ALM400 Load Indicator - Anchor line tension

		DynaTension model ALM400 Mooring Tension Monitoring System The DynaTension model ALM400 infers anchor line tension from the vibration frequency of a span of the cable without physically contacting the cable. A non-contact exciter sensor assembly (ESA) that only weighs 40 lbs silently plucks the cable with a magnetic pulse force to initiate and maintain cable vibration. A sense coil in the ESA senses the vibration, a Signal Processor Unit processes the frequency sensed and outputs tension in either analog or digital format. Either a high tension alarm or a low tension alarm is provided. Additionally, the amount of line paid out or in may be measured and displayed along with line tension.
KEY FEATURES: No physical contact – nothing to wear out Infers tension from frequency – never requires calibration No hysteresis or friction error - very high accuracy and repeatability ESA can be installed with cable under load – no drilling downtime to install Failure of any component very rare – low maintenance costs Heaviest component only 40 lbs – easy to replace
