The GE Druck DPI 104 is a microprocessor-controlled digital pressure gauge that delivers precision and robust functionality in a compact, easy-to-use package. Designed as a high-accuracy replacement for traditional analog test gauges, this instrument combines advanced silicon sensor technology with user-friendly features, making it an economical and reliable solution for a wide range of pressure sensing, process monitoring, and calibration applications .
The specific model MSIP-REI-KTM-DPI104 with part number 5311783 is a 700 bar variant, suitable for demanding hydraulic and pneumatic systems.
Key Features & Benefits
-
High Accuracy: Provides 0.05% Full Scale (FS) accuracy, which includes the combined effects of non-linearity, hysteresis, repeatability, and temperature influences from -10°C to +50°C (14°F to 122°F) .
-
Versatile Pressure Measurement: Supports a wide working pressure range up to 20,000 psi (1400 bar) across different configurations; this specific unit is intended for the 700 bar (10,000 psi) range .
-
Large, Easy-to-Read Display:Â Features a large 5-digit LCD with a clear pressure reading. The display also includes a circular 20-segment bar graph and percentage indication for quick visual estimation of pressure from 0 to 100% FSÂ .
-
Advanced Functionality:
-
Min/Max, Tare, and Alarm Functions: Captures peak values, zeroes out offsets, and provides configurable alarms to alert operators .
-
Pressure Switch Test: Allows for testing and calibration of pressure switches by capturing set and reset points .
-
Analog Output & RS232 Interface:Â Offers a programmable 0-5V analog output and an RS232 serial interface for remote monitoring, data logging, and connection to a PCÂ .
-
-
Durable Design & Build: Housed in a rugged ABS/PC case with a 95mm diameter, the DPI 104 is designed for industrial environments. The pressure cavity is manufactured from stainless steel and Inconel for compatibility with aggressive media .
-
Flexible Installation: The instrument housing can be rotated 320° around the pressure fitting, and the faceplate can be rotated to any orientation for optimal viewing in any mounting position .
-
Network Capable: Up to 99 DPI 104 instruments can be connected together in a daisy-chain network for centralized monitoring .
