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%.
