The DPI 104 combines advanced silicon sensor technology with a compact, user-friendly package. It serves as a reliable and economical solution for a wide range of pressure sensing applications, functioning as a stand-alone process indicator or as a precision reference when used with Druck hand pumps . Its robust design and feature set make it a versatile tool for test, calibration, and process monitoring.
Key Features & Benefits
-
High Accuracy: Delivers an accuracy of ±0.05% Full Scale (FS), which includes the effects of non-linearity, hysteresis, repeatability, and temperature from 14°F to 122°F (-10°C to 50°C) .
-
Wide Pressure Ranges: Available in various ranges from 0-10 psi up to 20,000 psi (1400 bar), with different pressure types (Gauge, Absolute, Sealed Gauge) .
-
Intuitive Display & Interface: Features a large, easy-to-read 5-digit LCD with a 20-segment circular bar graph for a quick visual indication of pressure from 0 to 100% . The display updates twice per second .
-
Flexible Units: Allows selection from eleven different pressure units (e.g., psi, bar, mbar, kPa, MPa, kg/cm², inHg) .
-
Advanced Functions:
-
Switch Test: Captures and displays the open and closed values from an external pressure switch .
-
Min/Max & Tare: Can record minimum and maximum pressure values and zero the display for relative measurements .
-
Alarm Output: Features a high/low alarm with an open-drain output .
-
Analog Output: Provides a programmable 0 to 5 V analog output signal for control and data logging .
-
-
Data & Connectivity: Equipped with an RS232 serial interface for data transfer to a PC and the ability to network up to 99 units in a daisy-chain configuration . Optional SicalPro software allows for remote control and logging .
-
Durable & Adaptable Design:
-
Robust Enclosure: Sealed to IP65 (dust-tight and protected against water jets) in an ABS/PC plastic case .
-
Wetted Materials: Available with an all stainless steel (316) or Inconel pressure cavity to ensure compatibility with aggressive media .
-
Adjustable Mounting: The housing rotates 320° around the pressure fitting, and the display can be rotated for optimal viewing in any orientation .
-
-
Intrinsically Safe Option: An intrinsically safe (IS) version of the DPI 104 is available with certifications (ATEX, IECEx) for use in hazardous areas .
