The GE Druck DPI 104 is a microprocessor-controlled digital pressure gauge that combines precision and functionality in a compact, robust, and simple-to-use package. Designed for the 1000 PSI gauge pressure range, this model delivers reliable performance for a wide array of pressure sensing, process monitoring, and calibration applications. Whether used as a standalone process indicator or as part of a test kit with a Druck hand pump, the DPI 104 provides an economical yet highly accurate solution .
Key Features & Benefits
-
High Accuracy: Offers 0.05% full scale (FS) accuracy, including non-linearity, hysteresis, repeatability, and temperature effects from 14°F to 122°F (-10°C to 50°C) .
-
Versatile Display: Features a large, easy-to-read 5-digit display with a circular 20-segment bar graph for quick visual reference of pressure from 0 to 100% full scale .
-
Flexible Pressure Units: Provides eleven selectable pressure units (kPa, MPa, kg/cm², psi, mbar, bar, inHg, inH₂O, mH₂O, mmH₂O, and mmHg) for global compatibility .
-
Integrated Functions: Includes essential capabilities such as Minimum/Maximum recording, tare, alarm functions, and a pressure switch test for capturing open and closed values .
-
Analog Output: Programmable 0 to 5 V analog output for integration with data acquisition systems .
-
Robust & Durable: The housing is splash-proof to IP65, and the pressure cavity is constructed from stainless steel or Inconel for compatibility with aggressive media .
-
Adjustable Mounting: The gauge housing rotates 320° around the pressure fitting, and the faceplate can be rotated to any orientation for optimal visibility .
-
Connectivity & Networking: Features an RS232 serial interface. Up to 99 DPI 104 units can be networked together in a daisy-chain configuration .
-
Extended Capability: Can be connected to Universal Pressure Modules (UPM) to enhance accuracy and extend the pressure range .
