 Crude Petroleum dan Residual Fuel Oil – Tank Sampling tidak dianjurkan, karena pada umumnya material tersebut tidak homogen. – Sangat dianjurkan dengan Automatic Sampling ASTM D 4177  Gasoline dan Distillate Product – Material tersebut umumnya bersifat homogen – Dapat dilakukan Tank Sampling Instruksi Khusus untuk Pengujian Khusus 1. Distilasi ASTM D 86 – teknik yang dianjurkan adalah prosedur ...

• Pressure and force transducers (load cell – consists of elastic material and displacement sensors – measure quantity (i) strain or (ii) displacement – grouping: absolute gauge and differential types Figure 3.51 Diaphragm pressure sensor: (a) flat-type diaphragm, (b) corrugated diaphragm, (c) media of capacitance • pressure sensor with diaphragm reliable, difficult to make, reproducible – measure strain with strain ...

 Crude Petroleum and Residual Fuel Oil – Tank Sampling is not recommended, because in general the material is not homogeneous. – Highly recommended by the Automatic Sampling ASTM D 4177  Gasoline and Distillate Product – These materials are generally homogenous – Can be done Tank Sampling Special Instructions for Special Tests 1. Distillation ASTM D 86 – The ...

– detect position through code by reflector or by passing light transmission to photo detector – displacement (relative) is measured in the form of a pulse train with a frequency equal to the speed of movement Figure 3.33 Optical digital position sensor: (a) and (b) rotary shift, TX-RX parallel, (c) and (d) horizontal shift, TX-RX forming angle. – motion detection ...

The most commonly used sensor for angular velocity sensors is the tacho generator. Tacho generator is a small generator that generates DC voltage or AC voltage. In terms of excitation tacho generator can be generated with excitation from the outside or electromagnetic impact of permanent magnet. Tacho DC generator can generate DC voltage which can directly generate speed information, tacho ...

Potentiometers available on the market consist of several types, namely: carbon potentiometer, wire wound potentiometer and film metal potentiometer. 1. Potentiometer of carbon is a potentiometer made of carbon materials the price is quite cheap but this potentiometer kepressian very low usually the price of resistance will be very easily changed due to contact shift. 2. Wire wound potentiometer is ...
