AE70 differential pressure transmitter pollution alarm

The AE70 differential pressure transmitter is an instrument used to measure the difference between two pressures. Its working principle is to measure the pressure difference of the fluid in the pipeline, thereby achieving monitoring and control of fluid flow rate, flow rate and other parameters. When the filter element in the filter gradually becomes clogged due to intercepting pollutants in the system, the pressure difference between the inlet and outlet will increase, and the pressure difference transmitter can display this pressure difference. When the pressure difference increases to the set value of the transmitter, the pressure difference transmitter will automatically send a signal to remind the operator to clean or replace the filter element to ensure the safe operation of the system. As a professional product in this field, AE70 differential pressure transmitter is widely used in industries such as petroleum, chemical, power, metallurgy, etc. for precise measurement and control of flow rate.

It should be installed at the highest possible position and installed vertically, with the pressure input port facing downwards, and the installation inclination angle should be less than 15 °.

It should be installed in a location that can avoid dust and soil pollution, away from high-voltage cables and equipment on the engine, and cables should be avoided from being arranged parallel to high-voltage cables.

The installation position should ensure easy maintenance and disassembly of the sensor for future maintenance.

Installation steps for AE70 differential pressure transmitter:

When the pressure port is first installed, the maximum allowable radial installation force for the high-pressure end is 80N, and for the low-pressure end it is 40N. During normal operation, the maximum allowable radial force on the high-pressure end is 40N, and on the low-pressure end it is 20N. M6 fastening screws should be used for installation, with a tightening torque of 8 ± 2Nm.

The rubber hose and metal conduit connecting the sensor should continuously descend and should not have a U-shaped structure.

Ensure that no water vapor or other impurities accumulate inside the sensor, and the electrical connections of the sensor should avoid exposure to high temperature environments.

Use and maintenance of AE70 differential pressure transmitter:

Regularly check the working status of the differential pressure transmitter to ensure accurate measurement and normal signal output.

When the differential pressure transmitter sends a blockage signal, the filter element should be cleaned or replaced in a timely manner to ensure the safe operation of the system.

Avoid severe impact and vibration on the differential pressure transmitter to avoid affecting its measurement accuracy and service life.
