Static load weighing module product features and installation matters installation method

The static load weighing module can be divided into three types according to the different assembly methods of the sensor:

Fixed module: The mounting point does not produce a horizontal displacement.

Semi-floating module: The weighing system can be adjusted around the fixed point to eliminate the influence of the container's deformation sensitivity and precision.

Floating module: The mounting point can accurately transfer the bearing capacity to the sensor even in the case of horizontal displacement.

Precautions:

1. Installation precautions

Pay attention to the level adjustment, including the horizontal adjustment between the mounting plane of a single module and a set of weighing modules.

When welding, the sensor can't pass current. When welding the top plate, the ground wire should be connected to the scale body. When welding the bottom plate, the ground

The line is connected to the base, and FANG stops the sensor.

If there is a delivery pipe on the scale body, replace it with a hose or make the connection pipe as long as possible to prevent them from eating.

The sensor's true load causes an error.

A weight calibration table is welded to the container for verification. There is usually no place to place the weight on the container.

Solder a platform to place weights. Usually welding

Below the container, it is easy to place the weight up and down.

The junction box must be protected from moisture and the excess holes should be plugged with a sealing plug. If the junction box is installed outdoors, it must be added

Protect the box from rain. In the event of a failure due to moisture in the junction box, it must happen.

Caused enough attention.

2. Debugging notes:

Before commissioning, be sure to check whether the top nut of the support screw of each weighing module has been loosened.

By the state, otherwise, it will produce a large error, and even can not be weighed.

When debugging, check whether the factory setting value of each parameter meets the actual needs, especially the “power on zero” parameter.

The number is usually set to “automatically clear” when it leaves the factory. On the container scale, it is changed to “boot”.

Clearing to zero, to prevent the weight of the material of the container from being lost and lost when the machine is turned on again due to power failure or the like.

The range setting does not refer to the rated total load of a set of weighing modules, nor the weight of the container itself, but should be based on

Zui large material weighing, from the indexing and dividing values ​​given in the manual, choose the greater than or equal to the weight of the Zui

Range. The power supply voltage of the weighing display must meet the requirements. If the voltage is unstable and exceeds the allowable range, it will cause

Digital drift. Zui is good to use a regulated power supply.

The weighing system consisting of electronic weighing modules facilitates the automatic weighing of the process and facilitates networking with computers.

Therefore, chemical companies will surely get more and more applications.

First, the working principle

Taking a typical chemical reactor weighing as an example, three pressure weighing modules installed at the bottom of the reactor transfer the weight signal of the kettle to the junction box. wiring

The weighing module signals of each road are connected in parallel in the box, and the angular difference can be adjusted according to the load condition of each weighing module, and the collected weight signal is sent to the weighing end or the weight.

Transmitter. The weighing terminal or weight transmitter processes the weight signal into corresponding weight data. For non-professional users, direct use of weighing sensing

The device is very difficult.

Installation method

The static load weighing module can be divided into three types according to the different assembly methods of the sensor:

Fixed module: The mounting point does not produce a horizontal displacement.

Semi-floating module: The weighing system can be adjusted around the fixed point to eliminate the influence of the container's deformation sensitivity and precision.

Floating module: The mounting point can accurately transfer the bearing capacity to the sensor even in the case of horizontal displacement.

Third, weighing module weighing module purchase, installation, debugging notes:

1. Selection considerations

The selection of the weighing module generally selects the range of 3 sets or 4 sets of modules according to the support point of the container. Due to the self-weight of the scale body (container), vibration shock, partial load and the like, generally the following The rules are chosen. Multi-sensor static weighing system:

Fixed load (weighing platform, container, etc.) + variable load (load to be weighed) ≤ selected sensor rated load × number of sensors × 70%, 70% of which is considered in consideration of vibration, shock and partial load factors of.

2. Installation precautions

Pay attention to the level adjustment, including the horizontal adjustment between the mounting plane of a single module and a set of weighing modules.

When welding, the sensor can't pass current. When welding the top plate, the ground wire should be connected to the scale body. When welding the bottom plate, the ground wire should be connected to the foundation to prevent damage.

Sensor.

If there is a delivery pipe on the scale body, replace it with a hose or make the connection pipe as long as possible to prevent them from eating the actual load of the sensor and causing errors.

A weight calibration table is welded to the container for verification. There is generally no place to place the weight on the container, and it is necessary to weld a platform to place the weight. Usually welded under the container for easy weighting up and down.

The junction box must be protected from moisture and the excess holes should be plugged with a sealing plug. If the junction box is installed outdoors, a protective box must be added to prevent rain. In the event of a failure due to moisture in the junction box during use, it must be given sufficient attention.

3. Debugging notes:

Before commissioning, it is necessary to check whether the top nut of the support screw of each weighing module has been loosened, and whether the sleeve is in a free state. Otherwise, a large error will occur or even cannot be weighed.

When debugging, check whether the factory setting value of each parameter meets the actual needs, especially the “power-on zero” parameter. Generally, it is set to “automatically clear” when it is shipped from the factory. Automatically clear at startup to prevent the material weight of the container from being cleared and lost when the machine is turned on again due to power failure.

The range setting does not refer to the rated total load of a set of weighing modules, nor the weight of the container itself, but should be weighed according to the large material of zui, and choose the greater than or equal to the size of the index and the division value given in the manual. Weight as a range.

The power supply voltage of the weighing display must meet the requirements. If the voltage is unstable and exceeds the allowable range, it will cause digital drift. Zui is good to use a regulated power supply.

Because the weighing system consisting of electronic weighing modules facilitates the process automation weighing and is easy to be networked with computers, it is bound to be more and more widely used in chemical companies.
