Endress + Hauser  has released an in-head Foundation Fieldbus based temperature controller and transmitter with two input channels.

The new iTemp TMT85 offers universal temperature input capabilities including RTDs, thermocouples or voltage and is suitable for use with 2-wire, 3-wire and 4-wire sensor technology.

The iTemp TMT85 automatically detects the type of sensors connected for self configuration.

For maximum versatility, the iTemp TMT85 also offers sensor diagnostics with the ability to monitor open circuit, cable corrosion, wiring errors and device hardware errors.

With galvanic isolation between the Foundation Fieldbus and sensor inputs and for hazardous area use, the transmitter offers accurate and reliable temperature measurements in a wide variety of applications.

The ability to connect two temperature sensors to the iTemp TMT85 provides redundancy of measurement and guarantees measurement availability, should either sensor fail.

Another advantage of the dual sensor capability is the ability to compare various performance parameters and provide diagnostics in case of sensor drift.

Termination of cables is available in traditional screwed format or new sprung terminals for quick and easy connection and release.

Whilst in-head transmitters are already recognised for cost savings when using thermocouples due to the elimination of expensive compensation cables, the iTemp TMT85 also embraces the Foundation Fieldbus philosophy wherein control resides in the field.

The compact DIN B style transmitter thus fits full PID control into small connection heads and remote housings.

“Together with Foundation Fieldbus technology, its reliability, long-term stability, high accuracy and advanced diagnostics make the iTemp TMT85 the ideal solution for critical processes,” says John Immelman, managing director, Endress+Hauser Australia.

Its dual channel functionality fits applications needing high level of safety, availability and risk reduction.
