Description

The 3300/46 3300/46-46-04-02-01 Ramp Differential Expansion Monitor measures differential expansion on large machinery using two proximity probes mounted on rotor ramp surfaces, providing one channel of measurement with increased range up to 50 mm. The 3300/46 Ramp Differential Expansion Monitor 3300/46-46-04-02-01 accepts two transducer signals with 10 kΩ input impedance and jumper-selectable scale factors of 100 mV/mil, 20 mV/mil, or 10 mV/mil. Signal conditioning accuracy is ±0.33% typical and ±1% maximum at 25°C.

The 3300/46 3300/46-46-04-02-01 Ramp Differential Expansion Monitor outputs voltage (0–+12 Vdc) and current (+4 to +20 mA) signals with 100 Ω output impedance and provides front coaxial and rear terminal buffered outputs. A non-multiplexing 83 mm vertical bargraph LCD displays magnitude and direction of differential expansion with ±1.6% resolution. Four alarm setpoints (two over, two under) and LED indicators for OK, Alert, Danger, and Bypass allow automated monitoring and alarm signaling. Operating temperature is 0°C to +65°C, storage -40°C to +85°C, and power consumption is 1.5 W. The 3300/46 3300/46-46-04-02-01 Ramp Differential Expansion Monitor is ideal for automated differential expansion monitoring in turbines, generators, and other large industrial rotating machinery.
