The TR-100 is designed to measure and control the temperature of the device using four PT100 sensors connected via two – or three-wire circuitry, followed by displaying the temperature on the display and issuing alarm signals when which or parameters exceed the set limits.

Can be used for protection:

• engines and generators
• three-phase dry transformers with additional control of core or ambient temperature

The TR-100 has universal power and can use any voltage from 24 to 255 V, regardless of polarity.

The TR-100 can use the following types as temperature sensors:

• PT-100 platinum sensor with a nominal resistance of 100 ohms, at 0 ° C
• PT-1000 platinum sensor with a nominal resistance of 1000 ohms, at 0 ° C
• KTY-83 silicon sensor with a nominal resistance of 1000 ohms, at 25 ° C
• KTY-84 silicon sensor with a nominal resistance of 1000 ohms, at 100 ° C
• PTС (1, 3, 6 serial switching on) cold resistance of the sensor 20-250 Ohm
