An LVDT transformer is exited with a fixed frequency sine wave. The distance of displacement of the movable core will change the amplitude of the transformer output which is is converted to a dc voltage by the LT1967 True RMS converter. The direction of the core movement is indicated by the phase shift of the sine wave and is detected by a simple phase comparator circuit.

Data Acquisition Systems
With the speed and accuracy of modern data acquisitiion devices, it is easy to overlook the need for signal conditioning. While plug-in DAQ devices specifically and accurately measure voltage signals, voltage is one of many I/O types required by modern measurement and automation applications. Many current data acquisition systems must also measure signals from sensors that detect physical, chemical, or mechanical phenomena. While several of these sensors, such as RTD’s, strain gages, piezoelectrical sensors must have signal conditioning to return any measurement, they all require conditioning to return accurate measurements.

While data acquisition devices have become progressively more inticate, the basic principles of data acquisition remain the same – you must connect to the signal, apply the necessary signal conditioning, digitize the signal. With this in mind, the three trival components of all data acquisition systems are:
- SIGNAL CONDITIONING (to condition the signal / sensor)
- DATA ACQUISITION DEVICE (to digitize the conditioned signal)
- SOFTWARE (to analyse, record, and display the acquired signal data)

Process Control is a fundamental topic in all of the main branches of engineering, namely, Mechanical, Chemical and Civil Engineering, and is applicable to virtually all manufacturing and processing industries. For this reason it is essential that all engineering students are taught about the principles of Process Control.

Following response from customers, Armfield has introduced a comprehensive range of products designed to do just that, introducing the fundamental principles. Process Control is a practical subject, so exercises performed by students using laboratory equipment, is the most effective way of imparting a thorough understanding of the topic. Testing the stability of control loops on different processes clearly demonstrates at first-hand the importance of optimising the control parameters and the problems that can be associated with instability, time delays, etc.

The ‘Essentials of Process Control’ (EPC) range features easy to use, highly visual and self-contained products, including PC software, ensuring that students have a clear understanding of the principles, yet the exercises are advanced enough to provide students with a thorough grounding in Process Control.

As with the more sophisticated Armfield Process Control teaching equipment such as the PCT40 Basic Process Control System, the processes and controllers in the EPC range all have the ability to provide repeatable but variable disturbances to the process. This allows the control parameters to be tested, compared and optimised to suit a particular process configuration.

Products within the ‘Essentials of Process Control’ series include PCT50 Level Control, PCT51 Flow Control, PCT52 Temperature Control, PCT53 Pressure Control, PCT54 Industrial PID Controller, PCT55 Programmable Logic Controller, and PCT56 Sensor Conditioning and Calibration Trainer. In addition, PCT54 Industrial PID Controller can be used as a general purpose PID controller, and PCT 55 Programmable Logic Controller can be used to control other items.

For more information on each of these new products, please download the datasheet at www.discoverarmfield.co.uk/data/pct50.

Op-amp adalah rangkaian yang mampu mendeteksi serta memperkuat sinyal baik DC maupun AC dengan penguatan yang mendekati ideal. Rangkaian ini dibangun atas elemen-elemen transistor,resistor dan kapasitor. Op-amp memerlukan catu daya positif dan negative.Sinyal tegangan input dapat dikenakan pada terminal inverting dan atau noninverting.

Hubungan antara Vout dan Vin pada Penguat inverting dan noninverting

• Untuk Inverting Amplifier

  

• Untuk Noninverting Amplifier

Op-Amp sebagai comparator

Prinsip kerja dari komparator adalah sebagai pembanding antara dua inputan dengan salah satu inputan dipakai sebagai acuan /referensi.

• Apabila tegangan inputan lebih besar dari tegangan referensi (misal tegangan referensi di terminal inverting), maka nilai output op-amp akan menjadi High ( sebesar nilai +Vcc, jika +Vcc= 5V, maka outputannya sebesar 5Volt).

• Apabila tegangan inputan lebih kecil dari tegangan referensi tadi, maka op-amp akan mengeluarkan tegangan Low (-Vcc) jika –Vcc =0 V maka outputannya adalah nol Volt.
