Differential Capacitance Pressure Sensor Circuit
An ingenious circuit used to generate an electrical voltage signal from a differential capacitance pressure sensor is the Twin-T diode circuit, shown here connected to a Rosemount-style differential capacitance pressure…
Pressure Transmitter using Potentiometer and Diaphragm
Shown here is a very simple pressure transmitter, a device that measures a fluid pressure and converts that measurement into an electrical signal: Suppose the potentiometer wiper will be at…
Indentify Faults in Simple Lamp Circuit including Failed Wires
Suppose the lamp refuses to light up. A voltmeter registers 24 volts between test points C and D: Simple Lamp Circuit First, list all the possible (single) faults that could…
Differential Pressure Measurement across Baghouse
Suppose a differential pressure transmitter is used to measure the pressure dropped across a baghouse, an assembly using multiple fabric “socks” to filter particulate material from a gas stream, like…
