    Abstract: An industrial process temperature transmitter (100) for measuring a temperature of a process medium (102) includes a temperature sensing unit (104), a compensation circuit (120), and an output circuit (126). The temperature sensing unit includes a process temperature sensor (105A) that is separated from the process medium by an isolation wall (108). The temperature sensing unit (104) is configured to produce a temperature signal (122) that is indicative of the temperature of the process medium (108) based on a process temperature signal output (106A) from the process temperature sensor (105 A) during a temperature measurement. The compensation circuit (120) is configured to compensate the temperature signal (106A) for a response time of the temperature measurement to a change in the temperature of the process medium (102), and output a compensated temperature signal (122). The output circuit (126) is configured to produce a temperature output (128) as a function of the compensated temperature signal (122) corresponding to the temperature of the process medium (108).
