3PRODUCT DESCRIPTION
3.3 Product features and functions
3.3.1 Principle of operation
The T-Easic®FTS (Flow Thermal Switch)monitorstheowrateofliquids(e.g.,water,
aqueous media, oil, etc.).
This measurement method is based on the calorimetric principle. The sensor measures
thecoolingeffectoftheliquidowingpasttheheatedmeasurementprobe.Thehigher
theowrateoftheliquid,thegreaterthecoolingeffectontheheatedprobe.
Thesensorhastwocongurableswitchingoutputs(Q1andQ2)forowandtempera-
ture. Q1 can also be used for empty pipe detection. The sensor can detect whether
there is medium at the sensor tip and thereby detect an empty pipe.
The Q1 switching output also has an IO-Link interface (see “7.2.4IO-Link”).
Q2 can also be used as a pulse output or digital input.
Depending on the electrical version (“3.1.2Typecode”), Q2 can also be used as an
analog output.
Fields of application
The T-Easic®is particularly suitable for measurement tasks relating to coolant circuits,
pumps, heat exchangers, leak monitoring for process lines, dry-running protection
for pumps, as well as monitoring the oil in hydraulic systems, the lubrication of wind
turbines, and hydraulic circuits. Due to its high temperature resistance, the T-Easic®
isalsosuitableforuseinSIP(SterilizationinPlace)processes.

The cutting ring of the process connection adapter 1mustbe≥25mmawayfromthe
probe tip 2to avoid damage to the sensor element.
The sensor probe should be positioned in the middle of the pipe and must not be in
contact with the pipe wall.
Aminimumdistanceof≥10mmfromthetipoftheprobetothepipewallmustbe
maintained 4.
For medium temperatures above 100 °C, the distance between the bottom of the
housing and the top of the process connection adapter must be at least 25 mm 5.
NOTE:
If a Sick process connection adapter is used (see “14Accessories”), the 60 mm probe
cannot be used at process temperatures above 100 °C as the distances cannot be
maintained.
