Does Rosemount have any models that can connect to two thermocouples/thermistors, with outputs for the temperature changes of both as well?

Other brands work too. Both input and output are two.
Rosemount models are available that can connect to two thermocouples/thermistors, with an output representing the temperature change for both of them. Go to this website and take a look: http://wenku.baidu.com/view/3c0c9bceda38376baf1fae6b.html
Honeywell also has integrated temperature control with similar functions
Rosemount has dual thermocouples/thermoresistors, but the output is a single signal; the dual setup is used for thermal redundancy. If one fails, another can be activated automatically, reducing maintenance time. The transmitter needs to be paired with 3144P. There is also a module that can connect 8 units, and the protocol is FF
We encountered a dual-element thermocouple temperature transmitter with two on one side. Use a stainless-steel explosion-proof junction box, with two temperature-sensitive modules inside.
