TR-100 is used to measure and control device temperature via four RTD sensors connected in a two or three-wire circuit, with subsequent indication of the temperature on the display and alarm signaling in case of any parameters being outside the set range.
It can be used to protect:
- Engines and generators
- Three phase dry transformers with additional core or ambient temperature control
TR-100 can use any voltage between 24 and 225V AC, regardless of the polarity.
The following thermal sensors can be used by TR-100:
- PT100 – platinum sensor with nominal resistance of 100 Ohm at 0
- PT1000 – platinum sensor with nominal resistance of 1000 Ohm at 0
- KTY83 – silicon sensor with nominal resistance of 1000 Ohm at 25
- KTY84 – silicon sensor with nominal resistance of 1000 Ohm at 100
- PTC (1, 3, 6 serial connection), cold resistance of 20-250 Ohm
Temperature Range: -40 to +240 deg C
