SENSITIVE ZERO-THERMOSTAT Russian patent published in 2008 - IPC G01K7/02 

FIELD: the invention refers to measuring technique and is applied for thermostatting of controlling soldered joints of differential thermocouples.

SUBSTANCE: the thermostatting controlling soldered joint of a differential thermocouple is located in the point of intersection of the central fibers of the capron net in the inner cavity of the float nearby the upper foundation. Its connecting wires placed in a special isolating screen are taken out outside through a packing. Two other differential thermocouples are fastened to the net, at that the supporting and the controlling soldered joints of the corresponding differential thermocouples are placed diagonally. The sensors of temperature are fixed to the lateral wall of the inner cylindrical chamber and are located on one line along the vertical axle perpendicularly to the plane of the border of division of phases. At that the second sensor is located in the central part of the cylindrical chamber and two others are places on an equal distance nearby the upper and the low foundations of the inner cylindrical chamber correspondingly.

EFFECT: expands functional possibilities.
