DUAL-CHANNEL CASE EXPANSION MONITORING

ENTEK C6687 6687
Dual-Channel Case Expansion Monitor

Continuous absolute or shell-expansion measurement for compatible ENTEK IRD 6600 Series machinery-protection systems.

MONITOR ROLE

Absolute / Shell Expansion

Two measurement channels support casing-growth observation during changing machine conditions.

Product snapshot

The C6687 accepts one or two LVDT or non-contact probe inputs and presents both channels through dual bar graphs with a shared numeric display. It is intended for monitored casing or shell movement, not general-purpose PLC I/O.

System fit

Use in a compatible ENTEK IRD 6600 rack with the documented backplane, power supply, transducer arrangement and alarm configuration retained for the installed machine.

CONDITION

New Original

WARRANTY

One year

PERFORMANCE, EFFICIENCY & APPLICATIONS

TECHNICAL OVERVIEW

MEASUREMENT BEHAVIOR

Two channels for continuous machine-case movement supervision

The monitor converts conditioned transducer signals into channel displays and alarm decisions within the 6600 rack architecture.

Performance & Efficiency

Dual bar graphs make both channels visible at once, while the numeric display alternates between channel values for closer reading. Configurable sensitivity supports the installed transducer scale, and first-out alarm information helps operators identify the initiating event during a machine condition change.

Application Scenarios

Use the C6687 to observe turbine casing expansion, shell growth and related thermal movement during startup, load changes and shutdown. Typical installations include monitored turbines, compressors and other critical rotating assets using an established ENTEK IRD 6600 protection rack.

BRAND CHARACTERISTICS & APPLICATION FIELDS

MACHINERY MONITORING

Brand characteristics

Application fields

ENTEK IRD 6600 monitors use modular rack architecture and configurable measurement channels for established machinery-protection programs. Centralized supervision keeps channel status and alarm behavior visible at rack level.

The C6687 suits industrial assets where controlled casing movement must be observed together with other protection variables. It helps maintenance teams compare thermal movement with the machine operating condition.

Channel visibility

Dual bar-graph and numeric indication provide clear two-channel status for inspection and operating checks.

Power generation

Tracks turbine shell movement through startup, load changes and controlled thermal transitions.

Configurable scale

Sensitivity settings can match the documented LVDT or probe calibration retained in the protection rack.

Oil & gas

Supports critical compressor and rotating-train monitoring where casing growth can affect machine alignment.

Rack integration

Backplane integration supports centralized alarms, first-out indication and coordinated protection hardware.

Plant maintenance

Supports like-for-like rack service, lifecycle replacement planning and configuration verification.
