B MOTORPORT COMPONENT B TEMPERATURE ENOR Purpose and unction Temperature sensors used in modern engine management systems are of NTC [negative temperature co-efficient] design. imply as temperature rises the resistance of the NTC element reduces. These sensors are used for their logarithmic resistance characteristics as well broad sensitivity range. These sensors are designed for use in a broad range of purposes and applications involving temperature of water or oil. Air temperature can be measured with sensor number 0 80 0 085. or more detailed information about these products refer to our website www.bosch.com.au TEMPERATURE ENOR TECHNICAL DATA Max Circuit Measurement Characteristic Current Thread Part Number Range Curve [A] ize Connector igure Comment 0 80 0 0-40 to + 0 A.0 M x.5 9 067 0 A or fuel, oil and water 0 80 0 06-40 to + 0 A.0 M x.5 9 067 0 A or fuel, oil and water 0 80 0 0-40 to + 0 A.0 M x.5 9 067 0 A Dual Element - water 0 80 0 09-40 to + 0 A.0 M x.5 9 067 0 A or air temperature 0 80 0 085-40 to + 0 B.0 --- 9 067 0 B or air temperature ig.

This mixture is produced by sintering and pressing with the addition of binding agents. or automotive applications, NTC resistors are enclosed in a protective sheath. If NTC resistors are exposed to external heat, their resistance drops drastically and, provided the supply voltage remains constant, their input current climbs rapidly. This property can be utilised for temperature. NTC resistors are suitable for an extremely wide range of ambient conditions, and with them it is possible to measure a wide range of temperatures. Installation instructions Installation is to be such that the front part of the sensing element is directly exposed to the air flow.
