TTx300-N - NINVA
HART Field Device
Non-invasive temperature measurement provides a simpler and safer way of measuring your process temperature without the need to shutdown, engineer and install a thermowell.
ABB offers two successful devices for temperature measurement:
• TSP341-N, a specially designed 2x3-wire RTD sensor for non-invasive temperature measurement.
This non-invasive temperature sensor includes a transmitter based on TTH300.
• TTF300-N, a field-mount temperature transmitter with defined classified hazardous area approvals.
This non-invasive temperature tranmitter is remotely connected to a TSP341-N without transmitter.
The ‘N’ in stands for non-invasive temperature measurement, with the integrated calculation algorithms developed by ABB. This takes ambient conditions, among other factors, into account during the measurement and therefore increase the accuracy of the surface measurement significantly. Accuracy and response time are in the range of temperature measurements with thermowell.

FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
