What it represents
Monitors the density of a medium used by electrical equipment.
In a drafting package, connect this reference to the density sensor and monitored compartment. The associated drawing should trace the density alarm, lockout or operating permission; the number identifies the role and does not specify the terminal arrangement, ratings or operating settings.
How to read it
- Identify the density sensor and monitored compartment.
- Trace the density alarm, lockout or operating permission.
Information to show or reference
- Label the density sensor and monitored compartment.
- Cross-reference the density alarm, lockout or operating permission.
- Identify the device tag, manual revision and logic drawing that define this implementation.
A distinction that matters
Density is distinct from pressure; temperature-compensated gas-density supervision should not be relabelled as 63 solely because a gauge is present.
