Description The SupaRule Cable Height Meter is a handheld meter for measurement of cable sag, cable height distance, and overhead clearance of conductors. It is a modern alternative to telescopic measuring poles. The SupaRule Cable Height Meter utilises ultrasonic signals to determine the height of overhead cables up to 15 meters (23 meters with the 600 model).
Used by line operators within the utilities industries, e.g., electricity and telecomunications, the CHM 190 measures the height of a single wire.
How It Works The Cable Height Meter emits short bursts of sound which originate from the cone-shaped transmitter. The microprocessor in the instrument calculates the elapsed time for the burst of sound to be reflected from the cable back to the instrument. The result can be displayed in either imperial or metric format.
To account for the fact that speed of sound varies with temperature, a temperature sensor, mounted at the front of the instrument, senses the actual air temperature, and automaticcaly compensates.
Applications Applications include height measurement of:
SAG (lowest point to ground)
Clearances on construction sites
