Technical Data

General

The thermostat CO 9000 is a microprocessor controlled measuring device especially developed for locomotive applications, for instance to control the oil temperature of a circular course. The thermostat is provided with 4 threshold values. The threshold values and the corresponding hysteresis can be programmed according to the specifications of customers. The temperature is measured by a sensor of the type Pt100. When running, the measured value is monitored. Passing over or falling short of the programmed threshold values will be indicated by a corresponding isolated contact.
