UA-3122

Key benefits

• Flexible, mixed-sensor connectivity: Each of the 3 channels provides dedicated connectors for bridge, charge, and direct/CCLD signals—ideal for labs that use multiple sensor types.
• Faster setup for strain/bridge testing: 15‑pin D‑sub connections let you configure completion resistors on the cable plug, simplifying quarter-/half-/full-bridge strain gauge setups.
• Easier verification and troubleshooting: Buffered monitor outputs run in parallel, so technicians can quickly check signals without disrupting the measurement chain.
• Supports the use of sensors with high EMI immunity which are well-suited to difficult environments
• Works where grounding is challenging: Suitable for applications where good ground connections are difficult to achieve.
• At-a-glance system status: LED indicators for input, output, overload, and cable break reduce downtime and speed diagnostics.

Applications

• Bridge sensor measurements
• General sound and vibrations measurements
• Measurements in difficult environments or where good ground connections are difficult to achieve

DAQ module compatibility

• LAN-XI 3057 Bridge Input Module

Connectors

3 channels, each with:

• 1 × 15-pin D-sub (F) for bridge input
• 1 × 10-32 UNF (F) for charge input
• 2 × SMB (jack) for direct/CCLD input and monitor output

Supported signals

Bridge sensor measurements:

• 1/1, 1/2 and 1/4 bridge strain gauges
• Strain gauge based sensors (force, mass and torque)
• Piezoresistive accelerometers and pressure transducers
• Variable-capacitance accelerometers

Sound and vibration measurements using:

• CCLD sensors
• Direct voltage signals
• Charge accelerometers

Notes

• Only one input type (bridge, charge or CCLD/direct) is used per channel at a time.
• CCLD = constant current line drive, also known as DeltaTron^® (ICP^® and IEPE compatible)
