High-precision digital pressure gauge with RS485 and 4-20mA output.
The digital pressure gauge LEO3 outputs the pressure value as an analog signal for display. With an RS485 interface, it can be integrated into a BUS system and communicate with a computer. Current measurements of 4-20 mA are displayed simultaneously with the pressure value. Minimum and maximum values can be displayed with just a button operation. Power is supplied directly through the 4-20 mA circuit. 【Main Features】 - Various pressure units can be selected (e.g., bar, hPa, kPa, MPa, etc.) - Zero point calibration via button - Minimum/maximum value display - Analog 4-20 mA output - High accuracy: ±0.1% FS @ 20-25℃ - Power supply voltage: 8-32 VDC - RS485 digital signals are also output, allowing connection to a PC (license-free/free software is also available).
