Status Instruments TTR200

TTR200 / TTR200X Temperature Transmitter for Pt100 Sensors, with calibration and linearisation features.

The TTR200 is our mid range transmitter for RTD or Slidewire sensors. It can accept many different types of RTD sensor such as Pt100, 500, 1000 etc and slidewire sensors up to 100K Ohm.
This product has a calibration feature where the output can be matched to the sensor on the input. It can be matched at zero, or both zero and span ends of the temperature range being measured. This is typically used when the product is being supplied with a calibration certificate matched to a particular temperature probe.
It is also possible to measure linear resistance up to 10K Ohms and slidewire sensors up to 100K Ohms.  The software allows a user linearisation function to be downloaded into the product. This allows the user to adapt the output to suit a non linear tank for example.
The TTR200X offers an excellent value ATEX approved version of the same transmitter for use in hazardous areas.
However, if you already know the specification you require, we can  configure the product for you at no extra cost.
