Abstract
A tension monitoring apparatus is used for installing an underground utility by retraction that is applied to the utility. The tension monitoring apparatus includes a sensor for inground sensing of the tension force that is applied to the utility to produce a sensor signal. A processor monitors the tension force in a series of measurement intervals such that a plurality of tension force readings is generated for each of the measurement intervals. The processor stores a data set including a maximum tension force selected from the plurality of tension force readings for each one of the measurement intervals and copies the data set to a different location to create a copied data set after installation of the utility for subsequent selection and presentation of an overall maximum tension force.
