The ABUS LPI-PT Loop Powered Indicator for Pressure Transmitter is a microprocessor controlled loop powered display for any 4 ~ 20 mA standard signal. It does not require its own separate voltage source as it is supplied directly from the measuring current loop.
The measured value is displayed on a 4-digit LCD with a wide max. display range of -1999 to +9999 digits. The operating range of the display device can be directly adjusted to the transmitter without any accessories being required. Simply enter the maximum and minimum measuring range limits and the decimal point position.
