GE RV33‑1 Vibratory Speed Sensor Signal Conditioner Module

Technical Specifications Module Type: Vibration & Speed Pick‑Up Signal Conditioner Module Applicable System: Power‑Plant Turbine and Industrial Rotating‑Machinery Monitoring System Input Signal: Weak AC pulse signal from magnetic pick‑up sensor Output Signal: Conditioned standard square‑wave pulse signal Power Supply: 24VDC nominal auxiliary operating power Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: DIN‑rail mount compact module housing Certifications: CE, UL industrial monitoring‑component compliance

Functional Features Amplifies weak AC pulse signals output by magnetic speed‑and‑vibration pick‑up sensors. Performs noise filtering and waveform shaping for raw sensor pulse signals. Outputs standardized square‑wave pulse signals compatible with control‑system counter‑input channels. Front‑panel LED indicators display power‑supply status and valid pulse‑signal‑input activity. Built‑in circuit protection suppresses input‑side transient voltage spikes. Improves signal anti‑interference performance for long‑distance sensor‑cable transmission.

Application Scenarios Magnetic pick‑up sensor signal conditioning for power‑plant turbine shaft‑speed monitoring. Signal pre‑processing for industrial rotating‑machinery rotational‑speed measurement. Spare‑part replacement for legacy GE rotating‑equipment monitoring installations.

Structural Characteristics Compact enclosed module housing for TS‑35 DIN‑rail mounting. Front‑panel LED indicators for power‑on status and pulse‑input activity display. Rear‑side screw‑type terminals for sensor‑input, conditioned‑pulse‑output and 24VDC power‑supply wiring. Internal signal amplification, filter and waveform‑shaping circuit components. DIN‑rail locking clip realizes anti‑vibration mechanical fixation.

Working Principle Weak alternating‑current pulse signals generated by magnetic pick‑up sensor are transmitted to RV33‑1 input terminals. Internal amplifier circuit boosts weak signal amplitude; filter circuit eliminates high‑frequency electromagnetic noise. Waveform‑shaping circuit converts sine‑like raw pulses into stable square‑wave pulse signal.

Installation Requirements Install module on standard TS‑35 DIN‑rail inside monitoring cabinet. Connect 24VDC auxiliary power supply with correct polarity. Wire magnetic pick‑up sensor shielded cable to module input terminals. Connect conditioned pulse‑signal output terminals to corresponding control‑system counter‑input channel.
