81544-01 (78462-02) is an XDUCR I/O & Record Terminal developed by Bently Nevada. It is a part of the Bently Nevada 3300 series. This is a Terminal module associated with the Bently Nevada 3300/45 Dual Differential Expansion Monitor.

Functional Description

• Two channels of continuous differential expansion monitoring are offered by the 3300/45 Dual Differential Expansion Monitor. The differential expansion's size and direction are both observed. For each channel, there are two over and two under alarm setpoints that can be configured. Machines that only need the measurement at one spot can turn OFF Channel B of the monitor.
• The measurement of the axial position of the rotor with regard to the machine casing at a certain distance from the thrust bearing is known as differential expansion. Axial clearances are affected by changes in an axial position in relation to the casing, which is often brought on by thermal expansion during startup and shutdown.
• Typically, a proximity probe transducer affixed to the machine's casing is used to measure a rotor's axial surface (such as its collar). Typically, the measurement is included in a Turbine Supervisory Instrumentation system.

81544-01 (78462-02) Features:

• Magnitude and Direction of Differential Expansion Monitoring
• 4 Alarm Setpoints: 2 Over and 2 Under Alarms
• 2 Proximity Probe Transducer Signals
• Input Impedance: 10 kΩ
