The LS18 Slimline Short Stoke Linear Position Sensor has been specifically designed for industrial and scientific applications that require a narrow bodied and short in length, position sensor. What visually sets it apart from LS01 and LS17 is the sturdy two 3.2mm by 30 degree wide mounting flange, available on the radial configuration of the sensor. Exquisitely engineered, the 19mm diameter body of the sensor is constructed from stainless steel and when combined with the non-wearing inductive technology, will deliver dependable performance for many years.
The non-wearing inductive technology used in the LS18 is a major advance in displacement sensor design. This transducer has the simplicity of a potentiometer with the life of an LVDT. The LS18 sensor outputs a stable DC analogue signal by using simple inductive coils in conjunction with advanced ASIC control technology. As there is no contact between moving electrical components, reliability is high and wear is eliminated for an exceptionally long life. It also overcomes the drawbacks of LVDT technology that typically include; bulky coils, poor length-to-stroke ratios, separate signal conditioning requirements and the need for special magnetic materials.
The LS18 provides a linear output proportional to travel. Each unit is supplied with the output calibrated to the travel required by the customer, any stroke from 0-2mm to 0-50mm can be specified during the order process. The default accuracy of the LS18 is 0.25% FSO, however if you would like a greater accuracy of 0.1% FSO, for stroke ranges above 10mm, then this can be specified during the ordering process too.
The sensor is very robust, the body and push rod being made of stainless steel for long service life and environmental resistance. It is particularly suitable for OEMs seeking good sensor performance for arduous applications such as industrial machinery where cost and reliability is important.
Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is easy to install with mounting options including M5 rod eye bearings and body clamps. The push rod by default is supplied, free or captive, with female M4x0.7×7 deep thread. Alternatively, M5 rod eye, dome end and magnetic tip options are available too. The LS18 also offers a wide range of mechanical and electrical options and is IP67 rated. The ability for the LS18 to remain unaffected by external Electrical Magnetic interference is assured by the built in EMC protection that conforms to EN 61000-6-2 and EN 61000-6-3 standards.
Common applications for the Applied Measurements LS18 position sensor include geotechnical testing, R&D, aerospace, civil engineering and automotive.
Applied Measurements can supply a wide variety of instrumentation to complement your LS18 position sensor, such as wireless transmitters and receivers, digital displays and amplifiers.
