AI Overview
Galvanically isolated 4-20mA temperature transmitters convert RTD or thermocouple signals into a linearized, interference-free current loop signal, with models typically offering 3-way isolation (input/output/power) to eliminate ground loops. These devices commonly come in head-mounted (DIN Form B) or DIN rail-mounted formats and support user configuration for sensor type and temperature range, featuring low temperature drift for high accuracy.
Top Galvanically Isolated Temperature Transmitters
- KROHNE OPTITEMP TT 33 C: A universal, 2-wire head-mounted transmitter with galvanically isolated input and output. It offers high precision (±0.08% of span) and rapid response time (0.15s), suitable for RTDs and thermocouples.
- Datexel DAT1066: A PC-programmable, head-mounted transmitter that supports TC, RTD, mV, and Ohm inputs with galvanic isolation for enhanced reliability.
- Knick P44000 Series: These transmitters offer high-voltage insulation (up to 6.6 kV AC/DC) for Pt100 inputs, designed for high-voltage applications.
- TXISORAIL-HRT V7: A DIN rail-mounted isolated transmitter commonly used for industrial process control.
