressure overload and/or high operating pressures (static pressures), also in aggressive environments
* Easy-to-read, analogue on-site indication needing no auxiliary power
Special Features
* High operating pressure (static pressure) and high overload safety, selectable up to 40, 100, 250, 400 or 650 bar
* Measuring cell liquid damping against rapid pressure changes
* No configuration necessary due to “plug-and-play”
* QR code on dial links to instrument-specific information
* Individual, non-linear characteristic curves (e.g. x2 or √x for flow measurement)
Description
Wherever the differential pressure must be indicated on site and, at the same time, a signal transmission to the central control or control room is desired, the model DPGT43HP intelliGAUGE® (patent, property right: e.g. DE 202007019025) can be used.
The model DPGT43HP is based upon a model 732.14 high-quality, stainless steel pressure gauge with a nominal size of 100 or 160. The pressure measuring instrument is manufactured in accordance with EN 837-3.
The use of high-quality stainless steel materials and the robust design are geared to applications in the chemical and process engineering industries. Thus the instrument is suitable for liquid and gaseous media, also in aggressive environments.
A high overload safety is achieved by the all-metal construction and the close-fitting design of the measuring element.
The robust diaphragm measuring system produces a pointer rotation proportional to the pressure. An electronic angle encoder, proven in safety-critical automotive applications, determines the position of the pointer shaft – it is a non-contact sensor and therefore completely free from wear and friction. From this, the electrical output signal, proportional to the pressure, of 4 ... 20 mA, is produced. The electronic WIKA sensor, integrated into the high-quality mechanical differential pressure gauge, combines the advantages of electrical signal transmission with an on-site mechanical indication that remains readable during a power failure.
The QR code on the dial allows instrument-specific information such as the serial number, the order number, certificates and other product data to be retrieved from the internet easily and in the long term.
