Transducer, a device of great value.


	Transducer! How essential is this device? Welcome to *transducer-the-essential-device.com* where you will find articles highlighting the importance of this amazing device. The invention of the transducer was a revolutionary event. A device for converting one form of energy into another form. Although this could include a variety of other devices and mechanisms...or living things including us. We do convert energy into another form don't we? Of course, I'll leave the rest of that to your imagination. It is intended to mean instruments developed or designed to perform a process or processes of specific application or scientific principle, to a great degree but not limited to the field of electronic industry branching out into instrumentation, control and protection systems. This site will also bring you researches on many instruments and equipment using various transducer systems that are useful tools in accomplishing your domestic, commercial and industrial activities. From within our homes to the car we drive. The elevator we take to get us to the nth floor where we work. The heating or air conditioning systems in the home and many establishments we conduct our businesses in. We can find them in the weighing systems in supermarkets we go to for our daily or weekly shopping. In the jets we take when we fly to our holiday destinations or on business trips, or the gizmos and gadgets we love to use (aah! we'd be lost without them). I could go on and on. It never ceases to amaze me at how these inventions move us forward in so many positive ways. In our day to day endeavors, this device plays an essential role but not limited to the following areas of activity: Measurement and recording of data Display and monitoring of conditions Sensing and detection of media Control and protection of processes You can find all of the above activities in research and development, in the health and medical field, in the manufacture of goods and many others, including our home appliances. From food processing to pharmaceutical plants and laboratories, they form the core components of a quality system. Early in my working life (not too long ago) I was part of maintenance logistic group in the production of food and beverages. One of the many observations I had was a continuous production operation or a breakdown thereof could depend on the seemingly simple but nevertheless effective "thermocouple", which is a temperature transducer. Take your time as you explore the many sections of this site and find what you are looking for. Torque Telemetry It is a way of measuring torque with the use of transducers converting torque energy into a voltage signal. With the application of strain gauge transducers, a signal is transmitted to a receiving module via RF. The same signal is converted into analogue or digital voltage value proportional to torque being measured which is then shown onto a remote display monitor. Thomas Johann Seebeck One of the first to discover thermoelectricity from his experiments, also known as the Seebeck Effect, named in his honor. Born April 9, 1770 in Estonia. He was a physicist who experimented on two electric wires made from different materials. He discovered that when welded together at one end this coupling of wire generated electromotive force (emf) as a result of the difference in temperature between its cold and hot points of connection. In essence, this discovery became the basis or the thermocouple theory behind the use of thermocouples. There are many others like him who ventured into the "unknown" fields of Science and came away with inventions that are the fruits of what we enjoy today. A temperature transducer usually includes a temperature sensor such as RTD (resistance temperature detector), a thermocouple or a thermistor. Upon sensing, it converts temperature into an electrical signal proportional to the same parameter being sensed or measured. This signal will then be processed, conditioned or amplified to serve as an input voltage into a temperature controller or similarly functioning device. Temperature measurement, monitoring and control are vital activities. In certain applications, in the process control industry for example... there is a need to constantly and consistently monitor temperature. Why is this so? Let's take for example milk pasteurization. Fresh milk, generally has a very short shelf life. By means of controlled heat pasteurization also called High Temperature/Short Time (HTST), milk shelf life can be extended up to two weeks provided it is refrigerated. Another process called ultra high temperature (UHT) treatment can extend some beverages shelf life for up to six months or more when packaged aseptically. This sterilization process requires the most reliable temperature instrumentation systems in order to achieve the best result. It is not the intention, however to delve deeper into these manufacturing processes. Suffice it to say that they are examples of how temperature transducers can be applied in the monitoring and control of systems involving temperature. Read the rest of the article here.

Related Articles From The Earth To The Moon And Back -- The Ubiquitous Velocity Transducer The phrase "Shoot The Moon" has many contexts but fundamentally it means "go for it". However, NASA literally did shoot the moon with one stage of Apollo 13. The aim (pardon the pun) was to complete an experiment whose first stage was performed by Pete Conrad and Al Bean during one of their two walks on the lunar surface during the Apollo 12 mission. Conrad and Bean placed a very sensitive device on the ground outside of their LEM which was essentially a seismometer. So well did it function that as soon as Conrad powered the machine on, Mission Control in Houston, Texas was able to read telemetry which detected Conrad's foot falls nearby the device.
