A Non-Invasive Oil Temperature Measurement Technology Based on Heat Transfer Model

Abstract:

Oil temperature plays a key role in state monitoring and fault diagnosis of hydraulic systems. Traditional methods for measuring oil temperature are neither convenient nor safe. In this paper, a non-invasive test technique together with its calculation model for obtaining fluid temperature is proposed by measuring the pipe surface temperature and the ambient temperature. A series of experiments had been carried out on different pressure values, and the oil temperature calculation model proposed was optimized accordingly. Experimental results show that this measurement technique together with the model can provide a fast and accurate way of oil temperature testing non-invasively under different pressure conditions, so it can be introduced to the hydraulic system application.
