TESA ELECTRONIC LENGTH MEASURING EQUIPMENT Technology TESA INDUCTIVE PROBES AND ELECTRONIC EQUIPMENT TESA probes At the cutting edge of technology TESA develops manufactures and remains a leader in the inductive probe sector with an experience of more than 40 years. It offers a complete and unique line of probes designed to meet the requirements of varied as well as demanding applications. Dimensional inspection of medium and large batches of parts in multigauging fixtures represents a major application area where measuring speed coupled with a high level of accuracy is needed. High precision inductive probes (type GTL-21 HP) are for example also suited for the MEASUREMENT of gauge blocks. The display resolution can reach a digital step of 001 ym On request TESA probes can be supplied in versions compatible with the electronic equipment of other suppliers. Typical qualities of TESA inductive probes excellent repeatability durability and longevity All TESA inductive axial movement are mounted on a ball bearing with the exception of miniature models. The ball bearing guidance system is insensitive to any radial force exerted on the probe housing. An anti-rotation guiding system ensures perfect movement of the mechanical guide. The axial probe guide system is effectively protected against penetration of liquids (oils) or solids (dust) by sealing bellows of high elastic quality. Under normal conditions the standard nitrile elastomer bellows provide sufficient protection against oils and solvents. For applications where the probes remain in prolonged contact with coolants or lubricants and aggressive chemicals Viton bellows are recommended. Viton is a fluoreleastomer resistant to the heat of oils and aggressive chemicals. The retraction (lifting) of the measuring bolt rod can be made by the suction of air (vacuum) accumulated within the probe thanks to the airtightness provided by the sealing bellows. This method of working principle does not use any mechanical device ensures the operation of the guidance system in an optimal manner. Similarly the probe can be moved into its measuring position by a pneumatic activation (pressure) depending on the probe model. Inserts (measuring inserts) can be replaced or exchanged. A wide choice of geometrical forms and sizes are available The measuring force can be adjusted by changing the spring depending on the probe model. The probes integrate an electronic amplifier of the signal without relying on any mechanical conversion device. Thus these probes are distinguished by their high repeatability and very low hysteresis errors. GT-31 Probe FMS TT20 USB probe Wireless probe TESA
