For these reasons, it is recommended the probe tips not be touched. Helpful Technical Support Documents Online Lion Precision’s web site has a large selection of technical documents (TechNotes and Application Notes) in the Technical Library. These documents provide detailed descriptions of the operation and use of Lion Precision high-performance sensors.
CPL190/290 Sub-Nanometer Capacitive Displacement Sensor The CPL190/290 Capacitive Sensor is a precision, noncontact measurement device. The CPL190 output voltage changes in direct linear proportion to changes in the gap between the probe ZERO and the target. The sensor is normally used to measure conductive targets, but it can also be used with nonconductive targets under the right conditions.
DO NOT PULL ON THE CABLE. Multiple Channel Measurements Using multiple sensors on the same target requires that the sensor excitation voltages be synchronized. This is done automatically by the Elite Series enclosures. In addition, even and odd channel numbers use inverted (180°) excitation...
voltages. This eliminates offset and scale errors that may otherwise occur with poorly grounded targets such as semiconductors. For details on use with ungrounded targets and the advantage of inverted excitation voltages, refer to Lion Precision TechNote LT03-0022 Capacitive Sensors and Ungrounded Targets, available at www.lionprecision.com; click on Technical Library.
CPL490 Wide Bandwidth Picometer Capacitive Displacement Sensor The CPL490 Capacitive Sensor is a very high precision, noncontact measurement device. The output voltage changes in linear proportion to changes in the gap between the probe and the target. The sensor is normally used to measure conductive targets, but it can also be used with nonconductive targets in some applications.
Overview of Front Panel Controls, Indicators, and Connectors Zero Adjust Provides a DC shift of the analog output voltage after the probe is initially positioned. The adjustment has a range of ±1 VDC. Typically, the analog output voltage is adjusted to zero volts at range center.
Changing CPL190/290/490 Bandwidth Settings CPL190/290 The CPL190/290/490 provides a two-position DIP switch for setting bandwidth. When changing bandwidth, change all modules in the system. Bandwidth Switch Bandwidth is a system-wide setting; bandwidth switches on the modules within a system are interconnected. All of the bandwidth switches must be in the same position for predictable results.
MM190 Meter and Function Module The MM190 Module displays dimensional values derived from sensors within an Elite Series MM1 90 system. Any two channels can be summed and peak capture functions can be performed on an individual channel or a resulting sum. The displayed value is also provided as an analog voltage via a front panel BNC connector.
Peaks Five options are available: NONE – Display is real-time value of input channels. MAX – Displays the most positive value since the Reset (RST) button was pressed. MIN – Displays the most negative value since the Reset (RST) button was pressed. TIR –...
The TMP190 Module monitors up to seven channels of temperature data and provides signal conditioning and input connections for encoder and index inputs. Requirements The TMP190 is used with the Lion Precision Spindle Error Analyzer (SEA) and requires the SEA software to access the temperature signals. Operation – Temperature Sensing...
Making Temperature Measurements Place temperature probes in positions to take desired measurements. When measuring surface temperatures, solid mechanical contact is important. Use Spindle Error Analyzer (SEA) Software to extract temperature readings. Block Diagram - Temperature Connections to Temperature Probes The two wires of each temperature probe are connected according to the chart below. The probes are by nature unpolarized so there is no differentiation between the two conductors.
Encoder/Index Pulse Input The TMP190 also processes encoder and index pulse inputs for use by the Spindle Error Analyzer. The module performs basic signal processing on the incoming signal then passes the conditioned signal to the data acquisition hardware for analysis by the software.

Accessories Air-Bearing C-LVDT: Capacitive LVDT-Type Contact Sensor The Air-Bearing C-LVDT converts a capacitive sensor using a standard capacitive probe into a high-precision contact displacement sensor similar to an LVDT. The capacitive probe is installed in the top of the C-LVDT body where it measures the location of a target connected on the inside end of the stylus.
