Abstract

This paper proposed one kind of improved design of pressure relay based on optical switch aiming at the problem with pressure relay, for example as large switching value, large deviation of set point, low repeatability, etc. Firstly, the structure and principium of pressure relay was analyzed, also the problems when using which was analyzed. Secondly, the structure and relating circuit of pressure relay was improved by setting the value of pressure with the reflective optical switch based on the precision pressure gauge. Experimental results of comparing test shows that it was obviously reduced with the switching value, repeatability and set point deviation when using pressure relay based on optical switch. The improving method proposed in this paper was feasible.
