Transducers for the LWH / TLH series

These transducers are specifically designed to work with Novotechnik’s LWH/TLH linear potentiometers. They provide a stable reference, measure the wiper signal ratiometrically, and quickly and precisely scale the actual measurement range in use. The result is PLC-compatible standard signals with minimal configuration and calibration effort.

Precise adaptation to linear potentiometers

Our MUW series transducers are adapter modules for the TLH and LWH series linear potentiometers and are integrated into the connector. They provide a stable 10 V reference voltage, sense the wiper signal with high impedance and in a ratiometric manner, and scale the actual measurement range using trimmer potentiometers. This provides you with reproducible 0–10 V, 0–20 mA, or 4–20 mA signals for PLCs—without the need for complex PLC scaling. This reduces commissioning times and supports short cycle times.

Practical examples and areas of application

The following practical example illustrates this: In a clamping device, only a partial stroke of a linear encoder is used. The zero point and measuring range can be adjusted over a wide range using trimmer potentiometers, ensuring that the output precisely covers the desired range. Applications: Mechanical and plant engineering, handling/robotics, machine tools, test and measurement stands.

Your benefits

• Signal conditioning integrated into a connector housing for LWH/TLH linear potentiometers
• Setting the zero point and range
• Standard signals: 0–10 V, 0–20 mA, and 4–20 mA; directly compatible with PLCs
• Excellent linearity, low temperature drift

FAQ

• Are other potentiometers compatible as well?
  No, because it is designed to fit the hydraulic connector, the MUW only works with LWH and TLH.
• Is teach-in required?
  No, but it improves the output resolution if the maximum travel range of the position sensor is not fully utilized.
