Description

The ICA miniature load cell amplifier measures just 19mm in diameter and 7.6mm in height and is designed for incorporation into the body of a broad range of strain gauge transducers and load cells.

When space inside the load cell or transducer is restricted, the ICA miniature load cell amplifier can also be mounted in-line on the transducer cable inside a dedicated enclosure suitable for the application environment.  We offer our own compact IP65-rated die cast enclosure the measures just 50mm x 45mm x 30mm which suits most general industrial applications (pictured right).

There are a total of six output variants of the miniature ICA load cell amplifier available:

  • ICA1H: 0.1 to 10Vdc  (13 to 30Vdc supply)
  • ICA2H: 0.1 to 5Vdc  (8.5 to 28Vdc supply)
  • ICA3H: ±10Vdc  (±13 to ±15Vdc bi-polar supply)
  • ICA4H: 4-20mA (3-wire)  (10 to 30Vdc supply)
  • ICA5S: 4-20mA (2-wire)  (7.5 to 30Vdc supply)
  • ICA6H: ±10Vdc  (14 to 18Vdc supply)

We hold stock of all the miniature load cell amplifier models mentioned above for immediate despatch.

The high speed, reliability and clean output of the ICA4H miniature amplifier enabled the data to be analysed immediately after each test.

Submersible Load Cells Lower the Cost of Large Tidal Turbine Designs

close up of tidal turbine test rig

This case study aims to significantly reduce the cost of large scale tidal turbine designs using our submersible load cells. The tidal turbine test rig was placed in a state-of-the-art test tank, where the team were able to increasing the size, flow rate and turbulence levels within the tank. Lowering the cost of rotor blade manufacture would make this renewable energy more economical to use and widely accessible, benefiting not only the UK renewable tidal energy markets but developing tidal energy countries too. Our submersible load cells measured both the torque and the thrust of the underwater tidal turbine design.

Our Shear Pin Load Cells and Draw Wire Sensors Deliver Flawless Results in Sub-Zero Temperatures

Antarctic Deep Ice Core Drilling Application

Applied Measurements were contacted by Victoria University of Wellington to provide reliable and accurate equipment that could operate in the sub-zero temperatures of the Antarctic. Using Applied Measurements’ two customised DBEP shear pin load cells, a WS12 draw wire sensor and four intuitive2 displays, the RICE team were able to successfully extract a 763m deep ice core from an ice cap on Roosevelt Island.
