CPL490 Picometer Capacitive Displacement Sensor
St. Paul, Minn (PRWEB) November 13, 2014
New, larger measurement ranges have been added to Lion Precision’s CPL490 Capacitive Displacement Sensor – the world’s most precise capacitive measurement instrument. Customer demand for larger selection of measurement ranges with very high resolution inspired the creation of new 50 µm and 200 µm measurement ranges. “There are so many applications for super-high precision displacement measurement, that there is always demand for more options. As a company dedicated to working with our customers to create optimized sensing solutions, we work hard at being responsive to that demand,” according to president Don Martin. The new measurement ranges are available immediately.
The CPL490 measures position/displacement with 50 picometer precision or less. Relative to the noncontact sensor’s measurement range, that translates to a resolution value of less then seven parts-per-million even at 15 kHz bandwidth. “We are now able to measure changes in an object’s position when it moves less than the diameter of one of the molecules in the object,” says Don Martin, Lion Precision president. The CPL490 can resolve target position changes of less then 100 picometers while objects are moving at 15 kHz. When bandwidth is increased to 50 kHz, a remarkably high frequency for capacitive sensors, the precision is still less than 0.3 nanometers.
An ever increasing selection of probes and ranges puts more flexibility and capability in the hands of engineers, designers, and researchers needing incredibly precise measurements of changes in position of a target, even when it is moving at a high rate of speed.
“The CPL490 has now opened a viewing window into the dynamic nano world enabling spindle manufacturers and designers to take the next step in precision,” according to Don Martin, Lion Precision president. Many industries including hard-disk drive, semiconductor and electron microscopy require measurement of position with increasing precision. “Some new technologies can’t take the next step until they are given the ability to quantify these tiny movements. We are now able to provide that,” adds Martin.
The CPL490 is a new capacitive sensor module in Lion Precision’s Elite Series product line. It has a typical resolution of 7 parts-per-million and a thermal stability of 0.02% of Full Scale /°C. The Elite Series is a modular system also offering signal processing and other capacitive sensor modules.
Probes for the CPL490 include internal electronics and are now available with a wider selection of measurement ranges. The probes feature an 8 mm diameter clamping area for probe mounting and are available in four different versions. The options enable users to select the best combination of range, bandwidth and resolution for their application.

In 1958, Lion Precision was the first company to provide capacitive displacement sensors to industry. The company has expanded its product offering to include eddy-current displacement sensors and some application specific sensors for the machine tool, packaging and PCB industries. The company is built on assisting users with sensor selection and implementation by providing technical knowledge resources, expert guidance and optimized systems including custom designs. Lion Precision provides high-performance noncontact sensors and experts to help use them.
