1 Electronic Length Measuring Equipment N-1

2 TESA LENGTH MEASURING EQUIPMENT WITH INDUCTIVE PROBES TESA offers a complete family of value sensors (electronic probes) as well as dedicated measuring instruments for the most demanding applications. Our standard probes also known as half-bridge probes operate according to the electrical principle. They do not require any special setting. Electronic probes that are used in conjunction with measuring instruments from other manufac - turers work partly on the basis of a differential transformer. These probes are known as LVDT (Linear Variable Differential Transformer) probes. TESA also offer a full range of this kind of probes which, however, need to be fitted with a convenient socket and further adapted, accordingly. For more details about TESA half-bridge or LVDT inductive probes, read the information that follows. Countless Measuring Capabilities All TESA electronic probes can either be used with hand-held tools, whether internal or external, or in conjunction with other typical measuring devices and supports. TESA can supply such executions as axial probes with linear displacement of the meas uring bolt, angled probes with inclinable lever or probes with parallel guiding that are specially designed for multigauging devices as well as any other equipment for in-process inspection thus allowing to spare many assembly components. With a very few exceptions, these probes perform comparative measurement, essentially. Based on a master standard, which can either be a gauge block, a setting ring or any other workpiece accepted as such, a number of sizes are compared on the test piece. All measurements are taken with high accuracy. The bias errors usually count for very little in the uncertainty budget since the comparison is made between two values nearly equal to the measurand. Random errors are also significantly reduced as display setting and all subsequent measurements are usually made under the same conditions. TESA provide measuring instruments equipped with an analogue and/or digital display, depending on their type. Internal Data Processing The measurement signals are processed differently according to the measuring application. Mathematical Data Processing Signal processing can equally be made with positive or negative polarity signs. The use of one single probe enables single measurement of internal or external dimensions while the combination of the signals of two probes produces either a «sum measurement» or a «difference measurement». Value Storage Provides the needed safety for your dynamic measurement cycles. The smallest or highest value as well as the difference between both values are some of the part features that are questioned when capturing form and position errors. Value Classification Uses limit deviations to classify the measured values while producing additional control signals usable through a remote unit. N-2 B-2

4 TESA Electronic Probes at the Fore front in Precision Measurement TESA is a leading designer, manufacturer and user of inductive probes for more than 4 years. Its high-precision electronic probes are made to withstand the stresses sustained in the production environment where they can be constantly used for series inspection. But, these probes are also designed for high accuracy measurements such as those performed in gauge block calibration, for instance. All electronic probes are mounted on ball-bearings, except for miniature axial probes. Ball-bearings are virtually insensitive to radial forces. Probe guide system is efficiently protected against the penetration of solid and liquid contaminants by sealing rubber bellows. In normal conditions of use, nitrile elastomer rubber bellows are sufficient. For applications where the probes remain permanently in contact with cooling and lubricating agents, we would recoend the use of rubber bellows. Sealing bellows ensure full airtightness so that the measuring bolt is retracted by throwing off the air contained in the probe. This provides optimum protection of the guiding system as no device is used. Electronic signal amplification produces excellent repeatability and low hysteresis. Resolution is as high as,1 µm Mounting stem or probe housing 2 Coil system 3 Element mounted between the ferromagnetic core and the measuring bolt for the correction of varying coefficients of thermal expansion 4 Force compression spring 5 Anti-rotation guiding system 6 Ball cage 7 Setting element for limiting the measuring bolt travel 8 Probe insert 9 In-between tube being part of the coil system 1 Ferro-magnetic core 11 Force spring stop 12 Ball-bearing guiding tube 13 Measuring bolt 14 Sealing rubber bellow 15 Mechanical device for zero-setting 8 Sensitivity of standard half-bridge probes used in conjunction with TESA and MERCER electronic probes All given values are valid for the following reference conditions: Drive voltage Drive frequency Adjustment load 3 V < 5 V 13 khz 5 khz 2 kω 1 kω 15 For any probe type mv/v/ mv/v/ 73,75 5 N-4 ø17 65 ø3,8 Dimensions of the connector fitted on all TESA probes.

5 Operating Principle All TESA electronic probes (value sensors) work based on the inductive principle with contact of the workpiece. They are fitted with a coil system inducing an alternating output voltage that depends on the the position of the ferro magnetic core. When syetrically positioned - i.e. at electrical zero - no voltage is impressed. A move of the core, which may be attached to the measuring bolt while the measurand is being taken, causes the inductance to change. This change generates a signal that is amplified and rectified before being displayed and further output. Depending on the instrument type, the analogue signal will be shown on a voltmetre or a numerical display after a digital transformation. Unambiguous assessment of the meas ur and (at bolt position) to the signal (dis played value) is the main characteristic of analogue value acquisition. One of its distinct advantages lies in the value primarily displayed, which will be reproduced in the event of a power cut (switch-off or power failure). -S Inductive measuring s Travel U Output current Electrical zero L Linearity range Lf Linearity error L The linearity range L, which is the range within which the max. perm. errors are contained, is equal to the measuring range. The max. perm. errors are limiting values given for the linearity errors. +U -U L L f +S TESA Standard Half-Bridge Probes For TESA Measuring Equipment These probes have two serial coils with middle output mounted side by side, which are energized by a sinusoidal alternation at 3 khz.

35 Configuration and Use of TESA FMS Probes The following examples provide you with a number of possibilities to activate and retract the measuring insert during your measurement cycles. Example A Moving the probe insert toward the part to be inspected using the measuring force produced through the compression spring. No insert s retraction. Effect The insert remains into position. Exchanging parts is made with contact of the probe under the measuring force Fixed probe body 2 Moving probe body 3 Measuring element with fine adjust 4 Adjustable stop 5 Spring set for the measuring force 6 Mounting bores 7 Holder for the probe insert Example B Moving the probe insert toward the part to be inspected using the measuring force produced through the compression spring. Insert s retraction by pneumatic pressure. Effect Exchanging parts is made with no contact of the probe Spring set for the measuring force 8 Pneumatic jack, No Connector (No , page N-45) Example C Activating the measuring insert towards the part to be inspected by using the measuring force produced by the compression spring. Insert s retraction by disabling the pneumatic pressure. Effect Exchanging parts is made with no contact of the probe, thus providing absolute security since the probe insert retract itself due to a lack of. This configuration is also applied where there is no room on the left side for the pneumatic jack (as shown in the example B) The force of the spring set (5) must be equivalent to the force of the auxiliary spring-loaded element (1). 5 Spring set for the measuring force 8 Pneumatic jack, No Connector (No , page N-45) 1 Auxiliary springloaded element, No N-35
