ATM
Averaging Temperature Sensor

GENERAL
ATM is an average temperature sensor which is installed from tank top.
ATM consists of plural temperature elements which have different lengthwith fixed interval. In one element, several Pt sensors are distributed inequal interval and these Pt sensors totally form Pt 100 ohm. Thus, oneelement detects vertical average temperature.
ATM is connected to Tokyokeiso’s Intelligent type servo operated tankgauges or digital tank data transmitters by which the longest temperature element below the liquid surface is selected.
