The VDO 323-803-001-025D coolant temperature sensing unit provides an accurate analog resistance signal (287.4–22.7 Ohm) for monitoring temperatures from +40°C to +120°C in automotive and industrial systems. Built for installation in engine cooling and lubrication circuits with a 1/2-14 NPTF male thread, it supports monitoring of coolant, water, air, engine oil, transmission oil, and fuel, and adds an integrated 103°C warning contact to trigger an over-temperature alert for added protection.

120°C Coolant Temperature Sensor with 1/2-14 NPTF and 103°C Warning Contact
The VDO 323-803-001-025D is a coolant temperature sender for automotive and industrial monitoring systems, designed to provide consistent temperature feedback to a gauge or control system via an analog resistance output. Installed directly into the fluid or air stream with its 1/2-14 NPTF male thread, it supports reliable thermal monitoring across multiple media and includes a 103°C warning contact that closes as temperature rises to help alert operators to overheating conditions.
Compatibility
- Automotive engine monitoring systems
- Industrial engine and equipment monitoring systems
- Coolant circuits
- Water circuits
- Air temperature measurement points
- Engine oil circuits
