Low frequency machinery monitoring: measurement considerations
Low frequency monitoring of industrial machinery requires specialized sensors, instrumentation and measurement techniques. The primary goal when measuring low frequency vibrations is to minimize electronic noise from the sensor and monitoring instrument.
General Signal Conditioning Guide - PCB
According to the law of electrostatics (Equations 1 and 2), sensing elements with a low capacitance will have a high voltage sensitivity. This explains why low-capacitance quartz sensors are used
Thermopile IR Detectors and Their Uses
thermopile radiation sensor develops a voltage output in response to incoming radiation. The device is a series connection of many thermocouple junctions arranged so that incoming radiation heats a group of detecting junctions while not heating a group of reference junctions.

following equation: A deviation must be added to the resistance tolerance of the part as specified at †
TN-21 Introduction to Air Blast Measurements - Part IV
In Parts I, II and III of this series, we provided an understanding of the air blast environment and the operation of transducers intended to measure it. We went on to describe how to mount these transducers to optimize their dynamic response and how to validate the resultant signal output from the transducers.
Device parameters for Wilcoxon’s intrinsically safe certified sensors
Safety barriers used with hazardous area accelerometer installations typically have five parameters of concern associated with them: voltage, current, power, capacitance, and inductance. The open-circuit voltage available at the terminals of the barrier is Voc. The short-circuit current that the barrier can sink is Isc.
Thermometrics NTC Sensor Linearization - Amphenol
The resistance / temperature characteristics of an NTC based temperature sensor generally are defined by a 4th order polynomial equation and represented by a typical R/T curve. A general R/T is shown for the 0703-1272-76-S1 thermistor as a response to temperature.
General Signal Conditioning Guide - PCB
According to the law of electrostatics (Equations 1 and 2), sensing elements with a low capacitance will have a high voltage sensitivity. This explains why low-capacitance quartz sensors are used predominantly in voltage systems.
Signal Conditioning Basics | PCB Piezotronics
The open circuit (e.g., cable disconnected) voltage sensitivity V1 (Volts per psi, lb or g) of the charge output sensor can be represented mathematically by Equation 1.
IMPACT AND DROP TESTING - PCB
Using the final velocity calculated from the conversation of energy Equation 1, v = √2gh, we may compute the resulting impact acceleration. This acceleration term is dependent on the pulse width of the force-time curve and must therefore take on an estimated value based on various material types, similar to the way impact distance was estimated.

Installation guide for hazardous areas - Wilcoxon Sensing Technologies
The fire triangle is a tool to illustrate the three elements which must be present to have a fire or explosion: fuel, oxidizer, and energy. Fuel and oxidizer must be present in a concentration appropriate to form a combustible mixture. The ignition source must supply enough energy to initiate combustion.
Smart methodologies of monitoring reciprocating compressors - PCB
There are several reciprocating machinery faults which do not significantly increase a machine’s overall vibration level until damage has reached a severe level, including: This paper describes improved shock monitoring methodologies especially suited to effective vibration monitoring of reciprocating machines for fault diagnosis at an early stage.
