Technical data VT-HNC100-1-3X/S (1-axis version)
1)
If a 24 V transducer supply is implemented directly via the
VT-HNC100-1-3X/S (supply voltage is looped in), the transducer
specification has to be observed.
2)
If the factory settings are insufficient, the measurement technol-
ogy can be calibrated on site via software in a system-specific way.
3)
Configurable as current or voltage output.
