  Barocaloric materials have shown to be promising alternatives to the
conventional vapor-compression refrigeration technologies. Nevertheless,
barocaloric effect ({\sigma}b-CE) has not been extensively examined for many
classes of materials up to now. Aiming at fulfilling this gap, this paper
describes the development of a high-pressure experimental setup for measuring
the {\sigma}b-CE in polymers. The design allows simultaneous measurements of
temperature, pressure and strain during the barocaloric cycle. The system
proved to be fully-functional through basic experiments using natural rubber.
Samples exhibited large temperature variations associated to the {\sigma}b-CE.
Strain-temperature curves were also obtained, which could allow indirect
measurements of the isothermal entropy change.
