UVDT
UVDT
The UVDT device is designed to reproduce deformations at high temperatures, specifically for determining parameters of strain gages such as gage factor, creep, and mechanical hysteresis within a temperature range of 20 to 1000°C.
Structure and Parameters
The device operates by deforming a beam of constant cross-section through pure bending. It includes a loading device, graduation beam, beam heating system, strain measuring device, and deflection meter. The loading device features a frame with fixed and movable traverses equipped with rollers for beam installation. The TP-002T strain measuring device is used for multipoint measurements and signal conversion. The graduation beam is made from a material with a high limit of proportionality, and its temperature is controlled by a thermoelectric transducer. Data collection and processing are automated via dedicated software on a PC.

UVDT Device for reproducing of deformations at high temperatures Pic. 1 – Overview photo of UVDT tool (without graduation beam installed) 1. General information The UVDT device for reproducing of deformations at high temperatures (hereinafter - Device) is dedicated for determination of parameters of strain gages such as: gage factor, creep and mechanical hysteresis in the temperature range from 20 to 1000°C. 2. Structure and parameters of the Device The principle of operation is based on the deformation of a beam of constant cross-section (graduation beam) by the scheme of pure bending. Depending on the deflection of the beam, the relative deformation of the lower and upper surfaces of the beam is being determined. The Device consists of a loading device, graduation beam, beam heating system, strain measuring device and deflection meter. The loading device consists of a frame, a fixed traverse fastened to the frame, and a movable traverse. Each traverse is equipped with rollers, between which a calibration beam is installed.

As the movable traverse moves upwards, the upper fibers of the calibration beam are compressed, while the lower ones are stretched. Deformation of the beam is set using the deflection meter indicator installed on the beam surface. TP-002T strain measuring device is used for multipoint measurements of static signals of strain gauges (relative change in resistance of strain gauges) and conversion of an analog signal into a digital one. The graduation beam is made of a material that has a high limit of proportionality both at room and at elevated temperatures. When the beam is heated by electric...
