Details
The Koolance SEN-AP008G is a coolant temperature sensor plug: a 10K Ohm thermistor in a G1/4" BSPP plug that screws into any free G1/4" port of the loop and reads the coolant temperature directly. It works with Koolance multi-sensor systems that use 10K Ohm sensors, and comes with a 76 cm (30") cable.

Coolant temperature right in the loop
The thermistor tip reaches into the coolant, so the sensor measures the liquid itself rather than the surface of a part. Screw it into any free G1/4" port on a block, radiator, reservoir or fitting body; an O-ring under the knurled head seals the thread.
For Koolance multi-sensor systems
Koolance makes this sensor for its own controllers and displays that use 10K Ohm @25°C sensors, first introduced in 2011. Older Koolance products use 50K Ohm sensors and do not read this sensor correctly. In its stock form the sensor plugs into Koolance multi-sensor systems; using it with other temperature inputs needs a modification.
Accurate thermistor
Koolance publishes the full resistance-temperature table for the SEN-AP008G from -40°C up. The thermistor has a resistance of 10 kOhm ±1% at 25°C and a B25/85 value of 3,435 K ±1%.

Notes
- Any modification to this sensor voids its warranty and makes it non-returnable.
- Koolance recommends not using aluminum together with bare (unplated) copper or brass in the same loop, and not using silver together with nickel.
