WEIDMULLER has introduced the Waveanalog Pro Bridge, a signal conditioner for measuring bridge signals used to power and convert input bridge transducers.
Bridges or strain-gages are commonly used to measure weights or forces. The use of the Waveanalog Pro Bridge can eliminate the need for expensive PLC or DCS modules. It does this by providing the bridge excitation voltage and also converting the mV bridge output to a standard voltage or current signal which can be easily used by the control system.
As one of the newest additions to the Waveseries signal conditioner line, the Pro Bridge utilises screw or tension clamp connection technology. Pluggable connectors allow easy, quick installation and maintenance while its slim design (17.5mm) allows higher density in panel construction.
With DIP-switch selectable bridge excitation voltages, this signal conditioner allows unipolar or bipolar voltage inputs from 0...10mV to -500...500mV, and provides a choice of outputs of 0...5V, 0...10V, 0...20mA, or 4...20mA. The power supply of 18-30 Vdc for this signal conditioner is cross-connectable to adjacent modules to eliminate redundant wiring.
The Waveanalog Pro Bridge is ideal for machinery utilising load cells, which are commonly used in chemical processing and mixing operations, food industries, and metal process equipment. Other applications include robotics and machinery where large loads are weighed before processing on CNCs or other equipment.
