Universal 4-Channel K-Type Thermocouple Amplifier by AEM®. Get laboratory-grade accuracy for critical vehicle system temperatures like oil, air, coolant, disc brake, etc. with the 4-Channel K-Type Thermocouple Amplifier. Unlike single channel gauges whose readings can vary as much as 20°C from actual temperatures, AEM guarantees this amplifier to read better than 1% full scale, even at the extremes of the temperature range. It utilizes low-cost K-Type thermocouples (not included) to measure temperatures from 32°-1832°F (0°-1000°C), and outputs to an aftermarket Electronic Control Unit or any other device that can accept 0-5V analog outputs for analysis or logging. Data can also be output to datalogger, laptop/PC via RS-232 output. Includes mating harness and instructions.

AEM Warranty About AEM

Features:

  • Guaranteed laboratory-grade temperature accuracy, even at the extremes of the temperature range
  • Allows accurate monitoring of critical vehicle system temperatures like oil, air, coolant, disc brakes, etc
  • 32°-1832°F (0°-1000°C) temperature range
  • On-board cold junction temperature compensation for laboratory-grade accuracy
  • Measures up to 20°C below cold junction temperature
  • Much more accurate than single channel gauges and amplifiers, whose readings can vary as much as 36°F (20°C) from actual temperatures
  • Uses any K-Type thermocouple with common miniature thermocouple connectors (not included)
  • Includes four 0-5V analog outputs
  • RS-232 serial port included for datalogging (programmable engine management system not required)
  • Includes “Fault LEDs” that indicate when a thermocouple is faulty
  • High quality Deutsch connector
  • Mating harness included

Getting the most accurate temperature data possible is vital for racing vehicles run at the extreme limits, where the difference between finishing a race and a DNF may be a matter of a few degrees. Unfortunately, conventional single channel gauges can have readings that vary up to 20°C from actual temperatures, and may cause you to believe a system is okay when in fact it’s overheated. This type of misinformation can not only result in a lost race, but serious vehicle damage as well. To get temperature data you can trust, for oil, air, coolant, disc brake and more, you need the AEM 4-Channel K-Type Thermocouple Amplifier. It provides laboratory-grade accuracy for virtually any on-board temperature measurements.

The 4-Channel K-Type Thermocouple Amplifier can measure temperatures from 32°F to 1832°F (0°C to 1000°C). It utilizes low-cost K-Type thermocouples (not included), a type of temperature sensor, to measure multiple vehicle system temperatures with better accuracy and faster response times than currently available temperature measuring devices. In fact, AEM guarantees the 4-Channel K-Type Thermocouple Amplifier to read better than 1% full scale, even at the extremes of the temperature range.

This unit gets its laboratory-grade accuracy via a 100% surface-mounted printed circuit board that has 4 differential temperature inputs fed into an A/D converter and fitted using a stage-3, 8th 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.

Multiple channels allow this amplifier to simultaneously read different system temperatures. Any K-Type thermocouple with common miniature thermocouple connectors can be used to provide input. The unit is designed either for integration into vehicles already fitted with aftermarket ECUs or other devices that can accept an analog signal for analysis or logging. AN RS-232 output is also available to allow other programmable devices to use or display the thermocouple temperature data.

The 4-Channel K-Type Thermocouple Amplifier is compact and lightweight, and comes with a mating harness. It includes fault LEDs that indicate when a thermocouple is faulty. The unit can be mounted in the engine compartment or under the dashboard, and secured with Velcro or using the mounting holes. Comprehensive instructions are included, and the amplifier is backed by a limited 1-year warranty.

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.
