Calibration device of pull-press integrated sensor

Abstract

The invention relates to a calibration device of a pull-press integrated sensor. The calibration device of the pull-press integrated sensor comprises a rack, wherein a loading mechanism is assembled on the top of the rack. The loading mechanism comprises a driving device and an executing mechanism, wherein the executing mechanism is connected with the driving device and used for outputting up-and-down straight line motion. The executing mechanism comprises a dowel bar, wherein the dowel bar is arranged at the tail end of the executing mechanism, a standard pressure sensor is arranged on the dowel bar, a base seat which is used for supporting and holding a to-be-demarcated pressure sensor is assembled at the tail end of the dowel bar. A baffle is arranged on the upper portion of the base seat. The baffle is assembled on the dowel bar of the executing mechanism anti-dropping in a dipping-and-heaving mode. A first connector which is used for being connected with one end of a to-be-demarcated tension sensor is fixedly connected on the baffle. The first connector and the baffle are in driving connection synchronously in the same direction when the to-be-demarcated device works. A second connector which corresponds to the first connector is assembled on the lower portion of the base seat on the rack. The calibration device of the pull-press integrated sensor is capable of carrying out demarcating to a tension sensor and a pressure sensor at the same time, convenient and swift, simple in structure and capable of improving demarcating efficiency.

Description

technical field [0001] The invention relates to a calibration device for calibrating the tension and pressure of a sensor, in particular to a calibration device for a tension and pressure integrated sensor. Background technique [0002] Tensile pressure sensor, also known as resistance strain sensor, belongs to the load cell series and is a device that converts physical signals into measurable electrical signal outputs. The tension and pressure sensor uses an elastic body as the intermediary, through the force acting on the resistance strain gauges on both sides of the sensor to change its resistance value, and then convert it into an electrical signal through the corresponding circuit, so as to realize the control. Its advantages are high precision, wide measurement range, long life, simple structure and good frequency response characteristics. The tension and pressure sensor is a key part of the force measuring equipment, so its calibration is an important link to ensure ...

Problems solved by technology

[0005] Existing calibration of tension and pressure sensors generally uses professional equipment such as benchmark dynamometers and piston pressure gauges. These equipment not only have high maintenance costs, but usually only one of the tension or pressure sensors can be calibrated, and the volume of the equipment Large, there are certain requirements for the space of the use environment, which cannot meet the requirements of on-site calibration for most measurement conditions; there are also some relatively simple tension and pressure calibration equipment such as force measuring weights, which can only calibrate tension Or one of the pressure sensors, and this kind of equipment is greatly affected by human influence (loading position, loading method, etc.), and it is difficult to meet the requirements of on-site calibration of tension and pressure sensors
