AEM 30-2204
Unlike common single-channel gauges and amplifiers whose readings can
AEM 30-2204 vary up to 20? C from actual temperatures, AEM guarantees its 4-Channel K-Type Thermocouple Amplifier to read better than 1% full scale, even at the extremes of the temperature range! The unit achieves its laboratory-grade accuracy via a 100% surface-mounted PCB (printed circuit board) that has four differential temperature inputs fed into an A/D converter and fitted using a stage-three, eighth-order polynomial curve fit K-Type sensors sold separately. The amplifier then compensates for this value using AEM’s on-board cold junction temperature measurement, and then sends the temperature outputs on feedback-monitored 0-5v analog outputs and an RS-232 serial data stream Includes FOUR (4) 0-5v analog outputs On-board cold junction temperature compensation for laboratory-grade accuracy ... »»
