29.4 Sensors
Weigh module XN-322-2DMS-WM is compatible with strain gauge load cells
with the following load cell characteristic values: 0.25 mV/V; 0.5 mV/V; 1 mV/
V; 2 mV/V; 16 mV/V with a supply voltage of 5 V and a working resistance of
150
Ω
to 5000
Ω
.
29.5 Filter settings
The reading's accuracy and stability will depend on how the filter is config-
ured. If the filter has a high cutoff frequency, so that the goal is to have a
short refresh time for the reading, the resolution will be lower. If the filter has
a low cutoff frequency, resulting in a long refresh time, the measured value
will be more accurate and the transmission frequency (bus load) will be
lower.
The refresh frequency can be calculated by using the formula below. The cut-
off frequency must be configured in CAN object 5060
