Abstract

The invention provides a resistance strain regulator which comprises an input module, a stored program control gain module, a voltage-current conversion module and an output module. The stored program control gain module is used for regulating the number of times of magnification, and magnifying a micro electric signal. The number of times of magnification can be regulated through a program. Selection can be carried out among a plurality of numbers of times of magnification in a large range. The resistance strain regulator has the advantages of solving the problem that the number of times of magnification of an existing resistance strain regulator is small and single, having a voltage output mode and a current output mode, and therefore satisfying practical application of industry.

Description

technical field [0001] The invention relates to a strain regulator, in particular to a resistance strain regulator. Background technique [0002] At present, the common resistance strain conditioners are large in size, not easy to carry, and are not conducive to multi-node distributed measurement or group measurement, and the magnification is small or single, which cannot meet the amplification operation of small strains. In addition, the existing The strain conditioner has a single output form and can only output strain voltage signals, which is not conducive to industrial practical applications. Contents of the invention [0003] Aiming at the problem that the current resistance strain conditioner has a small magnification or a single magnification and can only output strain voltage signals, the present invention provides a resistance strain conditioner, which can achieve a larger magnification and has more magnifications. Optional, can also output the strain current si...
