5485C HIGH-TEMPERATURE VELOCITY TRANSDUCER
Installation Manual
2-PIN CONNECTOR VERSION
(requires mating Model 4850-XXXX cable)
FIXED ARMORED CABLE VERSION
1180
DOC # M8109 • REV L (April 2018)
OVERVIEW
The Metrix 5485C High-Temperature Veloc-
ity Sensor is suitable for use in temperatures
up to 375
C. It is designed for gas turbines
O
and other machinery with high surface tem-
peratures where a velocity signal is desired.
The sensor's moving-coil design requires no
external power as it self-generates a signal
proportional to vibration velocity.
FEATURES
• Self generating, no power required
• Stainless Steel Housing
• Zero friction - infinite analog resolution
APPLICATIONS
• Large industrial gas turbines
• Furnace fan monitoring
HAZARDOUS AREAS
UL intrinsically safe for Class 1, Div. 1, Grps
(A-D); Non-incendive for Class 1, Div. 2,
Grps. (A-D). CSA intrinsically safe for: Class
1, Div. 1, Grps (A-D); ATEX/IECEx intrinsically
safe for: EEx ia IIC T1-T6 Ga.

- Page 2 INSTALLATION The sensitive axis of the transducer can be oriented in any direction. To ensure clean response to high frequency vibrations, the transducer must be securely mounted to a flat machined surface using four #6 (or 3mm) socket head screws. If a bracket is required, it should be of rigid construction to prevent spurious mechanical resonances in the pass band.
