PRODUCT FOCUSLooking for OEM Users of 85-Inch (2159-mm) Range Position Transducers Does Your Application Require More Than 50 Units and 50- to 85-Inches (1270- to 2159-mm) of Displacement Monitoring?
Figure 1 - A preview of the soon-to-be-released Firstmark Controls position transducer for OEM applications requiring displacement monitoring of up to 85 inches (2159 mm). Do you have a current or future OEM application requiring 50 or more units with a displacement monitoring requirement of 50 to 85 inches (1270 to 2159 mm)? Firstmark Controls will soon be releasing an OEM position transducer product line for such applications. If you would like to receive notification of the product line's data sheet release, please complete the form below. APPLICATION NOTEApplication Note Educates on How to Minimize Draw Wire Transducer Error Error Categories Are Assessed to Document Product Performance Engineers can now learn how to produce data that is as accurate as possible with Firstmark Controls's new application note discussing accuracy and precision for draw wire transducers. The application note covers the different ways error can affect sensor data, along with descriptions of specific design features inherent within Firstmark Controls draw wire transducers for minimizing error. The illustrated 7-page Application Note on Draw Wire Transducer Accuracy is available at no cost to readers via the Firstmark Controls website. The document's general review of mechanical and electrical error and sensor-specific functionality provides useful information for engineering and technical audiences. The Application Note for Draw Wire Transducer Accuracy includes:
The application note presents error types by category, such as electrical, mechanical, repeatable, and non-repeatable. Errors are documented through equations, figures, and descriptions. In addition, the document contains links to additional resources for readers wanting to know more about accuracy and error, including error calculators, sensor data sheets, and a complete bibliography. Readers will walk away knowing why the difference between accuracy and precision is critical to data collection, and which types of error are relevant to draw wire transducer applications. The application note makes the information easily accessible to the general audience by establishing top-level theories and information before exploring specific error types. The information contained in the Application Note for Draw Wire Transducer Accuracy can be applied to a variety of sensors such as Firstmark Controls's series of draw wire transducers.

All around you -- up in the sky, on the race track, at building sites, in university research labs, and even in space. With durable construction and a compact body (or, as American BOA, Inc. puts it, "...virtually indestructable...even after fire damage and bouncing off the pavement!"), Firstmark Controls products are used across a wide variety of fields, including aerospace components, heavy machinery, industrial engineering parts, and motorsports. NASCAR race teams find Firstmark Controls position transducers durable enough for tracking data within the intense environment of a car engine bay, even in a worst-case scenerio. When disaster struck and the car crashed into the wall, much of the car's systems and components were destroyed -- but the Firstmark Controls position transducer still worked after intense shock and heat.
Figure B1 - A NASCAR race team put a Firstmark Controls position transducer to a survival test -- and it thrived! Aerospace giant Raytheon put Firstmark Controls's position transducers in a situation typically used for LVDTs. Though the draw-wire system wasn't what the Raytheon team was used to, their results spoke for themselves. "The Firstmark Controls sensor performed far superior to the LVDT in the lateral movement shock test," commented the Raytheon engineer. In the area of university research, data collection must be performed accurately and on a strict budget. Facilities such as University of Massachusetts, University of Illinois, and Carleton University have put Firstmark Controls products to the test -- literally. At Carleton University, the position transducers were one of the keys to creating a successful motion simulator project. As one Carleton engineering student puts it, "Myself and the other project engineers are impressed with the transducers and their functionality." At the University of Massachusetts, researchers were more than pleased with the durability and functionality of their position transducers. One University of Massachusetts researcher even compared them to a piece of art, noting the research team's needs were exceeded with the precise nature of the position transducers. While the positive feedback from Firstmark Controls clients is a testament to the quality of the products, there's an even more important resource that gets high marks: the people of Firstmark Controls. With dedication to customer service, the Firstmark Controls team goes to whatever lengths necessary to fulfill their customer's needs. "The (Firstmark Controls staff) go out of their way to satisfy the customer, way beyond any other company," one NASA Langley research scientist noted. "Firstmark Controls is the best company I have ever dealt with and they have state-of-the-art products."

TECHNICAL FOCUSFree Analog Position Transducer Find Out How to Get a Free Exclusive Analog Position Transducer from Firstmark Controls. There are days when the most sophisticated measuring instruments just can't get the job done. These instances usually require something more precise than an estimate by the human eye, but there's a time crunch involved and it's simply impossible to set up a position transducer to get the data. What's an engineer to do? When these situations occur, there's no need to fret -- all you need is your trusty analog position transducer, more commonly known as a ruler. Firstmark Controls, one of the industry leaders in position transducers, is happy to announce that these analog position transducers, time-tested over centuries of use, can be obtained for free. These analog position transducers have:
