What is Thermal Hysteresis? Thermal hysteresis is the difference between two identical pressure readings taken at the same temperature point where the first is taken with an increasing temperature value and the second with a decreasing temperature value.…
Typical applications Applications such as those in autoclaves and manufacturing processes that involve curing a material can be challenging for pressure sensors. These applications may involve large changes of pressure and temperature. Changes in pressur…
What is long term stability of pressure sensors? Long term stability is a change in output, either zero and/or span, at two successive points in time under the same conditions. This change in output is not directly attributable to any other effect at the…
The majority of pressure sensor designs that are used in industrial applications have some form of mechanical isolation diaphragm that protects the sensor element from the pressure media. In order to translate the pressure effectively to the sensor eleme…
Customer: Aviation maintenance operator Application: 14 CFR 91-411 testing Products supplied: Druck ADTS 553F & VIAVI AVX-10K-CNS
Sensor signals in the form of a 4 to 20mA current loop are commonplace in industrial systems. Devices using this form of signal output are referred to as transmitters. The current loop signal has the advantages of noise immunity, very long cable lengths,…
What is Torque Sensitivity? Why and when is it important? What is Torque Sensitivity? When torqueing a pressure sensor into a fitting, stress forces resulting from hoop stress may be experienced across the sensing diaphragm of the pressure sensor. Sensor…
What is Pulse Power Excitation Supplying excitation power to a sensor for a brief period of time, a pulse, long enough to take a reading and then switching off the supply is defined, for this discussion, as pulse powering. Where and why would this need t…
What is Soak Back? Soak back occurs when an object or device under test releases heat, either of its own accord, or due to removal of a cooling medium. Common examples include automotive engine compartments, areas within close proximity to braking system…
