R300-F35-M14-C

## R300 Series 

## Temperature Sensor 

## **DESCRIPTION** 

The R300 Series is a passive, resistive temperature device (RTD), high temperature probe. This product features a robust, stainless steel closed-tip design that enhances reliability in aggressive environments, while still providing excellent response time. 

Other potential applications for this harsh duty sensor may include fluid or air temperature sensing within the engine environment or in industrial applications such HVAC or refrigeration compressor equipment where this type of sensor packaging and temperature range is often ideal. 

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** 

- Working temperature range: -40 °C to 275 °C 

- [-40 °F to 527 °F], continuous, excursion to 300 °C [572 °F] for 10 min. max. 

- Response time: T63; at 10 m/s gas flow rate at 150 °C [302 °F] ~15 s 

- Accuracy: better than ±3 °C, -40 °C to 300 °C [-40 °F to 572 °F] typical 

- M14 x 1.5 mounting thread 

- Enhanced reliability 

- Linear output 

## **POTENTIAL APPLICATIONS** 

   - Exhaust gas temperature sensing systems on heavy duty, truck, agriculture and construction vehicle engines including: − In-line fluid temperature sensing 

   - Cylinder head temperature sensing 

   - High temperature industrial or commercial applications including: 

   - Bulk refrigeration 

   - Domestic heating and controls 

   - Hot tub and pool temperature controls 

   - Industrial ovens up to 300°C [572 °F] 

- Long life
