Under Water Load Sensor

Underwater force sensor designed to measure loads acting on suspended or rigid plates subjected to wave action or other forces in experimental wave flumes.
The Under Water Load Sensor is designed for estimating the force acting on suspended or rigid plates mounted against waves or other forces. It uses an electro-inductive sensing arrangement with a diaphragm to detect the force acting on the measurement surface. The sensor provides force measurements with selectable ranges, fast response, and a 0 to 5 V output, making it suitable for experimental studies of wave-induced forces and underwater structures.

Overview

The Under Water Load Sensor is designed to measure the force acting on
suspended or rigid plates that are subjected to wave action or other forces.
It is suitable for experimental measurements where underwater force
characteristics need to be recorded and analyzed.

The sensor uses an electro-inductive sensing principle and a diaphragm to
sense the force acting on the measurement surface. The system is designed
to provide a fast response for recording changes in underwater force.

Key Features

  • Designed for underwater force measurement
  • Suitable for suspended and rigid plates
  • Electro-inductive sensing technology
  • Non-contact signal pickup
  • Fast response time
  • Selectable measurement ranges
  • 0 to 5 V output
  • Low-impedance output circuit
  • Suitable for long cable operation
  • 15-metre standard cable

Measurement Principle

The sensor uses an electro-inductive type sensing arrangement with a
diaphragm to sense the force acting on it. The movement of the diaphragm
due to applied force is detected by the sensor and converted into an
electrical output.

The sensing arrangement provides a non-contact electro-inductive signal
pickup, allowing the force acting on the measurement surface to be
recorded for experimental analysis.

Applications

  • Underwater force measurement
  • Wave flume experiments
  • Hydrodynamic model studies
  • Measurement of force on suspended plates
  • Measurement of force on rigid plates
  • Wave-induced force studies
  • Experimental structural studies

Force Measurement

The sensor is designed to estimate the force acting on suspended or rigid
plates mounted against wave action or other external forces. The measured
force can be used to study the response of structures and plates subjected
to underwater loading.

Non-Contact Signal Pickup

The sensor incorporates a non-contact electro-inductive signal pickup.
This arrangement is intended to provide force measurement while maintaining
compatibility with long cables.

Response and Output

The sensor has a response time of less than 0.25 seconds. Its output is
specified as 0 to 5 volts, with a low-impedance circuit for noise-free
operation and compatibility with long cables for displaying data at
distant points.

Construction

The sensor is constructed using high density plastic and stainless steel.
The design is intended for use in underwater experimental measurement
applications.

Cable Configuration

  • Standard Cable Length: 15 metres
  • Long Cable Compatibility: Suitable for long cable
    operation through the low-impedance output circuit
Monitor up to 32 sensor channels simultaneously, with real-time recording, graphical monitoring and wave-data analysis from a single system.
