Monitoring the tension in cables is significant in some ice drill and deepwater applications. Take our RECoverable Autonomous Sonde (RECAS) for example. It is able to melt a hole to the bottom of ice sheet and is able to move upwards. A winch is installed inside RECAS to release and recover the cable, whose tension needs to be monitored in real time in order to control the behavior of the winch. The high pressure of deep water and limited installation space pose great challenges in sensor development. In this paper, two editions of newly designed deepwater tension sensors are proposed. The first edition is based on a fresh hydraulic load module that operates in high pressure environment and the second edition tension, which aims to improve the accuracy, applies a newly designed watertight load module. Detailed force transmission and characteristic analysis of the sensors are carried out. The sensors have got through a series of experiments, including calibration experiments, pressure experiments and field experiments. The resultant accuracy of the second edition sensor, which has a better performance, is over 2% under the measuring range of 1000 kg and the dimension of the final sensor is as compact as 150 mm × 137 mm × 86 mm.

冰钻应用深水张力传感器的设计与分析

在一些冰钻和深水应用中，监测电缆的张力非常重要。以我们的可恢复自主探测仪 (RECAS) 为例。它能够在冰盖底部融化一个洞，并能够向上移动。RECAS 内部安装了绞盘，用于释放和回收电缆，需要实时监控其张力以控制绞盘的行为。深水的高压和有限的安装空间对传感器的开发提出了巨大的挑战。在本文中，提出了两种新设计的深水张力传感器。第一版基于在高压环境下运行的全新液压负载模块，第二版张力旨在提高精度，应用了新设计的防水负载模块。对传感器进行了详细的力传递和特性分析。传感器已经通过了一系列实验，包括校准实验、压力实验和现场实验。性能更好的第二版传感器在1000公斤的测量范围内精度超过2%，最终传感器的尺寸紧凑到150毫米× 137毫米× 86毫米.
