Dwyer BTT-I06-2 is a Temperature Transmitter with a temperature range of 32 to 122 °F (0 to 50 °C) and an accuracy of ±0.5 °C at 25 °C. It operates on a power requirement of 13 to 36 VDC for current models, or 13 to 36 VDC or 16 to 28 VAC for voltage models. With a fast response time of 100 ms, it provides a 4 to 20 mA or 0 to 10 VDC output signal, depending on the model. The transmitter is enclosed in an IP20-rated casing and uses a Pt 1000 O RTD DIN Class A 0.00385 Ω/°C temperature sensor.
