Product catalog summary
Overview: The document provides detailed technical specifications and installation guidelines for T14, T20, and T40 eddy current probes, which are used for contactless distance measurement in industrial environments. These probes are known for their precision, resistance to contamination, high temperatures, and pressure.
Technical Specifications:
  • Measurement Range: T14 (0-14 mm), T20 (0-20 mm), T40 (0-40 mm), with extended ranges up to 45 mm.
  • Linearity: ±0.15% of range.
  • Resolution: Varies with frequency, with the highest resolution at 10 Hz.
  • Temperature Range: Sensors operate between -40°C to 150°C, with cables rated from -55°C to 200°C.
  • Protection Class: IP68, ensuring durability in harsh conditions.
Cable Configuration: The sensors use a multipole female LEMO connector, with options for BNC or SMB connectors. It is recommended to minimize connections to reduce failure risks.
Basic Module TX: The TX-Driver supports single or dual-channel configurations, offering high dynamic performance with a sampling rate of 124 kSa/s. It includes USB and CAN-bus interfaces for data transfer.
Calibration: Probes are factory calibrated for specific materials, with options for custom calibration. Calibration certificates include sensitivity, target material, and linearity data.
Installation Guidelines:
  • Electrical Installation: Ensure dry, stable temperature locations for the TX-Driver, and use shielded cables to prevent interference.
  • Probe Installation: Install probes without stressing cables, and ensure the measurement field is appropriately sized for the target object.
Precautions: Avoid shortening cables, protect against environmental damage, and ensure proper alignment with the electronic system. The sensors should not be used in radioactive environments.
Order Code: Details the available configurations for sensors and connection cables, including standard and optional versions.

The sensors are supplied with a multipole female LEMO connector as standard. For connection to the TX-Driver a cable with BNC connector is required. Optionally the cable are equipped with a SMB connector. The SMB connection is performed as BNC/SMB adaptor. Please note: The connector housing has an outer diameter of 6.5 mm. This facilitates the installation in particular with narrow conditions. If the cable is durably affixed, it might be desirable only to remove the probe from the entire cable. It is recommended to avoid unnecessary connections within the cable as it increases the probability...

eddy current sensors T14/T20/T40-5

The processor based design admits linearities less than 0.1 % - which is an exceptional feature for this sensor technology. Remarkable performance allows highly dynamic measurements with 124 kSa/s. The TX-Driver is available as single- or dual-channel device. As standard, the device provides a USB and a CAN-bus Interface. The power supply is a galvanically isolated wide input from 10.5..36 (27) VDC. All available sensor heads can be connected with the basic module TX. ■ Probe and analogue output: Isolated output and high-speed signals via BNC connector. Selectable output signals 10 V, 5 V, ±...

ELECTRICAL INSTALLATION PROBE INSTALLATION OBJECT SIZE AND THE EDDY CURRENT MEASUREMENT FIELD Choose a dry location, preferably with a stable temperature for the electrical installation (TX-Driver) such as electrical cabinets, terminal boxes, housing, etc. Connect the supply line, probe lines and output lines. Please ensure that all supply and signal lines are laid separately from energy-carrying lines such as supply and discharge lines from converters and drives, lines from ovens and synchronised appliances or generator lines, etc., in order to avoid malfunctions in the signal behaviour.
