Description
EPRO CON021 916-160
Technical Specifications Power supply -23 VDC to -32 VDC; analog output -4 V to -20 V; frequency response DC to 20 kHz; rise time <15 μs; static measurement range ±2 mm; center gap 2.7 mm; linearity ≤ ±1.5%; operating temperature -30 ℃ to +100 ℃; weight approximately 120 g; Lemo probe input connector, screw terminals for power and output signal.
Functional Features Real-time temperature compensation of probe gain; continuous cable fault detection for short and open circuits; low-noise analog output for vibration spectrum analysis; compatible with VM600 and other EPRO machinery monitoring racks; ATEX and CSA certification for hazardous area installation.
Application Scenarios Turbine generator set shaft vibration monitoring, compressor rotor axial thrust monitoring, pump shaft orbit measurement, rotating equipment keyphasor speed pickup.
Material Composition LMgSi 0.5 F22 magnesium alloy housing; multilayer FR4 signal PCB; high-stability amplifier components; sealed Lemo quick-lock connector; screw terminal block rated for 1.5 mm² wire.
Structural Characteristics Compact panel mount housing; front Lemo socket for probe cable; side terminal block for negative supply and analog signal; four M5 mounting screw points; internal circuit conformal coating.
Working Principle The unit generates high-frequency excitation for the eddy current probe. Changes in probe-to-metal gap modify coil impedance, and the conditioning circuit transforms impedance variation into linear analog voltage. The output voltage is transmitted to monitoring rack ADC channels for vibration and position calculation.
Installation Requirements Mount inside non-hazardous control cabinet; use matched EPRO probe and extension cable assembly; route probe cable separate from power cables; apply anti-static procedure before handling circuit assemblies.
Operation Notes Confirm supply polarity before energizing; set mechanical probe gap to nominal center value during commissioning; inspect Lemo connector locking ring after machinery maintenance access.
