Transmitter two-wire 4-20mA intelligent digital round table

I. Overview

Two-wire passive digital smart meter does not require a separate power supply, simply connect the instrument positive and negative series in the two-wire transmitter 4 ~ 20mA loop can display the transmitter changes in physical quantities, linear corresponding to decimal Digital display 4 ~ 20mA loop current change, the display range of changes in the range of -1999 ~ 9999. Transmitter loop current, both as a display instrument input signal, but also as a display instrument power supply. , Clear and intuitive, direct reading digital display, high precision, decimal point position adjustable, digital update speed can be set.

The digital display table is widely used for 2088, 133, 1151, 3051 series output 4 ~ 20mA need to display the pressure, temperature, humidity, flow, power transmitter and analytical instrument display, can be set to actual Physical quantity, can also show the percentage of physical changes. Simple, flexible. Cost-effective, welcome to use or OEM processing.

Second, the main technical parameters
