ABSTRACT:
To solve the problem that the prior device has a difficulty in performing accurate measurement of weight or dimension of a work which is placed in a furnace, the invention provides a device for measuring the physical state of the work under high temperature conditions such as a sintering furnace, which comprises: a frame for holding a work; a base on which the frame is placed; a probe having an end portion disposed for relative movement between the work and the frame; a step motor for driving the probe so that the end portion of the probe moves between the work and the frame and also lifts the frame together with the work away from the base; a microcomputer which acts together with a magnetic scale and a load cell to send a control signal to the step motor, thereby detecting a displacement of the probe and a load imposed on the probe.
