  • Page 4: Introduction

    Introduction The Druck DPI 104 is a digital pressure indicator that measures the pressure of liquid, gas or vapor and shows the pressure value on a liquid crystal display (LCD). It also has the Intelligent Digital Output Sensor (IDOS) technology to use data from a Universal Pressure Module (UPM).

  • Page 9: Installation

    Installation This section shows how to install and connect the DPI 104. Warning: To prevent an explosion or fire, use only the GE specified battery and external supply. DPI 104 Battery Use the procedures in Table 4 to install or replace the battery.

  • Page 10: Pressure Connections

    Pressure connections CAUTION: Do not use the body of the DPI 104 to tighten the pressure connection, this can cause damage. Use the flat faces on the pressure connector to hold the body and tighten the pressure union. Use an applicable method to seal the pressure connections, and then tighten to the applicable torque (Figure 1 and Table 5).

  • Page 11: External Power

    Table 3, page 4 gives the optional accessories that use the connector. Note: Use only original parts supplied by the manufacturer. The RS232 interface makes a serial network of units (maximum: 99). Refer to menu operation, page 5.

    The switch symbol and the value on the main display flash to give the switch condition and the switch pressure. Press To reset the monitor function. Menu: Calibration Refer to the menu operations section. Menu: Set low/high Use the alarm function to show when the pressure is not in the alarm specified limits for the system.

  • Page 15: Menu: Supply Voltage Output (Vout)

    Menu: Supply Use the Vout function to supply a voltage output (0.05 to 5 V) to an voltage output (Vout) external system. Two options are as follows: P-V: Vout is proportional to the pressure value on the display. US: User mode. Set a value in the Vout register (0 to 100%) to control an external pressure regulator.

  • Page 16: Menu: Set Vout Scale Factor

    Menu: Set Vout scale When the Vout function is set to P-V or US mode, the Vout scale factor factor becomes part of the Vout calculation (refer to menu operations). If the pressure ranges for the DPI 104 and the external pressure regulator are different, an applicable scale factor (0.01 to 9.99) must be set.
