INTRODUCTION This kit comprises six linear displacement transducers. It is the foundation kit for the TK2942 range and introduces some basic principles about transducers and associated instrumentation requirements.

FUNCTION Six linear displacement transducers are provided, each of which mounts onto the Test Rig. This is used to provide transducers displacement, the whole platform being moved to provide large displacements. The following linear transducers are provided;- • Linear Variable Resistor • Variable Area Capacitor • Variable Distance Capacitor • Variable Inductor – with sliding rod carrying a ferrite slug core. • Linear Variable Differential Transformer ( LVDT ) – This is uses a sliding core similar to the Variable Inductor and is used in conjunction with a phase-sensitive rectifier housed in the instrumentation module. • Strain Gauge - In addition to the linear displacement transducers, a Probe Assembly is provided for liquid depth measurement. This is intended to be used in salt water. Variations in depth or salt concentration vary the resistance between the probes. The resistive transducers are used either in a Wheatstone bridge or in the feedback loop of an operational amplifier. The capacitive and inductive transducers are used as frequency determining elements in an oscillator circuit. The inclusion of a discriminator and amplifier in the Instrumentation Module enables complex FM systems to be constructed.4.
