Ultrasonic level sensor VS61

The ultrasonic level sensor VS61 is a sensor for continuous level measurement of liquids or bulk solids. With a measuring range of up to 5 metres for liquids and up to 2 metres for bulk solids, it offers an output signal of 4-20 mA and a measuring accuracy of ±4 mm. The sensor is chemical resistant, thanks to PVDF material with EPDM seals, and offers optional explosion protection and PLICSCOM.

Our sensor works by emitting ultrasonic waves that are reflected from the surface of the medium to be measured and sent back to the sensor. The time taken for these waves to travel back and forth is measured and used to calculate the distance to the medium. This enables non-contact measurement of the fill level, regardless of the properties of the medium, which makes the sensor very versatile.

Features Ultrasonic level sensor VS61

  • Measuring range: in liquids up to 5 m / in bulk solids up to 2 m
  • Measuring deviation: ±4 mm or <0.2 %
  • Output signal: 4...20 mA/HART - two-wire
  • Process pressure: -0.2...+2 bar
  • Process connections: G1½ or 1½ NPT

Your benefit

  • Price-favourable solution for simple applications
  • Maintenance-free operation through non-contact measuring principle
  • Reliable measurement independent of product features

Area of application 

The VEGASON 61 is an ultrasonic sensor for continuous level measurement of liquids or bulk solids. Typical applications are the measurement of liquids in storage tanks or open basins. The sensor is also suitable for the detection of bulk solids in small vessels or open containers. The non-contact measuring principle is independent of product features and allows a setup without medium.
For this instrument, new radar sensors with connection housing VEGAPULS 11, 21 or 31, or radar sensors with fixed connected cable VEGAPULS C 11, C 21, C 22 or C 23 are available as alternative.
