Temperature Transmitters
TWO WIRE SMART TEMPERATURE TRANSMITTER
TT 04H
TT-04H Smart Temperature Transmitter is a high-performance industrial transmitter designed for precise temperature measurement and signal conversion. It accepts inputs from RTD (PT-100 / PT-200), all standard thermocouples (B, E, J, K, R, S, T), resistance, and millivolt signals, offering wide application flexibility. The transmitter provides a 4–20 mA output with HART communication and features a backlit LCD display for online temperature indication and local operation. With ±0.1% full-scale accuracy, fast response time (<300 ms), and software calibration, it ensures reliable and stable performance. The unit supports single or dual sensor inputs, sensor redundancy, and advanced functions such as ΔT and peak value measurement. Housed in a die-cast aluminium or SS-316 enclosure with IP-67 protection and ATEX (Ex d) certification, the TT-04H is suitable for harsh and hazardous industrial environments.
Configure the transmitter and electronics based on application, environment, and compliance requirements.
