WA-T: Precise Inductive Displacement Measurements up to 100 mm

The proven WA-T probe-style displacement transducers are based on the differential inductive bridge principle and utilize a quarter-bridge circuit. The bridge is completed within the sensor to form a full bridge circuit, enabling straightforward connection to a bridge amplifier. For even simpler integration, the WA-T is also available with an integrated inline amplifier.

Built for demanding industrial environments, WA-T sensors are hermitically sealed to protect against dirt, humidity  and contamination. The displacement transducers combine rugged mechanics with excellent temperature stability, ensuring reliable performance under challenging conditions. The spring-loaded probe pin automatically maintains contact with the measurement object, reducing installation effort. Based on the proven inductive bridge principle, WA-T sensors deliver exceptional long term stability.

New: Inline amplifier options available. Choose from:

  • 4 – 20 mA current output
  • 0 – 10 V voltage output
  • IO-Link digital interface

Configure your WA-T+ Sensor here.

Key features:

  • HBK accuracy class: 0.2
  • Accuracy class 0.1 with inline amplifier versions
  • Measurement ranges: From 2 mm – 100 mm
  • Output signals: mV/V (passive), 0 – 10 V, 4 – 20 mA or IO-Link

 

Industry-standard interfaces for easy integration

Choose the interface that best suits your application. In addition to passive mV/V output, WA-T sensors can be supplied with voltage, current, or IO-Link outputs for simplified installation and improved measurement performance.

Benefits:

  • Minimized linearity error of 0.1%, if an inline amplifier option is chosen.
  • Digital version with IO Link interface includes peak detection, Bessel and Butterworth filters, limit switches and a digital output
  • Delivered as a calibrated measurement chain, just connect and start the measurement
  • With IO-Link: Immediate measurement values in millimeters when connected to an IO-Link master
  • Versions with IO-Link Interface: Lower installation and operating costs through faster mounting, no parameterization required, and reduced cabling costs.

Benefit from higher accuracy, easier installation, and lower system costs with the WA-T+ inline amplifier options.

Extensive configuration options

Available options:

  • Multiple cable lengths and connector versions
  • Straight or 90° cable / connector outlets
  • Plug mounting options, connectors, and TEDS available on request
  • Low temperature versions down to –25°C
  •  High temperature versions up to +150°C
  • More than 15,000 configuration combinations.

The result is a displacement transducer that can be precisely matched to your application requirements.
