Analog Load Cell To PC Converter

Brand: Test Instruments

Model No: TES-ATC-108A

 

Input of analog load cells:

1~3mV/V,300~2000 Ohms.Device power up

to 12 psc 350 Ohms load cells.

Output:standard RS232,

Can connect to PC direct.

Light insulation type

Non-linearity compensation

And Filter treatment Exterior led show working order

 

Dimensions

(In mm. 1mm = 0.03937 inches)

 

Work Principle

This is a based weighting solution,It can be used for either analog strtic weighing.No need the indicator,and it has a low cost.Usually,it connects the juncton box between the computer.

The signal of some analog load cells will be magnified after analog adding by the junction box, which will be dealed with by MCU after A/D conversion,then will output to PC by RS232 module.

The data for deviation of synthesis error,TKo,TKc are typicl values.The sum of these data meets the requirements

according to OIML R60.The data will rest with the analog load cells.

 

Communication

 

The TES-ATC-108A is equipped with standard RS-232 output interface,it can communicate with commputer or

connect to indicator.

Serial communication baud rate:9600bps,1 bit start bit,8 bit data bit,1 bit stop bit, no parity bit(use

byte verify and mode verify).
