Bently Nevada 81545-01 Case Expansion Monitor

The Bently Nevada 81545-01 is an advanced Case Expansion Monitor designed to measure casing growth in relation to the machine foundation. This system utilizes two DC Linear Variable Differential Transformers (LVDTs) for precise measurements of casing expansion. The monitor offers flexible alarm settings and display modes, making it suitable for various industrial applications.

Product Features

Dual LVDT Sensors: The 81545-01 uses two DC Linear Variable Differential Transformers (LVDTs) to monitor casing expansion relative to the machine foundation. This ensures highly accurate and reliable data collection.
Digitally Adjustable Alarm Setpoints: The monitor allows two independent, digitally adjustable alarm setpoints for flexible configuration. This feature ensures quick identification of abnormal casing growth.
Two Display Modes:
- Independent Channels Mode: Displays two separate channels of case expansion data.
- Differential Mode: Shows the difference between the two channels, with alarms activated only in this mode.
Epoxy Relays: The 81545-01 features dual epoxy relays for robust and reliable performance, even in harsh industrial environments.
