One of the finest EGT Gauge Systems for aircraft is manufactured by California based J.P. Instruments and branded as the 'Classic Scanner' – an EGT gauge that is perfect for any plane and especially for those pilots with a smaller budget.
The Classic Scanner EGT Gauge features a large red LED display readout of the temperature as it scans through each cylinder of your plane’s engine. EGT and CHT are both available and alarms are a standard feature. The pilot can select to monitor the temperature in degrees Centigrade or Fahrenheit. Coupled with J.P.I’s famous super accurate fast response probes, the Classic Scanner® (EGT Gauge System) also can let you know about shock cooling before it’s too late! The Classic Scanner® is FAA TSO approved and comes with a one year limited warranty.
Specifications:
The Classic Scanner EGT Gauge monitors every probe three times a second and can monitor up to 16 probes. This indexing rate can be adjusted from one every 1.5 seconds to 1 every 9 seconds. The EGT Gauge accurately converts the thermocouple’s millivolt signal to a temperature on the display. The thermocouple’s millivolt signal is amplified by precision instrument amplifiers which permit the use of fast, grounded type K probes.
A small “c” displayed in the first digit e.g. c370 indicates the unit is scanning Cylinder Head Temperature. A decimal point in the second digit e.g. I.450 indicates temperatures above 1000 F. A display of (say) I.990 indicates
That the temperature exceeds the normal range of 1999 F. The voltage option will display voltage when the STEP button is held. Voltage readings are in tenths of a volt.
Alarm is indicated by a flashing CYL digit for the cylinder that is out of range. In the automatic mode the scan sequence will stop on the out of range cylinder and flash the CYL digit.
Features:
1. The Classic Scanner EGT Gauge System features a large red difficult-to-miss LED display that makes flawlessly easy.
2. Dimming switch to reduce night glare
3. Cylinder number (of the temperature being displayed) is prominently displayed at the top.
4. EGT and CHT readings
5. Pilot controlled alarms.
6. Temperature can be displayed in degrees Fahrenheit or Centigrade
7. Coupled with J.P.I’s famous super accurate fast EGT/CHT response probes.
8. Manual and Auto switch - when the toggle switch is in the Manual position the EGT Scanner will display the current cylinder.
9. Normal leaning is accomplished on the leanest cylinder in the Manual mode which can be found by peaking each cylinder and noting its fuel consumption.
10. In automatic mode temperature of each cylinders will be displayed every four to five seconds in descending order.
11. Alarms are part of the Automatic mode.
12. Day and Night LED brightness options.
So if you are looking for a RPM Sensor that provides the basics with a high degree of accuracy, Classic Scanner EGT Gauge System is the one you would be looking for. More information here: https://www.jpinstruments.com/
