Detecting liquid in pipes

02 March 2020

The SICK T-Easic FTS is a new thermal flow switch designed to detect liquid flow in pipes – for example in pumps, machine tool lubrication, or industrial cleaning systems.

Combining both flow and temperature measurement in one IO-Link enabled sensor, the SICK T-Easic is available in a choice of IP67 industrial or IP69 hygienic stainless-steel versions. It can be set up to work with most medias and is said to be suitable for use with process temperatures between -40°C and 150°C and pressures up to 100 bar.

It could, for example, be put to work monitoring coolants and lubricants in machine tools, for oil management in hydraulic systems, or for run protection of pumps. It is also suited to use in Clean-in-Place and Sterilise-in-Place systems in food processing, bottling and pharmaceutical industries. With probe lengths of 60mm, 100mm and 200mm, the flow switch can be inserted in pipes with diameters from 25mm up to 400mm. 

The sensor features two digital outputs. It can monitor measured flow and temperature values and send a signal to the higher-level machine control when either the high or low switch points are exceeded. On the industrial version the switch points can be adjusted via the onboard display. The measured flow rate and temperature values, as well as diagnostic data are available via the IO-Link interface. The sensors can be set up with a PC or HMI, via IO-Link or using SICK’s SOPAS engineering tool.
