ERTL — linear potentiometer with analog output signal 4-20 mA OPKON

OPKON ERTL Linear Potentiometer

ERTL — Precise Linear Position Control with 4–20 mA Analog Output

The ERTL Series of linear potentiometers by OPKON are reliable transducers that convert the position of a rod (actuator) into a stable analog signal. They are used for the absolute measurement of an object's position within a specified measurement range.

The operating principle relies on voltage division across a hybrid conductive film, ensuring high accuracy and excellent repeatability of measurements.

Key Advantages and Features ✨

• Absolute Precision: Highly stable output signal with excellent repeatability.

• Temperature Stability: Extremely low temperature drift guarantees reliability even with fluctuating ambient temperatures.

• Durability: Mechanical service life is rated up to 100,000,000 cycles.

• Versatile Outputs: Wide range of analog signals, including direct and inverted outputs:

  • Current: 4-20 mA (standard) or inverted 20-4 mA.

  • Voltage: 0-20 V, 0-10 V, 20-0 V, 10-0 V.

• Robust Housing: Anodized aluminum housing and stainless steel rod provide an IP65 protection class.
