By Type of Fluid
The sensor's response depends on the thermal carrying capacity of the fluid being sensed. Thicker, more viscous liquids remove less heat from the sensor tip, which affects the trip point. Fluid types supported include:
- Water and water/antifreeze coolant — Excellent thermal transfer, clean switching
- Automatic transmission fluid — Moderate viscosity, reliable detection
- Hydraulic fluid — Similar to ATF, requires LS-series die
- Engine oil — Higher viscosity, requires LS12 or LS24 die for reliable operation
