Part 1 of this FAQ looked at the basic operation of the LVDT. This part looks at some of its other performance attributes and characteristics. Q: What does an LVDT […]
Frequently Asked Question (FAQ)
LVDT position sensor, Part 1: basics and principles
The linear variable differential transformer (LVDT) is a widely used, inherently rugged, linear-position sensor offering accurate and consistent performance over a wide span of distances. Sensing of physical position is among the most commonly needed parameters in industrial, military/aerospace, robotics, scientific measurement, and control applications, and there are many sensors in use to accomplish this. […]
How can engineered substrates accelerate sensor designs?
Silicon on insulator (SOI) substrates are the starting point for fabricating many sensors. One company offering a portfolio of advanced engineered substrates presents an interesting design alternative to customers. IceMOS Technology Ltd of Belfast Northern Ireland has a very attractive alternative to unprocessed starting wafers. Outsourced engineered substrates enable a company to expand their MEMS […]
What can sensor companies do to cope with the new normal of COVID-19?
With the ongoing impact of Covid-19, its re-emergence in many regions and travel significantly affecting many companies, changes in some normal activities must be considered. According to Roger Grace, President of Roger Grace Associates, a MEMS and sensors industry marketing consultancy, marketers need to consider “pivoting” their marketing strategies and need to objectively assess what […]
How can printed sensors help prevent the spread of COVID-19?
In addition to wearing a mask and frequently washing your hands, social distancing provides the third leg of the COVID-19 prevention stool. Unlike in public settings, private companies have their own interest to ensure their employees and other customers are safe and social distancing is an undisputed deterrent for the virus. In fact, recent research […]
What is the secret sauce for wearables?
First, let’s consider the usual suspects: Type of sensor or sensors used: accelerometer, barometer, magnetometer, gyroscope and more Type of power source: battery, rechargeable battery, energy harvesting Other electronics to compute, store and conserve power consumption and more What the wearable does – measures and then communicates: activity tracker, electrocardiogram (ECG), fall detection, compass and […]
How is self-powered clothing doing?
If you’re interested in the information and convenience that a wearable product can provide, you probably do not want to worry about how it gets its energy or when recharging is required and certainly do not want to change batteries. You just want to get uninterrupted information. One company built on offering invisible wearables has […]
How can sensing be used to protect attendees at an indoor convention?
For the Royal International Miss 2020 Pageant, plans were in the making for several months and in spite of the COVID-19 virus, the state OK’d the convention and the hotel made every effort to ensure the safety of attendees. To avoid a person with the virus from entering the hotel and infecting attendees, a temperature […]
What does sensing above and sensing below look like?
This question certainly raises another, why do I need both? The answer to these questions starts with the goal of conserving water. The smart use of water to improve soil quality, especially in agronomic applications, requires optimal use of this precious resource. In-ground sensing has been used for many years and even enhanced with wireless […]
How can you get 5 different pressure sensor ranges from a single sensor?
Heating ventilation and air conditioning (HVAC) applications can use a wide range of full-scale, low-pressure sensors to address the variety of measurements involved in controlling and monitoring for maximum efficiency and performance. In a multilevel building, these measurements could include the use of differential pressure transmitters, a variable airflow volume (VAV) unit, a positive pressure […]
