HART® field Temperature Transmitter WIKA

HART® field Temperature Transmitter WIKA

The TIF series field temperature transmitters, consisting of a rugged field case, model T32 temperature transmitter and a model DIH display, have been designed for general use in process engineering.

They offer high accuracy, galvanic isolation and excellent protection against electromagnetic influences (EMI). Via the HART® protocol, the TIFxx is configurable (interoperable) with a variety of open configuration tools.

In addition to the different sensor types, e.g. sensors in accordance with DIN EN 60751, JIS C1606, DIN 43760, IEC 60584 or DIN 43710, customer-specific sensor characteristics can also be defined, through the input of value pairs (user-defined linearisation).

Through the configuration of a sensor with redundancy (dual sensor), on a sensor failure, it will automatically change over to the working sensor. Furthermore, there is the possibility to activate sensor drift detection. With this, an error signalling occurs when the magnitude of the temperature difference between sensor 1 and sensor 2 exceeds a user-selectable value.

The field temperature transmitter also has additional sophisticated supervisory functionality such as monitoring of the sensor lead resistance and sensor-break detection in accordance with NAMUR NE89 as well as monitoring of the measuring range.

Moreover, these transmitters have comprehensive cyclic self-monitoring functionality. Via the display, it is possible to show range alarms as well as MIN and MAX values.

The field temperature transmitter is available in various field case variants. Plastic, stainless steel and aluminium can be specified. It can be mounted directly on a wall. A pipe mounting kit is also available for fitting to pipes with a diameter of 1 … 2″. The field temperature transmitters are delivered with a basic configuration or configured according to customer specifications.
