Problem: How can I monitor the temperature difference between the hot product flowing in and the cooled product flowing out of a heat exchanger (∆T)?
Solution: Install RTD sensors at the inlet and outlet of the exchanger and connect them to our RIY configurable temperature transmitter. The RIY can be configured to provide a 4-20mA output proportional to the temperature difference to your DCS, recorder or other device. The difference is also displayed locally.
