Introduction
Weighing indicator XK3190-C8+ adopts fast speed ∑-Δ A/D conversion technology. It is widely applied in electronic batching scale、electronic fix-value scale and electronic catchweigher, sort of control system. Meanwhile, it has function for Max and Min limitation alarm and peak value preserving.
Standard Function
3 inputs, 3 outputs (3 output relays inside) control
High precision A/D conversion with readability 1/30000
With 5 points nonlinearity amend
If change the former indicator, no need to re-calibrate, only to input parameter of former indicator
Embodies with automatic grarimetric filling instruments, catchweigher, alarm for max and min limitation and peak value preserving functions
Able to set fixed-value, pre-act value, Max-min limitation, and delay time freely based on different applications
1-2 materials available for plus/minus scale; external, self-testing, and free max and min modes are available for catchweigher
Standard RS-232/422/485 communication interface, baud rate and way of communication is optional
Standard scoreboard interface serial sending signal by 20mA current loop (constant current)
Precise simulate signal output with mode of 4-20mA/0-20mA/0-5V/0-10V optional, adjustable
Accumulative weight and times is able to be stored, check, delete, and with date-protection when power cut off
Able to connect with serial printer to print weighing record, accumulative amount or combined information, kg, t, g, lb is an optional print unit
Zero tracking, range for zero (automatic and manual) is free to be set
Strong anti-jamming and reliability
ESD protection performance: touch 6KV, air 8KV.
Able to recover from factory setting
