Sick UP56 Pure Ultrasonic Level Sensor

Sick UP56 Pure Ultrasonic Level Sensor

The non-contact ultrasonic level sensors from the Sick UP56 Pure range are specialised for wet chemical processes in the electronic and solar industry. The UP56 Pure level sensors have a PTFE protected transducer which is very hardwearing and durable, designed to be used in highly concentrated acids and alkalines.

The Sick UP56 Pure level sensor is easy to integrate thanks to the industry specific GF process connection. A high level of accuracy can also be acheived with fluctuating liquid densities, thus facilitating the use of dosing applications. 

In systems where the installation space is extremely limited, the UP56 Pure Mini is available. Use in containers with a lot of built in components is easily resolved by means of an immersion pipe.

Sick UP56 Pure Ultrasonic Level Sensor - Features & Benefits

  • Ultrasonic level sensor with very high chemical resistance
  • Non-contact measurement in immersion pipe of up to 1,500mm
  • PTFE-coated membrane and GF D40 process connection made of PTFE
  • Pressure resistant up to 6 bar, temperature resistant up to 85ºC
  • Different sizes available
  • Analog output selectable between 4mA to 20mA and 0V to 10V
  • Switching output for monitoring the maximum and minimum limit
  • Non-contact and non-wearing measurement reduces maintenance and service cost
  • Sensor replacement possible even with chemicals present, thus saving time and increasing availability
  • University applicable with acidic and alkaline processes
  • Flexible measurement system for different container sizes provides cost reductions
  • High-precision measurements, even in liquids with density fluctuations
  • Faultless operation with very limited installation space in the container
  • Switching and analog output in one sensor reduces amount of wiring, I/O and stocking costs
  • Simple and time saving configuration with Connect+
