Pressductor Sensor Technology and Excitation
The unit provides AC or DC excitation for Pressductor type sensors. AC excitation eliminates thermoelectric voltage errors from the measurement. The ABB 3BSE003911R0001 generates a precise 2.5 kHz sine wave for sensor drive. This frequency avoids interference from 50/60 Hz power lines. The unit senses the sensor’s magnetic permeability change under load. A green LED indicates proper excitation and sensor connection status. The unit automatically compensates for cable resistance and temperature effects.
Signal Processing and Force Measurement
Each channel amplifies the low-level sensor signal for accurate conversion. The unit filters out mechanical vibration noise from rolling mills and presses. The ABB 3BSE003911R0001 provides programmable low-pass filters from 1 Hz to 100 Hz. The 16-bit ADC converts each channel with high resolution and linearity. The unit outputs raw force values to the control system via the backplane. A yellow LED flashes when any channel detects a sensor wiring fault. The unit supports both differential and single-ended sensor connections.
Installation and Operational Guidelines
You must insert this unit into any standard Procontrol I/O rack slot. The backplane supplies 5V and 24V DC power to the unit automatically. The ABB 3BSE003911R0001 draws approximately 250 mA from the 5V supply rail. You must use shielded twisted-pair cables for all Pressductor sensor connections. This practice prevents electrical noise from corrupting millivolt-level signals. The unit requires no external battery for normal force measurement operation. You should perform a zero calibration after installing new sensors. The operating temperature ranges from 0°C to 55°C.
