Abstract: An industrial process temperature transmitter for measuring a temperature of a process medium includes a temperature sensing unit, a compensation circuit, an output circuit and a housing. The temperature sensing unit includes a process temperature sensor and a secondary temperature sensor. A temperature signal that is indicative of the temperature of the process medium is produced based on a process temperature signal output from the process temperature sensor and a secondary temperature signal output from the secondary temperature sensor. The compensation circuit compensates the temperature signal for a response time of the temperature measurement to a change in the temperature of the process medium, and outputs a compensated temperature signal. The output circuit produces a temperature output as a function of the compensated temperature signal. The housing is attached to an exterior of the process vessel and contains the secondary temperature sensor.

Abstract: An industrial process temperature transmitter for measuring a temperature of a process medium includes a temperature sensing unit, a compensation circuit, and an output circuit. The temperature sensing unit includes a process temperature sensor that is separated from the process medium by an isolation wall. The temperature sensing unit is configured to produce a temperature signal that is indicative of the temperature of the process medium based on a process temperature signal output from the process temperature sensor during a temperature measurement. The compensation circuit is configured to compensate the temperature signal for a response time of the temperature measurement to a change in the temperature of the process medium, and output a compensated temperature signal. The output circuit is configured to produce a temperature output as a function of the compensated temperature signal corresponding to the temperature of the process medium.
