temperature amplifier for automotive

Hi,

I had swap “FJ cruiser panel” installed into “Hilux” but Temp indicator is not function because FJ panel required amplifier.

  • FJ wiring use thermistor sensor @ 25-40 Celsius (1.7 to 2.1V=>1.3 to 1.8 V) send signal to Amplifier and output 11- 14 V for panel temp indicator.
  • Hilux already has thermistor sensor @ 25-40 Celsius (1.35 to 1.75V=>0.85 to 2.34V) directly to panel.

 

Could someone help/advise to select Amplifier that matching with FJ panel.

Option 1: Use Hilux thermistor sensor send signal to new Amplifier and send to FJ panel.

Option 2: Hilux panel has Pulse generation output data signal. Can use this signal to FJ panel.

Thank you.
