When Should I Use a Signal Conditioner with a Proximity Probe System?
The CTC SC300 Series Signal Conditioner can be used with any PRO Line Proximity Probe Driver with voltage output to provide a 4-20 mA digital output signal proportional to peak-to-peak vibration. This can be an excellent, cost-effective solution for end users who prefer a simplified process signal as input for the local machinery protection or control system.
This provides a very similar output as CTC's PRO Line 4-20 mA Radial Drivers. As a result, CTC typically recommends for most new systems purchasing 4-20 mA current drivers instead of a proximity probe system plus signal conditioner, to save costs and eliminate unnecessary equipment.
The use of SC300 Series Signal Conditioners is ideal for cases where there are already voltage probes installed (or in stock) and the end user would like to get a 4-20 mA output, or where specialty configurations are desired.
Utilizing an SC300 Series Signal Conditioner will allow for additional configuration options to modify the 4-20 mA signal, including:
- Selecting a specific frequency range to monitor
- Additional scaling options
- Alternative methods of measuring the severity of vibration, like Pk-Pk, Peak, RMS, etc.
- Customized output smoothing features to avoid false alarms and trips
