Abstract

PURPOSE: In a level detector which detects a liquid by a change in the resistivities which is caused by a difference in the temperatures in a liquid phase and a gas phase, when a thermistor having a temperature coefficient generates heat by itself, the level detector is designed to detect a liqid lavel in a wide renge of the temperatures used, by connecting in series temperature compensating thermistors having a temperature coefficient reverse to each other.
