Digital Pressure Indicator DPI
DPI types of Digital Pressure Indicators are designed to display system pressure using 4-digit ultra-bright LED display where multiple pressure sensor can be connected. The unit standardly uses -1..24 bar, 0..25 bar and 0..60 bar pressure sensors. The sensor input is widely configurable and it can be used for 0.5-4.5 V and 0-10 V transducers or 4-20 mA transmitters.
Optionally, an I/O driver can be integrated for activating warning output, regulating the system pressure, etc. The Digital Pressure Indicator can be used as a stand-alone system or as a part of MMX system connected via CAN bus to IO Controller. Several slave-remote pressure indicators (RPI) can be connected to a master indicator DPI to show the same value on different locations.
