AEM 30-2204 - 4-Channel K-Type Thermocouple Amplifier

Universal 4-Channel K-Type Thermocouple Amplifier by AEM®. This Thermocouple Amplifier provides laboratory-grade accuracy for virtually any on-board temperature measurements. This unit utilizes low-cost K-Type thermocouple amplifiers to measure multiple engine system temperatures with better accuracy and faster response times than currently available temperature-measuring devices.

Features:

• Uses common miniature thermocouple connectors or ANY K-Type thermocouple
• On-board cold junction temperature compensation for laboratory-grade accuracy
• Includes FOUR (4) 0-5v analog outputs
• Measures up to 20C below cold junction temperature
• “Fault LEDs” indicate when a thermocouple is faulty
• High-quality Deutsch connector
• Mating harness included

Unlike common single-channel gauges and amplifiers whose readings can vary up to 20C 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. 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.

John Concialdi and Bob Sullivan co founded AEM in 1987 as a tuning performance shop in Compton California. Both men had extensive technical backgrounds in engines and engine airflow, and in a short time AEM became the go-to company for performance modifications. By 1993, when the company relocated to Gardena California, it had become commonplace to see cars wearing the bright yellow AEM logo winning races. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. AEM can boast a number of firsts and unique products: They’re the first manufacturer to make an intake system with specific tube lengths and diameters to take advantage of pressure waves in the inlet tract; they developed the first dual chamber intake kit; they designed an air bypass valve to prevent hydro-lock should the air filter ingest water; and they created one of the first hybrid intake systems for modified cars. AEM continues to create innovative products to help you get more power from your car.
