Fundamentals of Torque- tension and Coefficient of Friction Testing - PCB
The pitch torque is calculated by the following equation: The thread friction torque is then calculated by subtracting the pitch torque from the thread torque.
UNDERSTANDING TORQUE-ANGLE SIGNATURES OF BOLTED JOINTS - PCB
Torque-angle curve analysis is known to be one of the most basic and practical methods of determining not only what the fastener went through during the tightening process, but also the integrity of the joint itself.

FASTENER TESTING SYSTEMS - PCB
The study of the slope of the torque-angle curve when the fastener is tightened is an important component of analyzing the performance of threaded fasteners in bolted joints.
Return Loss to VSWR Conversion Chart - Amphenol RF
Due to mismatches in impedance within the connector, some of the signal is reflected. The ratio of the input to the reflected signal is called the Voltage Standing Wave Ratio (VSWR). This ratio can also be measured in dB, and expressed as Return Loss.

CFIT: Removal of Bulkhead Door - charlesindustries.com
Press the screwdriver into the hinge slot to release the locking tab at the bottom of the hinge. Support the door from the middle as you lift the hinge partway out of the hinge slot. Release the second hinge tab and lift the door out of the slots.
MEMS Shock Accelerometers - PCB
For MEMS (Micro-Electro-Mechanical-Systems) piezoresistive (PR) shock accelerometers, the two main cable concerns are signal modification due to: (1) additive triboelectric noise generated within the cables and/or (2) unknown or unaccounted for electrical impedance characteristics of the cable.
PCB LOAD & TORQUE: A PCB GROUP COMPANY Load Cell Handbook
Strain gage load cells are the most common and are defined as a device that converts a force or load into an equivalent electrical signal or digitized load value. Strain gage load cells are designed for precisely measuring a static weight or quasi-dynamic load or force.
Understanding Torque-angle Signatures of Bolted Joints - PCB
Torque-angle curve analysis is known to be one of the most basic and practical methods of determining not only what the fastener went through during the tightening process, but also the integrity of the joint itself.
Selecting Accelerometers for and Assessing Data from Mechanical ... - PCB
The various curves in Figure 7 represent different values of damping. These curves are normalized to the natural frequency ω n: (r(ω) = ω/ω n). For low damping values, the natural and resonant frequencies may be considered synonymous. For a shock accelerometer to have a high natural frequency (ω n = (k/m) 1⁄ 2), and, as a byproduct, a broad
TN-25 How High in Frequency Are Accelerometer Measurements Meaningful - PCB
curve is the most probable response of the Model 3991 and the actual test data (blue scatter) contains uncertainty due to its low signal output. Thus, frequency-response determinations become further complicated by low signal levels from the accelerometer under test. This provides additional credibility for limiting the performance
Signal Conditioning Basics | PCB Piezotronics
The solid curve represents the input to the internal electronics of a typical ICP ® sensor, while shaded curves represent the output signals for two different supply voltages. In the negative direction, the voltage swing is typically limited by a 2 VDC lower limit.
Accelerometer Shock Sensitivity Calibration Using a Pneumatic Exciter - PCB
The shape of the curve is as important as the duration. Comparison shock alibration has the least c uncertainty if the waveforms of the standard and SUT are equivalent in shape with no discernable higher-order frequency components, and that the shape is approximately a half-sine yet with no abrupt changes of
