APD 4002 RTD or Thermistor Temperature Transmitters
RTD or Thermistor Input to DC Isolated Transmitter
The APD 4002 accepts an RTD or thermistor 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. A custom RTD or thermistor can be set up with customer provided sensor data. Microprocessor-based linearization uses 41 to 55 segmentsor up to a 14th order polynomial depending on the sensor type. The input is sampled, digitally converted to a linearized temperature signal 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. The low noise 18 bit analog output is isolated and can be set for common voltage and milliamp output types.
