The Simscape > Foundation Library > Thermal Liquid > Sensors library should have a "Pressure & Temperature Sensor (TL)" block.
(whew, that's a lot of words)
Anyway, you should be able to connect these sensor blocks to the A and B ports of the pipes to get the temperatures you need. If you want the absolute temperatures, you want to put the "A" port of the sensor to the pipe location and the "B" port to an "Absolute Reference (TL)" block.
