The Vibrator

Chemical reactions go faster at a controlled temperature and in the presence of some vibration, which helps to mix reagents. A legacy design used a small motor vibrator as found in silent pagers and mobile phones. This allowed some frequency variation but the amplitude could not be independently controlled.

Our customer commissioned a moving armature device which worked over the desired frequency range. We designed and built an efficient circuit to drive the actuator with independent control of frequency and amplitude. This is what the final product looks like.

TTL To Opto Converter

A connector manufacturer needed to extend a communication signal over a long distance in an installation where there could be removable equipment and several connectors in the path. The transmitted and received signals were TTL based and the long connection was to be an optical fibre. In the short term, they needed some prototypes to be designed and made to prove the concept.

Loop-Powered Current Shunt Amplifier

A customer needed to monitor the current flow from a sacrificial anode used for corrosion protection within a desalination plant. The electronics were mounted inside the impressive 300 mm diameter explosion-proof enclosure shown here.

Rugged Electronics

TRL operates a test facility which involves a fast-moving sledge that is very quickly decelerated at a known rate. As it reaches the point just prior to the deceleration, a strobe is fired which must start a datalogger and simultaneously trigger several large photoflash lamps. The customer needed additional trigger units with the same form as an existing stripboard based device to put on new sleds so that they could improve the turnaround time for better use of the facility.
