The temperature sensor uses an NTC thermistor element to measure coolant, engine oil, and transmission oil temperature. It must be paired with progauges temperature gauges, with the resistance–temperature curve matched at the factory before shipment for direct correspondence with progauges digital and mechanical temperature displays, and customization is available. Suitable for heavy-duty trucks, buses, agricultural machinery, construction equipment, forklifts, and generator sets. Available for OEM / ODM development.
