APD 4001 RTD Differential Temperature Transmitters
RTD to DC Isolated Transmitter
The APD 4001 accepts an RTD temperature input and provides an optically isolated and linearized DC voltage or current output. The sensor type, temperature range and output range are factory set and can be specified as required. This provides an economical solution when a temperature sensor signal must be converted to a DC signal. The temperature input is linearized and amplified, and then passed through an optocoupler to the output stage. Full 3-way isolation (input, output, power) make this module useful for ground loop elimination, common mode signal rejection, and noise pickup reduction.
