Miniature Pressure Sensors.
TML have introduced to their range of strain gauge pressure
transducers, some very small sensors designed for various
modelling tests. They are available in 5 ranges and in two
different designs, with the picture showing the vertical mount
The sensors come in ranges from 200kPa up to 3Mpa full scale,
and have an integral 4-core 1m cable, for connection to standard
strain gauge amplification systems.
The PDA model is a flat disc, 6.5mm diameter and 1 to 1.4 mm thick,
with a side entry cable offering a very low profile pressure measurement.
The PDB has the same disc size, but with a vertical mount cable. Both
can be used safely immersed in water. The rated output is about
1mV/V with a bridge resistance of 350 Ohms.
These sensors are included amongst TML's Civil Engineering
transducer range, which includes several special designs for pore
pressure, inclination, crack opening measurements, and ground
movement. Full size soil pressure measurement transducers are
also available, and all these are shown in the TML Civil Engineering
Transducers catalogue, which is freely available from Techni Measure.
