Temperature transmitter for Pt100 sensor input, DC 4-20mA output.
■ Converts the measurement input of a standard Pt100 sensor (100Ω/0℃) to a 2-wire linear 4-20mA current signal ■ Achieves high accuracy and stability through digital linearization technology ■ The scaling for the temperature range corresponding to 4-20mA can be freely set within the range of -200 to +650℃ (minimum span 25℃) (The factory default setting is 4-20mA = 0-100℃) ■ A red LED inside the transmitter warns of abnormal conditions during setup (temperature outside the set range, sensor disconnection or short circuit) ■ Equipped with reverse polarity protection circuit ▲ For Pt100 sensor input, measurement range -200 to +650℃, scalable ▲ Built-in Pt100 sensor (HD786TR1/TR2) ▲ All models have DC 4-20mA output ▲ Standalone, wall-mounted, and DIN rail-mounted types
