SICK has launched the UP56 Pure ultrasonic level sensor with polypropylene housing to provide accurate and continuous non-contact level sensing in vessels that contain aggressive fluids such as those used in electronics and photovoltaic manufacturing.
“The UP56 Pure uses a time-of-flight ultrasonic pulse for continuous level measurement from top to bottom of the vessel, achieving greater control than the conventional point level capacitance sensors typically used to detect top, middle and bottom points,” explained Darren Pratt, product manager for Sick UK’s industrial instrumentation division. “The new SICK UP56 Pure range is mounted inside the chemical tank in an immersion tube. There is no need for an external by-pass tube on tanks, saving cost and eliminating the possibility of accidental escapes or leaks. A mini version is also available with a very short body enabling installation in confined spaces. As well as enabling sophisticated alarm monitoring, when tank levels are nearing critical filling levels, continuous level measurement can provide an indication of process line performance, such as pump and filling efficiency and mix dosing.”
The SICK UP56 Pure and Pure Mini variants are contained within an IP67 housing and have all wetted parts coated with PTFE or manufactured from polypropylene to deliver long life and reliability in challenging corrosive environments.
The SICK UP56 is available in three measuring ranges, 30 – 500mm, 85-1500mm and 65 – 1500mm when used in with an immersion tube, providing application versatility for different sizes of tank and process requirements.
The SICK UP56 mounting incorporates a high security GF (George Fischer) mount. The UP56 features excellent pressure resistance (0-6 bar Pure and 0-2 bar Pure Mini) enabling use in pressurised systems. The sensor will withstand process temperatures up to 80oC.
The SICK UP56 offers pre-calibrated plug-and-play level sensing but can also be re-configured using the same PC-programming tool used with other SICK ultrasonic sensors.
