This sensor is for measuring engine water and oil temperatures. Unlike most oil/water temperature sensors on the market that use thermistor sensing elements, this sensor uses a RTD sensing element. The advantage of the RTD is increased accuracy and wider temperature range. When used with our SYL-1813 gauge, you will be able to measure from -199 C to 250 C (or -199F to 500F) with less than 1 degree error.  No other water/oil temperature gauges can match its performance. In addition, you will be able to use all of SYL-1813’s advanced features, such as max/min temperature recall function and programmable control output.

This sensor is about the same length as the VDO water/oil temperature sensor with 1/8 NPT mounting. It can be used for ports that the VDO sensor uses. However, if you are using a plug adapter to mount the sensor into the oil gallery located on the back of the engine block, you might need a longer probe as show as the optional longer sender in the picture below. Click here for the longer sender.
