New flexible temp. Tx gives user flexibility

Status Instruments has launched a new ‘smart’ temperature transmitter range that accepts resistance signals including RTD, Slidewire  or Thermocouple  sensors, and converts them to a standard industrial (4 to 20) mA transmission over a user programmed range.

With its flexible design, the TTR200 will accept more than 30 resistance sensors, including Pt100, Pt500, Pt1000, Ni types, Cu types and slidewire sensors up to 100K and resistance up to 10 Kohms. The TTC200 accepts 13 different thermocouples. In addition, Status has also provided the facility to download additional sensor characteristics as well as the user’s own 22 point linearisation table via the free programming software.

Zero offset adjustment and zero / span alignment to process is available to help minimise system errors. Input signal damping is also available to help slow the output (if required) for a very rapid rate of change of input signal.

PC configuration, which is performed quickly using Status’ USB port-driven configurator, allows the user to select sensor type, range, filter, Tag number, units and error signal without the need for calibration equipment.

Configuration set up may be saved as a PC file for later use. In addition the user may read live process data when connected to the PC allowing for sensor off-set calibration, where the user can offset the value to correct for any sensor offset.

If required the desired range can also be specified at the time of order, removing the need for user configuration.
