FIELD: test engineering; measurement technology.
SUBSTANCE: indicator can be used as detector of presence of fluid in containers, in particular, in high-voltage discharge conduits of different purpose diesel engine. Indicator has housing, radiation source, reflector, radiation receiver and signal processing unit. There is working cavity in central part of the case. Reflector is disposed inside the cavity onto frame with two parallel channels. Radiation source is disposed in one channel and radiation receiver - in the other one. Radiation source and radiation receiver are connected with signal processing unit fastened to top part of plate. Plate is disposed inside case under frame. There hole for feeding fluid at lower part of side wall of working cavity. There is drainage hole in top part side wall of working cavity. Top cap of the cavity is made in form of screw. Frame is connected with case by thread.
EFFECT: simplified design; reduced cost.
