Product Description

Single Channel Exhaust Gas Temperature (EGT) Amplifier with 0-5V analog output, LCD display and warning light. Includes a thermocouple (sensor).

 

This EGT sensor and amplifier is used to monitor exhaust gas temperature of an engine and displays the temperature live on an LCD display.

 

By monitoring EGT, one can get an idea of the combustion chamber temperature.  Excessive exhaust gas temperature indicates excessive combustion chamber temperature, which often leads to engine damage such as melted pistons.

 

On a petrol engine, EGT sensors are a useful tuning tool when used in conjunction with a wide band oxygen sensor, because unlike a wide band O2 sensor, EGT sensors also show the effects of ignition timing on combustion chamber temperatures. EGT sensors also show the effect of prolonged engine operation at full load and high engine speeds.

 

On a diesel engine, an EGT sensor is arguably the most important sensor to have when tuning for increased performance. Excessive exhaust gas temperatures are essentially the limit of how far the performance of a turbo diesel can be pushed safely. In short, you shouldn’t try to increase the performance of a diesel engine without knowing exactly what the EGT is.

 

While the ultimate set up in EGT monitoring is one EGT sensor per cylinder mounted close to the head, a reasonable cost effective alternative is a single probe fitted into the exhaust manifold collector or on the dump pipe directly after the turbo.  This essentially provides the EGT averaged across all cylinders of the engine. However, if mounted after the turbo, expect the displayed temperature to be up to 200°c cooler than the actual EGT before the turbocharger, so this needs to be kept in mind.

 

For optimum results, individual probes can be installed on each exhaust manifold runner (close to the cylinder head), which then provides information on individual cylinder temperatures. This allows the tuner to make changes to fueling and timing on individual cylinders, rather than to all cylinders as a whole. In order to monitor individual cylinder EGT’s a multiple channel amplifier (and the appropriate number of probes) is required. If you wish to install individual EGT’s, NZEFI has amplifiers available in 2, 4, 6 and 8 cylinders versions available.

 

Single Channel EGT Amplifier Features:

  • Max temperature “Peak hold” display capture capability
  • High set-point alarm LED with internal relay contact
  • 0-5V output can be sent to an ECU to allow modification of the  the tune based on the EGT.
  • °C or °F can be selected
  • Used with K-type thermocouples
  • Display range up to 1300°C
  • Extruded enclosure included. Overall dimensions are 65mm wide x 100mm deep x 35 high and can also be used without the enclosure for permanent installation into dashboards etc. Dimensions of the amplifier without the enclosure are 48mm wide x 75mm deep x 25mm high.

 

EGT Probe Features:

  • 1.8m Integrated  cable with stainless steel braid
  • Probe diameter = 4,75mm (3/16″)
  • Temperature range = -100°C to 1300°C
  • Fast response exposed tip for petrol engines or anti-fouling enclosed tip for diesel engines available
  • Type K thermocouple
