EXTENSOMETERS
Electrical MPBX
This system is similar to the Mechanical MPBX units, except that this unit has a head assembly with a vibrating wire displacement sensors (the range – 50, 100 or 150 mm). Multi-core cables are used to transmit electrical output over long distances. The readings can be taken with a portable readout unit/data logger or through a remote automatic data acquisition system. This system is also available for use with mechanical readout devices.
