Alliance Sensors Group
Alliance Sensors Group has developed into “The Name in LVDT Signal Conditioning” due to the constant improvements and advancements made to its line of LVDT signal conditioners.
Alliance Sensors Group was founded by Harold and Howard Schaevitz, widely known as the first family of LVDTs.
The Schaevitz family has chartered Alliance Sensors Group not only to develop specialized LVDT products, but also to work and partner with other LVDT manufacturers to develop the top grade LVDT signal conditioning products that could advance their application solutions as well
They specialize in Industrial, OEM, Power Generation, Military, Test Labs and Special Processes in Manufacturing.
Their product line includes LVDT, LVIT position sensors, RVIT rotary sensors, support electronics and a range of special sensors.

S1A and SC-100
The S1A and SC-100 DIN-rail-mounted, push-button-calibrated LVDT signal conditioners were developed by listening to customers and LVDT manufacturers’ comments and wish list. This has allowed Alliance Sensors Group to design and build signal conditioners that work with all different types of LVDTs, LVRTs, GE “buck-boost” LVDTs for gas turbines, half-bridge pencil gaging probes, and RVDTs, rather than only satisfying markets where they are strong and not addressing the concerns of LVDT users with other applications.
The number one question from the marketplace was “Can you reduce the set up and calibration time?“
Solution: S1A and SC-100 LVDT Signal Conditioners offer smart and fast LVDT setup with built-in null indication and simple front panel pushbuttons to set zero and full scale. Calibration time is now reduced from at least 20 minutes per channel to just a minute or two.
These industrial type sensors can withstand added physical strength and heat resistance due to their superior materials.
They also feature protection up to IP 68.

Alliance Sensors Group draws upon a wealth of design engineering. It has an applications engineering team with over 150 years of combined experience in the position sensor and measurement instrumentation fields

“When we looked at what the market was offering, we knew we could do better. We contacted many customers and friends in the LVDT manufacturing world to get their inputs. This allowed Alliance Sensors to offer the very best signal conditioners in the industrial market and gives us ongoing feedback about the performance of these conditioners and improvements we could make,” says Harold Schaevitz, President of Alliance Sensors Group.
Besides the S1A and SC-100 signal conditioners, Alliance Sensor Group also offers a line of heavy duty LVDTs for power plants, industrial manufacturing, and process control applications.

“This isn’t your grandfather’s LVDT”
MOORESTOWN, N.J.—February 1, 2013 Alliance Sensors Group is pleased to announce the new LA-25 series LVDTs for use in steel, aluminum, and paper mills as well as in fluid power systems and hydro plants.
An LA-25 is not your grandfather’s LVDT. It is very robust and designed to survive heavy duty applications in harsh environments. Typical LVDTs offered to the heavy industrial marketplace are 0.75 inches in diameter with lead wires.
This robust linear position sensor has a 1.00 inch OD aluminum housing (stainless steel housings are available) with a wall nearly 5 times as thick as typical LVDTs, and terminated with either a cable in a cord grip or heavy duty axial connector. The durability of its housing protects an LA-25 sensor from damage when stepped on or having material dropped on it. The LVDT’s housing has a threaded end nose that can go through a 0.88 hole in a bulkhead or bracket up to 0.13 thick, permitting single hole mounting using an optional mounting kit containing a hex nut and lock washer.
Other LVDTs are offered with a 0.188 inch OD core that is not usually captive to the LVDT body and can easily be lost, damaged, or broken loose from its mating rod.
An LA-25 LVDT’s core is enclosed inside a 0.375 diameter stainless steel connecting rod assembly from which it can never break loose, and which moves within a bronze bushing equipped with two double contact shaft seals to keep out dust, dirt, and fluids. The rod has a 5/16-24 UNF male threaded end for connection of the user’s workpiece or optional end pieces available from Alliance Sensors. A radially-terminated version with rod ends attached to the core rod and the back end of the sensor is also available.
