Tension sensors Series ST461 have been designed to monitor tension on high-voltage lines. They are installed in the double terminal tower clamp configuration, between the end tower and insulators.
They are realized to be used in difficult outdoor applications. There is no need to change the all system, they are a little heavier than the element they substitute.
Sensors are equipped with digital electronics (Modbus RS485) and they can be installed where electromagnetic fields and high electrical noise are present.
Two versions of the sensor ST461 are available:
|Safe load limit|
120% FS (measurements are not guaranteed over FS value)
|Temperature effect on measurement|
20 bit nominal
|Tolerance on power supply|
Power supply 12 Vdc: 40/50 mA
|Accepted communication speed|
from 4.800 to 115.200 baud
|Compensated temperature range|
from -20°C to +70°C
Sensors are compliant with following standard:
