Frequently Asked Questions
Engineering answers to the questions our customers ask most often.
An automotive coolant level sensor monitors the coolant reservoir to warn the driver before coolant drops below the safe minimum — preventing engine overheating and head gasket failure. Sensing Technologies manufactures capacitive non-contact coolant level sensors that detect fluid level through the reservoir wall without any wetted parts, rated ±2 mm accuracy, –40°C to +125°C, IP67/IP68. No moving parts means no mechanical wear over the vehicle's lifetime. IATF 16949:2016 certified.
