Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

A frequent beginner project involves measuring soil moisture levels by measuring its resistance with a couple of electrodes. These electrodes are available ready-made as PCBs, but suffer badly from ...

This paper describes the design and characterisation of a long-range capacitive displacement sensor, NanoSensor® model NXE2. Special emphasis is placed on the design features and metrological ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

Viable cell count (VCC), a critical parameter in both microbial and mammalian cell cultures, fluctuates during batch and fed-batch cultures. VCC is determined conventionally through sampling and ...

The report "Humidity Sensor Market by Type (Capacitive, Resistive, Thermal Conductivity, Optical, Carbon, Ceramic, Lithium ...

The project illustrates the design of an accurate water level sensor that is comprised of capacitance probe, analog electronics unit, and digital electronics unit. The project illustrates the design ...

Soil moisture profile measurements are an integral component of water balance estimation networks, especially in thick vadose zones and fine-grained soil environments. At field sites with silty and ...

The cable’s capacitance adds to the scope’s input capacitance and shunts the scope’s 1-M? input resistance, resulting in a time constant of approximately 100 µs. Such a severe low-pass filter begins ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

Making accurate, high-speed time domain measurements does not have to be a challenge. Employing a few tips can greatly simplify the task. When choosing the oscilloscope and probe for high-speed ...
