Product Details

Digital differential transmitterAdvantage:

1. High reliability

Most faults in wired networks are caused by connectors, while wireless systems rule out such a possibility. In addition, the continuous advancement of raw material technology enables integrated wireless sensor systems to meet the durability and reliability requirements of wireless communication technology in harsh industrial environments.

2. Low cost

Compared to the cost of wired installation, maintenance, fault diagnosis, and upgrading wiring.

3. Usability

An integrated wireless sensor system with distributed intelligence can independently control industrial processes from the operator.

4. High flexibility

Without the constraints of cables, factory managers can easily configure assembly lines to adapt to changing user needs and better track the production process.

5. Integrated MEMS technology

Micro electromechanical systems (MEMS) provide enormous application prospects and economic benefits in terms of sensing capabilities, while integrated wireless modules and sensors can avoid faults caused by the large number of cables attached to micro devices. As the volume of wireless sensors continues to shrink, such advantages will show a significant growth trend.

6. Security

With the development of technology and the continuous emergence of new threats, the ability to upgrade security maintenance is *. The new encryption strategy and covert data transmission indicate that the security level of wireless systems will surpass that of wired systems.

7. Short construction period

Wireless sensor systems can quickly build effective communication networks through the self-organizing and self configuring functions of nodes.

Precautions for using digital differential transmitters;

1. During installation, there is often looseness. The transmitter is connected to the three valve group, and the bolts should be tightened diagonally. Generally, they cannot be locked at once. When installing the three valve group, the sealing coil should be encrypted.

2. Set the function items of the calibrator. First, reset the calibrator to zero, connect the pressure pipeline, and pay attention to the positive and negative pole connections. Connect the standard resistor. Check the circuit current.

3. Correctly connect the receiver operator, set the transmitter content according to requirements, and adjust the zero position.

4. For the operation of the three valve group: first open the balance valve and correctly open the high-pressure valve.

5. Accuracy verification of transmitter: Place the fine adjustment valve in the middle position, close the shut-off valve and the check valve, set the output pressure of the electric pressure test bench, calibrate the basic error (up 5 points, down 5 points), and record data in a timely manner.

6. Correctly calculate errors and backlash, provide correct verification conclusions, provide correct verification conclusions, and handle significant figures correctly.

7. Equipment reset and organization: Stop using the three valve group, cut off power, remove circuit connections and related equipment, start and close the pressure control console, and pay attention to operating according to regulations while opening the shut-off valve and check valve for maintenance.
