Sensors Used in Instrumentation and Control

Ammeter - A meter to indicate electrical current. It is normally part of a DMM.

Bellows - This is a flexible volume that will expand or contract with a pressure change. This often looks like a cylinder with a large radius (typ. 2") but it is very thin (type 1/4"). It can be set up so that when pressure changes, the dis-placement of one side can be measured to determine pressure.

Bourdon tube - Widely used industrial gage to measure pressure and vacuum. It resembles a crescent moon. When the pressure inside changes the moon shape will tend to straighten out. By measuring the displacement of the tip the pressure can be measured.

Chromatographic instruments - laboratory-type instruments used to analyze chemical compounds and gases.

Inductance-coil pulse generator - transducer used to measure rotational speed. Output is pulse train.

Interferometers - These use the interference of light waves 180 degrees out of phase to determine distances.
Typical sources of the monochromatic light required are lasers.

Linear-Variable-Differential transformer (LVDT) electromechanical transducer used to measure angular or linear displacement. Output is Voltage

Manometer - liquid column gage used widely in industry to measure pressure.

Ohmmeter - meter to indicate electrical resistance.

Optical Pyrometer - device to measure temperature of an object at high temperatures by sensing the brightness of an objects surface.

Orifice Plate - widely used flowmeter to indicate fluid flow rates

Photometric Transducers - a class of transducers used to sense light, including phototubes, photodiodes, phototransistors, and photoconductors.

Piezoelectric Accelerometer - Transducer used to measure vibration. Output is emf.

Pitot Tube - Laboratory device used to measure flow.

Positive displacement Flowmeter - Variety of transducers used to measure flow. Typical output is pulse train.
Potentiometer - instrument used to measure voltage.

Pressure Transducers - A class of transducers used to measure pressure. Typical output is voltage. Operation of the transducer can be based on strain gages or other devices.

Radiation pyrometer - device to measure temperature by sensing the thermal radiation emitted from the object.

Resolver - this device is similar to an incremental encoder, except that it uses coils to generate magnetic fields. This is like a rotary transformer.

Strain Gage - Widely used to indicate torque, force, pressure, and other variables. Output is change in resistance due to strain, which can be converted into voltage.

Thermistor - Also called a resistance thermometer; an instrument used to measure temperature. Operation is based on change in resistance as a function of temperature.

Thermocouple - widely used temperature transducer based on the Seebeck effect, in which a junction of two dissimilar metals emits emf related to temperature.

Turbine Flowmeter - transducer to measure flow rate. Output is pulse train.

Venturi Tube - device used to measure flow rates.

i hope you enjoyed this post, comment me for any clarification.

Spiral bimetallic thermometer

Basic principle of Spiral bimetallic thermometer

When a bimetallic spiral fixed at one end and free at the other end is subjected to a temperature change, the free end of the bimetallic spiral deflects proportional to the change in temperature. This deflection becomes a measure of the change in temperature.

Description of Spiral bimetallic thermometer

construction of Spiral bimetallic thermometerThe main parts of a spiral bimetallic thermometer are as follows:
A bimetallic spiral which is fixed at one end to the body of the instrument and free at its other end.
To the free end of the bimetallic spiral is attached to a free floating shaft.
One end of the shaft is mounted in a fraction less arrangement and its other end is connected to a pointer which sweeps over a temperature calibrated circular dial graduated in degrees of temperature.

Operation of Spiral bimetallic thermometer


image of Spiral bimetallic thermometerWhen a temperature of a medium is to be measured, the bimetallic thermometer is introduced into the medium for a length ‘L’

The bimetallic spiral senses the temperature and expands resulting in a deflection at its free end.

This deflection at the free end of the bimetallic spiral rotates the free floating shaft connected to it. When the free floating shaft rotates, the pointer attached to the shaft moves to a new position on the temperature calibrated dial including the measured temperature.
