What would be the best way to hook up a LM335 sensor to the analog inputs of the T100MD? Also what formula would i have to use?

Since the LM335 has output of 10mV/K, you can wire up the sensor such that its output voltage fall within the range of the PLC's analog inputs (0-5V for most PLC or 0-1V for 2 of T100MD1616+) and then you will be able to measure the voltage. The reading obtain is 0-4092 which can be scaled to units you want.
For other interface circuits for LM335, check with NS data sheet:
