This question addresses VSWR (Voltage Standing Wave Ratio) and Return Loss, which are both a measure of the same parameter. That is, the amount of signal reflected by a connector. It is the major factor contributing to the total signal efficiency of the connector.

Fig. 3 shows the measured position of a magnetostrictive sensor during a vibration of 30 g for the frequency spectrum of 10...2000 Hz. The vibration causes the reference point and thus the measured position to fluctuate. Depending on the frequency, these position changes vary in magnitude. However, the sensor is not damaged by the

Hygrometers can be used to measure the output of the dehumidifier to make sure the %RH levels or other psychometric readings are moving in the right direction. Along with moisture meter readings, hygrometer measurements provide proof that a space’s ambient conditions are brought back to a pre-loss state.

Typical input/output power supplies will block this DC bias voltage at the output via a blocking capacitor in order to AC couple the signal to readout devices. By "teeing" off the input into a DC volt meter, the bias voltage can be measured. While measuring the supply voltage, the bias voltage can be measured after the sensor is plugged in.

Keying - Mechanical arrangement of guide pins and sockets, keying plugs, contacts, bosses, slots, keyways, inserts or grooves in a connector housing, shell or insert that allows connectors of the same size and type to be lined up without the danger of making a wrong connection. Lanyard - A device attached to certain connectors that permit uncoupling and separation of connector halves by a pull ...

For industries operating in high-risk environments, selecting cables with the proper cold ratings is a critical safety measure. Operational Limits at Low Temperatures . The Cold Temperature Rating measures the lowest temperature at which a cable can function optimally. In freezing conditions, certain materials can become brittle, leading to a ...

Sensor data is directly measured and digitized on a rotating shaft then transmitted off-shaft using wireless technology. The receiver outputs high bandwidth analog data. These systems are ideal for taking precise measurements for torque, strain, temperature (RTD) and voltage on drive shafts of motor-generator field excitation.

From this point the angular displacement is measured ending at the final torque level. This angle measurement is known as the clamp angle. This plot is referred to as the M-Alpha diagram. The clamp angle from Figure 6 is measured to be 85 degrees. From Figure 4 the tension is known as 7500 lb (33.4 kN) at 60 lb-ft (81 N-m).

Fiber Undercut (or Protrusion) is measured in one of two approaches -- planar or spherical. The planar method has all but been abandoned by the industry, and it is derived from defining the location of the inside of the ferrule where the fiber passage way stops inside at the end. A virtual planar surface would be

Cable glands are an essential component of any electrical installation, and understanding the different types of thread used in cable glands is important. The three most common types of threads used in cable glands are NPT, Metric, and PG. Understanding the differences between these thread types will help you choose the right cable gland for your needs.

measure or compensate for errors due to extraneous loads. If the presence of these extraneous loads is known, the user should request the transducer manufacturer to run a special test at extra cost to define and quantify the extraneous load errors. These errors are defined as cross-talk errors. Typical Application Examples • Hydraulic Actuators

If using a microphone to measure the noise, or the 1% THD value of a speaker, headphone, or instrument, and the microphone has a high level of inherent distortion, the design engineer for the speaker or instrument will not be able to accurately confirm that the distortion stems from the product they are developing rather than the instrument ...

measured using data outside the calibrated range of the accelerometer, and is thus not traceable. This adds another level of complexity not only in trying set vibration standards or limits for HFE measurements but also in trying to compare results. ∞ Displacement is used to measure very low frequency faults such as unbalance in slow speed

Moisture levels inside a building and its materials can be measured in many ways. But which are the most accurate and representative of actual moisture content values in a space?. Our How to Measure Moisture in Buildings guide takes you through exactly what you need to know to collect & interpret moisture readings you can be confident in.. We cover key elements of evaluating moisture presence ...

These have led to a surge in the number of parameters used in AI models, which can be seen as a measure of their complexity and capacity to learn. For example, the Transformer model [1] with 465 million parameters in 2019, and the Gshard MoE model [2] with over a trillion parameters in mid-2020, highlight the rapid growth in model size.

couple and measure high frequency signals. Permanent mounting: Threaded stud, cementing pad Cementing pads approach the capabilities of stud mounts when used properly. The following are recommended permanent mounting procedures. Alternative procedures should be evaluated with respect to frequency response, grounding, and installation requirements.

develop blast pressure transducers to measure static overpressure. Much of this research was focused on: (1) “pencil” probes (or gages) and (2) “pancake” or “lolly-pop” gages. Both types were designed to measure at locations above ground level. The latter gage, shown in Fig. 1, has
