R300 Series Temperature Sensor DESCRIPTION Other potential applications for this harsh duty sensor may The R300 Series is a passive, resistive temperature device include fluid or air temperature sensing within the engine (RTD), high temperature probe. This product features a robust, environment or in industrial applications such HVAC or stainless steel closed-tip design that enhances reliability in refrigeration compressor equipment where this type of sensor aggressive environments, while still providing excellent packaging and temperature range is often ideal. response time. This one-piece sensor with integral connector was designed for use in heavy duty vehicle engine exhaust gas recirculation (EGR) systems where temperature excursions to 300 °C [572 °F] can occur. FEATURES POTENTIAL APPLICATIONS • Working temperature range: -40 °C to 275 °C • Exhaust gas temperature sensing systems on heavy duty, [-40 °F to 527 °F], continuous, excursion to 300 °C [572 °F] truck, agriculture and construction vehicle engines including: for 10 min. max. − In-line fluid temperature sensing • Response time: T63; at 10 m/s gas flow rate at 150 °C − Cylinder head temperature sensing [302 °F] ~15 s • High temperature industrial or commercial applications • Accuracy: better than ±3 °C, -40 °C to 300 °C including: [-40 °F to 572 °F] typical − Bulk refrigeration • M14 x 1.5 mounting thread − Domestic heating and controls • Enhanced reliability − Hot tub and pool temperature controls • Linear output − Industrial ovens up to 300°C [572 °F] • Long life
