Yamatake ATT60 and ATT70 advanced temperature transmitters

Click2Contact

The Yamatake advanced temperature transmitters, models ATT60 and ATT70, are field instruments that convert inputs from thermocouples, mVs and resistance thermo-bulbs into analog (4-20 mA) and digital signals and transmit them to receivers. Various parameters can be remotely set, and self-diagnosis can be performed through the Smart Field Communicator (SFC). They can also execute two-way communications between the SFC, or HART 375 communicator, and, via DE protocol, with the TDCS3000 or 3000X and a database, thus facilitating self-diagnosis, range resetting and automatic zero adjustment. Settings, adjustments and self-diagnosis can be done easily by SFC or HART communicator.

The following models are available: the Advanced Temperature Transmitter with FOUNDATION Fieldbus Model ATT60; the Smart Temperature Transmitters (Integral Sensor Type) Model ATT61/71; Temperature Sensor Model ATT90; and Metallic Protecting Well for Temperature Sensor Model ATT9X.

ThermoPLUS handles all thermal sensors, and any temperature range can be set as required within the one transmitter, thus giving the optimum range for a given process. The transmitters are available with a range of flexible sensor types, thus reducing engineering work costs.

The two-wire system of the models ATT60/70 requires no compensation wires or field cables, and the system has a self-diagnostics function. They can also work with abnormal ambient temperatures of -40 to 85°C.
