What does T1-T3 stand for in instrumentation terminology?

Temperature 1-3

Tank 1-3

Terminals 1-3

The labels T1 through T3 are about connection points on equipment. In instrumentation, the letter T is used to mark terminals on a terminal block or connection panel, and the numbers simply distinguish the different terminal positions. So T1, T2, and T3 refer to Terminals 1, 2, and 3 where wires or sensors are connected.

This is why the correct interpretation is that T1-T3 stand for Terminals 1-3. It’s not about temperatures, tanks, or test points in this context—the labeling helps technicians identify where to attach signals, power, or sensor inputs on the device.
