Practical No. 1 Identify contact and Non-Contact Type Instruments

MEM (22443) Manual Answers Practical No 1

A practical Significance

The transducer is a device that converts one form of energy into another Electrical to Mechanical, Mechanical to Electrical. Thermal to Electrical and etc. The emphasis in the instrumentation trainers will be directed toward electronic instrumentation systems miner than mechanical systems. In most cases, electronic systems provide better data and more accurately and completely characterize the design or process being experimentally evaluated. Also, the electronic system provides an electrical output signal that can be used for automatic data redaction or for the control of the process

Minimum Theoretical Background

Measuring Instruments are basically classified into

1. Contact Type-A contact type instruments are those which make physical contact with the object to be measured

2. Non-Contact Type- These instruments are those which do not make any physical contact with the object to be measured
