overview

Drip control instrument is an intelligent instrument specifically designed to provide quantitative automatic control for valve packaging machines in chemical, grain, cement and other industries. This table adopts industrial grade component design, color LCD display, surface mount technology production, multiple anti-interference measures, and new research results of multiple microcontrollers. It has the characteristics of good human-machine interface, powerful functions, high reliability, and strong adaptability. The application of numerous new technologies has made instruments have outstanding advantages in product reliability, flexibility of use, and ease of operation, and can be reliably used in complex and harsh environments.

Functional Features

1. Working power supply: 24VDC.

2. Working environment:- 10-50 ℃/10-95% RH (no condensation).

3. Weight detection: The resolution is 16 bits, the input sensitivity is 0.2-1.0 μ V/d (according to the factory set gain), and the error is less than 0.01%.

4. Instrument comprehensive error: less than 0.02%.

5. Monitor: LCD display, resolution: 320 * 240.

6. Display digits: 5 digits.

7. Analog input channel: 16 bit, 2CH, adjustable gain. CH1 can be directly connected to the load sensor, and the instrument provides a 10V/200mA power supply for the sensor; The CH2 input signal is a 0-20mA or 4-20mA current signal.

8. Analog output channel: 12 bits, 2CH. Dual analog output: Both CH1 and CH2 can choose 0-20mA, 4-20mA, 0-5V, 1-5V output

The upper and lower limits can be set, and the load is less than 600 ohms.

Junction box+3, 4 weighing modules (including upper and lower mounting boards)

A weighing sensor is a device that converts a mass signal into a measurable electrical signal output.

According to the conversion method, it can be divided into 8 categories: photoelectric, hydraulic, electromagnetic, capacitive, magnetic pole transformation, vibration, gyroscope ritual, resistance strain, etc. Resistance strain is widely used.

There are several styles of resistance strain gauges, including S-type, cantilever type, spoke type, plate ring type, membrane box type, bridge type, column tube type, etc.

The difference between skinning and zeroing:

Gross weight=tare weight+net weight

Reset: Set installation complete

Afterwards, the operation performed when the tank (platform, bucket) is empty is similar to the PV reset after our pressure transformation is completed. (Zero setting of equipment)

Peeling: There are practical process requirements, and some production processes require obtaining gross and net weight values. Usually operated under tare weight conditions.

The instrument will display both gross and net weight. (Zero setting of process)

Drip controller, ingredient controller

Support: Three specifications of wall mounted, cast aluminum explosion-proof cabinet, and stainless steel explosion-proof cabinet

Usage: Ingredients for chemical, intermediate, and pharmaceutical industries

Using the signal from the weighing tank (weighing sensor) to evaluate the current feeding (or discharging) amount, the feeding (or discharging) rate can be obtained by calculating with time, and compared with the SP value

Perform positional control (batch control) or PID control (quantitative control).

Resolve the accuracy and cost issues of controlling with conventional FLOW METERs (for high quality flow rates). Significantly reduce costs while ensuring high precision.

It is currently the preferred solution for ingredient and drip modification in chemical processes!

We can customize professional control logic to solve the problem of difficult process adaptation for imported products.

Good industrial grade design to meet the anti-interference requirements of industrial sites. Solved the performance issues of other traditional Weighing instruments (mostly civilian and converted from weighing scales).

The explosion-proof shell (explosion-proof button, Toldo uses non explosion-proof button, which poses significant safety issues) is suitable for chemical explosion-proof requirements.
