Rated load
for sensor it is a size of force, which specifies
top value of measuring range (given value for sensor as
bridge range
-
TRA
in N).
Applied load
is the biggest force, which have
unambiguous connection between force and output
signal (signal value is changing linear in relation to force). It can count max. M
150%
of sensor range
(bridge).
Cut-off load
is the biggest force, which can Take each sensor without it damage. It can count max.
200%
of sensor range.
Destroying load
means force applied to sensor Shaft, which exceeding can cause to mechanical
damage of the sensor.
Constant of e.g. KMM60 sensor is 1,5mV/V
2%. Error of the sensor is specified by following values:
tolerance of linearity 0,2% of measuring range, zero tolerance 2% of measuring range, hysteresis
0,2% of range and creep measured in time of 30 minutes 0,1%. Temperature factor of zero point
and constant is 0,1% of range/10
o
C. Bridge resistance on input has 380om ±10% and output
resistance has 350om ±5%.
