DC Inputs
DC Inputs: The, dc inputs modules commonly available will work with 5, 12, 24 and 48 volts. The DC Inputs modules allow us to connect either PNP (sourcing) or NPN (sinking)…

Second Order High Pass Butterworth Filter Derivation: As in the case of a first order filter, a second order high pass filter can be formed from a second order low…
Diode Bridge Type Modulator with Transformer Coupling: Diode Bridge Type Modulator - Figure 14.33 shows a silicon diode ring modulator with an associated ac coupled dc amplifier. The amplifier itself…
Measurements of Thickness using Beta Gauge: Beta Gauge - A common and characteristic feature of a radioactive element is that they disintegrate spontaneously to produce fresh radioactive elements called daughter…
Photoelectric Transducer Working Principle: Photoelectric Transducer can be categorized as photo emissive, photo-conductive or photo-voltaic. In photo emissive devices, radiation falling on a cathode causes electrons to be emitted from…
Null Type Recorder: These Null Type Recorder Working Principle of self-balancing or null conditions. When an input is given to the measuring circuit of the recorder from a sensor or transducer,…
Bridge Controlled Error Detection: Bridge Controlled Error Detection - Whenever a bridge is unbalanced, a potential difference exists at its output terminal. The potential difference causes current to flow through…
Megger Circuit Diagram: Another common method of measuring resistances above 50 M Ω is the Megger Circuit Diagram (megaohmmeter) shown in Fig. 10.23(a). This instrument is used to measure very…
