مقدمة

EMT ER Probe can be used to measure metal loss in many areas. It can provide online data about the corrosion rate in the system. The data can check the efficacy of corrosion inhibition or detect corrosivity changes in the system.

What applications are ER Probes suitable for?

They play a crucial role in most intrusive corrosion monitoring applications. The ER Probes are usable in almost any environment, being independent of the process properties.

What applications are ER Probes not suitable for?

لا يُنصح باستخدام مجسات الطوارئ use in sour service because conductive (iron sulphide) scales are likely to be deposited.

تجميع مسبار التآكل ER

Begin by attaching the plug assembly, identified by its white seal, to the probe. This seal fits between the plug and the base. Secure it by turning the counter-thread in the reverse direction and using a wrench to tighten it. Once done, insert this assembly into the base—usually welded to the pipeline—and secure it further. Cap it off with the protective cover.

For the second step, align the probe adapter’s notch with the probe’s key slot, join them together, and fasten the connection. Tighten the top nut to ensure the adapter remains stable during use.

Next, set up the wireless transmitter, taking care to avoid any explosion-proof areas. Join the two white connectors; a flashing green light will indicate a successful power connection before it turns off. Shield the transmitter with its protective cover and transport it to the required location. Upon arrival, discard the red cap from the transmitter’s plug and connect it to the adapter’s matching key position. Secure it with the connecting nut, tightened with a wrench.

To finalize the setup, lock everything in place with a screw. With this last step, your equipment is fully installed and ready to use.

استخدام مسجل البيانات المحمولة

Turn on the tablet PC and open the Bluetooth settings software. Watch as the driver software initiates and the device connects. Then, promptly minimize the settings window. Next, open the EMT software and adjust the settings to pair with the device. Click on the ‘device scanning’ option. Once the device connects successfully, click to stop the scanning process. Now, proceed to download the data. The software will present you with data from various periods, automatically generating a data curve. Click on the curve to examine the data in detail.

At the same time, take the opportunity to calculate the corrosion rate. To do this, select a data point to mark the start of the collection and another point to mark the end. Then, click on the ‘corrosion rate calculation’ button. A value will be displayed, and based on this value, you will determine the next step.

خاتمة

In conclusion, the مسبار EMT ER is a versatile instrument for monitoring metal corrosion, adaptable to various environments, but unsuitable for sour services. Its components and assembly process facilitate efficient setup and data collection, while the portable data logger simplifies onsite corrosion analysis. The model selection mode ensures the customization of the probe to specific pipeline requirements.
