Suparule 300E - Cable Height Meter S300E, CHM300E

The Suparule 300E is a handheld Cable Height Meter instrument for measuring cable height distance, sag and overhead clearance. It is the present day alternative to measuring poles. The Suparule 300E uses ultrasonic signals to identify the height of overhead cables of up to 75 feet / 23 metres. Ideal for operators in the utilities industry such as telecommunications and electricity, the CHM300E (Cable Height Meter) measures the height of up to 3 wires. If the height of only a single wire is needed we recommend this model, however if 6 wire height measurements are required then we suggest the CHM600 or CHM600E models. Since 1989, Suparule has used its considerable technical skills and resources to develop a number of unique technologies. These technologies have been patented and are now trademarked as SMF Technology™ (Suparule Magnetic Field Technology). The technologies are based on the measurement of the magnetic and electric fields generated from a current carrying conductor. The unique advantage of SMF Technology™ is that measurement is done non-invasively and the sensor rejects interference from other external fields. The solutions are achieved at a significantly lower cost, with higher accuracy levels than conventional measurement solutions.  Features of the CHM300E Cable Range: 23m / 75ft 3 Wire Measuring Operating temperature: -10 °C to 40 °C  How the Suparule Works The CHM300E emits from the cone transmitter a short burst of sound. The instruments processor then calculates the time taken for the sound to be reflected from the cable back to the Suparule Cable Height Meter. The result is then shown in either imperial (feet and inches) or metric (meters) format on the user display. A sensor is mounted on the front of the instrument to measure the actual air temperature and compensate for the speed of sound which varies in different temperatures. To operate the Cable Height Meter simply stand beneath the cable and align longitudinally (looking down the cable line) and press the ‘ON’ button. This will power the instrument and allow the temperature to stabilise. The press ‘MEASURE’ and if required gently tilt the Suparule CHM until the result is shown on the display.
