Oil pressure level display, esp. for internal combustion engine - has evaluation circuit computing desired pressure from engine revolution rate and oil temp.

摘要

The oil pressure display arrangement contains a press. sensor and a display device and/or a warning device. An evaluation unit connected to the sensor and display and/or warning device contains a computer which computes the desired oil press. from the revolution rate of the machine unit whose oil level is being monitored and the oil temp. The computer can contain a characteristic field enabling the desired oil press. to be derived from the revolution rate and oil temp. signals. ADVANTAGE - Is improved to give reliable indication of true oil press. at each operating point.
