The Temperature Sending Unit 1/2 NPT is a precision instrumentation component designed for automotive and industrial cooling system monitoring. This sending unit converts engine coolant temperature into an electrical signal for dash-mounted temperature gauges, making it useful for monitoring engine performance and preventing overheating.
The 1/2-inch NPT male thread fitting integrates seamlessly into factory or custom cooling systems, providing reliable temperature feedback across a wide range of operating conditions. Built by Classic Instruments, this sending unit employs a thermistor-based sensing element that delivers accurate temperature readings proportional to coolant temperature.
Technicians, hot rodders, and fleet operators can benefit from this sending unit when upgrading older gauge systems or replacing failed temperature sensors. Installation is straightforward: thread the unit into the designated 1/2 NPT port and connect the sender wire to a compatible gauge.
