APD 4130/4131 Thermocouple Temperature Transmitters

The APD 4130/4131 accepts a thermocouple temperature input and provides an optically isolated and linearized DC voltage or current output. The thermocouple type, temperature range and output range are factory set. The unit can be set up for all commonly available thermocouple types and temperature ranges. Microprocessor-based linearization uses 41 to 55 segments or 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 16 bit analog output is isolated and can be factory set for common voltage and milliamp output types.
