Footemeter
Compression Frame Stability Tester
Introduction
Description
Originally designed at the BCA, strain
cylinders evaluate the performance of
compression load frames used for
testing concrete cubes ( using the
Foote Meter) and cement mortar cubes
(using the Mini Strain Cylinder).
The equipment comprises a steel
strain cylinder of appropriate capacity
fitted with four balanced strain gauge
bridges. Each bridge is central at one
of the ends of a pair of orthogonal
diameters and is designed to be
monitored by a separate panel meter.
Digital recording meter for
strain cylinders
The digital recording meter is designed
for use with both the Maxi and the Mini
Strain Cylinder. Four LCD meters
monitor the strain gauge bridges on the
strain cylinder. An illuminated push
switch is provided to 'freeze' the display
when the desired load is applied to the
strain cylinder.
Software
Software is provided for analysing the
data obtained during the test.
This is in the form of :
a) a 3.5inch Disk for IBM compatible PCs
or
b) a RAMPACK for a PSION Organiser.
Both software packages calculate the
required strain ratios.
Specification
Recording meter - four LCD panel
meters with freeze facility, calibration
facility and zero adjustment.
220 / 240 v 50 Hz
110 v 50 Hz
Length : Maxi = 200 mm and Min = 20 mm
Diameter : Maxi = 100 mm and Min = 10 mm
Offset from centre : Maxi = 6mm and Min = 2 mm
Load capacity : Maxi = 2000 kN and Min = 80 kN
Data Recording Facility
The digital recording meter is also
available with an inbuilt data logger,
which stores all the readings for
subsequent down loading to ~an IBM
compatible PC. Software is supplied
which transfers the data using the
RS232 serial port. This data is then
analysed using the software detailed
above .
