The new VARAN PVAI 011 measuring bridge module from Sigmatek is used for precision measurements in hard real-time. With a 12-bit resolution, measurement values from scales, force, pressure, acceleration, torque and temperature sensors are transmitted within a few µs.
The IP65 protected measurement value converter can be placed directly in the field level near the sensor, eliminating the effects of electrical noise on measurements. Due to the short length of VARAN frames, data can be resent within the same bus cycle in the event of an error. The extremely robust VARAN bus system makes it possible to implement highly dynamic regulation with deterministic properties. The user is thus provided with a safe and complete system for fast precision measurements.
The power for the electronics and sensors is supplied over the VARAN Bus User Organisation-certified 8-pin M12 connector (2 reserve pins) with the corresponding hybrid cable, which was designed for harsh industrial conditions. Since only one connector is required for power and bus signal transmission, connection errors are practically eliminated. In addition, costs and assembly time can be reduced. The measurement recorder is also connected over an M12 connection system (4-pin).
