Model OTMT84: PROFIBUS ® PA profile 3.02 Model OTMT85: FOUNDATION™ Fieldbus H1 Explosion-protected version Ex ia (intrinsically safe/FISCO) and Ex ec available
The models OTMT84 and OTMT85 temperature transmitters with FOUNDATION™ Fieldbus or PROFIBUS ® PA communication feature a universal input for temperature measurements with resistance thermometers, thermocouples, resistance sensors and voltage sources, which are possible with or without customer-specific linearisation. Differential, average or redundancy temperature measurements can be realised. The temperature transmitters are characterised by their reliability, long-term stability, high accuracy and extended diagnostic options. For FOUNDATION™ Fieldbus, the OTMT85 is available with LAS functionality (Link Active Scheduler) and PID controller. These functionalities allow for master-independent regulations in the field instrument. The models OTMT84, OTMT85 temperature transmitters have a polarity-independent bus connection. Due to their small dimensions, the temperature transmitters are suitable for mounting into form B connection heads in accordance with DIN EN 50446. The temperature transmitters are delivered with a factory configuration or configured according to customer specifications within the given limits.
