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

The 4-Channel K-Type Thermocouple Amplifier is ideal for users who want to accurately monitor multiple engine system temperatures, including water, air, coolant, fuel, disc brake and more! Multiple channels allow you to use each amp to simultaneously read different system temperatures (one channel for EGT, one channel for CLT, etc.). Users can utilize ANY K-Type thermocouple including commonly-available miniature thermocouple connectors, and datalog the readings via an RS-232 serial data stream (programmable EMS not required for datalogging). This unit does not include K-Type sensors; however K-Type sensors will be available from AEM in the near future.

Unlike common single-channel gauges and amplifiers whose readings can vary 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 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.

AEM 4-Channel K-Type Thermocouple Amplifier Features:

  • Works with ANY K-Type Thermocouple
  • Uses common miniature thermocouple connectors
  • On-board cold junction temperature compensation
  • Includes FOUR (4) 0-5v analog outputs
  • RS-232 serial port included for datalogging (programmable EMS not required)
  • Fault LEDs? indicate when a thermocouple is faulty
  • High-quality Deutsch connector
  • Mating harness included

Import duties, taxes, and fees aren't included in the item's price or shipping costs. The buyer is responsible for paying for any import fees. Check with your country's customs office to find out what these additional charges will be before you bid or buy.

We utilize USPS, FedEx and UPS for outbound international shipments. If you have a preference in regards to which shipping company we utilize to fulfill your order please make note of it with your payment or in a follow up email. For example, Canadian customers generally prefer USPS as we have heard that FedEx charges additional brokerage fees. On the other hand, many customers from the United Kingdom prefer FedEx as there are no additional fees and they receive their packages significantly faster than those shipped via USPS. Please feel free to contact us for additional information.
