Dwyer BTT-D04-2 Temperature Transmitter ensures accurate temperature measurements from 32 to 122 °F (0 to 50 °C), with a precision of ±0.5 °C @ 25 °C. It operates on 13 to 36 VDC power supply for current models and 13 to 36 VDC or 16 to 28 VAC for voltage models. With a response time of 100 ms, it offers an output signal of 4 to 20 mA or 0 to 10 VDC, depending on the model. The transmitter features an IP20-rated enclosure, screw terminal block electrical connections, and a Pt 1000 O RTD DIN Class A 0.00385 Ω/°C temperature sensor, minimizing thermal effect to ±0.01%/°C.
