Vibrating Wire Strain Gauges for Bridge, Tunnel & Dam Monitoring: Complete Selection Guide

Vibration Signal Conditioning Module for Industrial Monitoring
Vibration Signal Conditioning Module
A vibration signal conditioning module takes the low-level output from accelerometers, velocity pickups, or proximity probes and turns it into something a monitor or controller can actually use. Without this step, raw sensor signals are often too weak, too noisy, or in the wrong format. Kingmach builds these modules for engineers who need a straightforward, no-fuss way to connect field sensors to PLCs, data loggers, or rack-based monitoring systems. The design focuses on adjustable gain, switchable low-pass filtering, and standard output ranges like 4–20 mA or ±10 V. You won't find exotic features that never get used, just a solid signal path that preserves measurement accuracy from the sensor to the DCS. They come in compact DIN-rail housings and draw minimal power, so they fit tight panel spaces easily. For project-specific requirements—like custom bandwidth or special sensor compatibility—Kingmach’s engineering team can tweak the standard design without long lead times.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Most vibration signal conditioning modules from Kingmach accept common sensor types, including IEPE accelerometers (with constant-current diode), moving-coil velocity sensors, and eddy-current probes with driver. The input stage typically has a selectable gain from 1 to 1000, letting you scale a 100 mV/g accelerometer to a full 10 V output at the vibration levels your machine actually sees. Low-pass filtering is handled by a two-pole Butterworth or Bessel filter with corner frequencies selectable by DIP switches—common choices are 100 Hz, 500 Hz, 1 kHz, and 10 kHz. The output side gives you simultaneous buffered AC for spectral analysis and DC proportional to RMS or peak value, available as 4–20 mA and ±10 V. Power is 24 V DC nominal, with typical consumption around 1.5 W. Modules mount on standard 35 mm DIN rail and the removable screw terminals make wiring easy. Kingmach offers customization for things like multi-channel units, integration time constants for the RMS converter, or conformal coating for humid environments. Support engineers can help you dial in the right settings during commissioning, and global distributors keep spares accessible.

Common technical questions
What types of vibration sensors can be connected to this module?
The module works with standard IEPE accelerometers, velocity transducers, and eddy-current probes (via driver). We configure the input stage to match your sensor’s sensitivity and impedance during order, but some models have jumpers for field adjustment.
Can I adjust the gain and low-pass filter cutoff after installation?
Yes, most models include DIP switches or potentiometers on the front. Gain ranges like 1–1000 and corner frequencies from 10 Hz to 10 kHz are common. Specific options depend on the ordered variant.
What are the power supply requirements?
Typically 24 V DC, with wide-range inputs from 12 to 30 V DC accepted. Power draw stays below 2 W, so no special supply sizing is needed.
Is the module suitable for harsh environments?
The enclosure is industrial-grade (IP40 typical) and boards have conformal coating. It handles -20°C to +70°C, but direct moisture or heavy dust should be avoided unless a higher IP housing is specified.
How do I integrate it with a PLC or data acquisition system?
The conditioned output is standard 4–20 mA or ±10 V, which connects directly to analog input cards. An RS-485 Modbus RTU option is available for digital systems—just mention it when ordering.
