Dear Masters
I have bought a load cell(made in china) without any datasheet and this is the
only data that i could get from seller in a very small piece of paper!
1-capacity(kg): 60
2-Thread Type : M
3-Calibration Mode :Compression
4-Sensitivity: 2+-0.2mv/v
5-Input Impedance : 415+-15 ohms
6-Output Impedance : 350+-3 ohms
7-Insulation Resistance >2 G Ohms
8-Test excitation : 10v DC
9-Zero Balance <+-3% of cn/k
10-Total Error : 0.020% of cn/k
11-Non Repeatibility : 0.010% of cn/k
12-Zero Return : 0.023% of cn/k
13-Temperature effect on zero : 0.0035% /C
14-Temperature effect on Sensitivity : 0.0014% /C
15-Compensated Temperature : -10~+40 C
16-Safe Temperature : -25~70 C
-------------------------------------------
Cable Color Code
Red=+Excitation
Green=+signal
White=-Excitition
Blue=-signal
-------------------------------------------
I want to connect this device to avr microcontroller and measure weight
but i can't find any good article about load cells and meaning of above specifications.
can anybody help me?
