Abstract

A portable device for adjusting and calibrating buoy level gauges, comprising a bracket consisting of a threaded sleeve with a plate fixed to it having a block wheel rotating on an axis, the bracket being mounted on a gauge body on a standard thread, characterized in that a cable is thrown through the block wheel , one end of which is attached through a hook to a stepladder with a buoy, and the other end is attached to a set of loads, with the axis of the cable and the axis of the stepladder with the buoy coinciding.

Description

The device relates to the field of measuring instruments, in particular to devices for tuning and calibrating buoy level gauges.

A device is known for calibrating level sensors (see patent for a utility model of the Russian Federation No. 40108, 11/19/2003), including a level-equipped circuit board with a movable horizontally mounted shaft, at one end of which a limb equipped with a flywheel is fixedly mounted, and a platform for placement at the other calibration sensor, while the board is mounted on a suspension with adjusting screws, the disadvantage of which is the high complexity of the adjustment and calibration of buoy level gauges during their operation.

A device for monitoring load sensors (see patent for utility model of the Russian Federation No. 15934, 05/05/2000), comprising a bed in the form of a base plate mounted on columns, on which a node is mounted for securing monitored sensors with means for applying force and registration, and a lifting mechanism with a device for alternately loading the sensor with exemplary weights made in the form of disks. The disadvantage of this device is the inability to ensure the installation of the operating range of the strain gauge used in the device for tuning and calibrating buoy level gauges.

The closest analogue is the device described in the technical description and operating instructions 08919250 TO "Sapphire-22DU-Vi and Sapphire-22DU-Ex measuring level converters" and the method for setting up buoy level meters (see "Technical description, operating manual 003192250TO "). This device comprises a housing, a bed with adjusting retractable supports, racks with an upper base for installing a strain gauge transducer, a set of loads with suspension, a measuring unit, a power supply and a strain gauge output signal meter.

The disadvantage of this device is that it does not allow to provide the required accuracy for the adjustment of the buoy level gauges directly at the place of installation, which reduces labor productivity when setting up and calibrating the level gauges.

The technical result of the claimed device is to increase labor productivity through the use of a portable device for tuning and calibrating buoy level gauges such as "Sapphire - 22DU" directly at the place of installation. This eliminates damage to the settings during installation (dismantling) and transportation of the level gauges for their adjustment in the laboratory.

Figure 1 shows a portable device for tuning and calibrating a displacer level gauge.

In figure 2. A bracket for a portable device with a quotation element is shown.

The inventive device is a bracket consisting of a threaded sleeve 5 with a plate 7 fixed on it, on which a wheel of a block 9 is mounted, which rotates on the axis 10. The bracket is mounted on the housing of the level gauge 2 on a standard thread, with a cable 8 thrown over the wheel of the block 9, one end of which is attached through a hook 4 to a stepladder 3 with a buoy 1, and the other end is attached to a set of loads 11, and the axis of the cable 8 and the axis of the stepladder 3 with a buoy 1 coincide.

A portable device for setting and calibrating the buoy level gauges works as follows.

Before starting work, the position of the bracket is adjusted to align the axis of the cable 8 with the axis of the ladder 3 with the buoy 1. To do this, throw the cable 8 with the set of weights 11 through the wheel of the block 9 and adjust the plate by moving the plate 7 with the loose screws 6.

Further, the adjustment and calibration of the buoy level gauge is carried out according to the operating instructions for the device - 08919250 TO, setting the necessary load 11 and adjusting the output current of the buoy level gauge.

With the weight of the load P = 0, the output current of the level gauge A = 4 mA.

With the weight of the load P = the weight of the liquid displaced by the buoy (maximum), the output current of the level gauge is A = 20 mA.
