Omega ON-970-44030 Immersion Thermistor Sensor

The Omega ON-970-44030 Immersion Thermistor Sensor is a liquid-temperature sensor designed for direct immersion in fluids to monitor temperature with a thermistor element. Its model designation ON-970-44030 and catalog reference #147985 identify a compact immersion probe intended for insertion into vessels, pipes, or process streams where accurate liquid temperature readings are needed. The sensor relies on a thermistor, a resistance-based device whose resistance changes with temperature, allowing it to output a measurable signal that can be read by compatible instruments. This design supports straightforward integration with standard temperature monitoring equipment, including data loggers, meters, PLCs, or temperature controllers, making it suitable for laboratory and industrial environments. Proper immersion of the sensing tip is essential for accurate readings, and users should consult official Omega wiring and installation guidelines for correct electrical connections. The ON-970-44030 designation confirms this unit as Omega's immersion thermistor solution for liquids.
