The communication device inside uses walkie-talkies
Thread Content
The communication devices in the unit are walkie-talkies. Do you use walkie-talkies to communicate between the main operator and the assistant operator? What brand do you use, and how effective are they? We use Motorola GP328s; they worked pretty well at first, but the quality of those used in recent years has been much worse
It’s from one particular brand, and it seems that the design isn’t very practical – sometimes the clip fails to hold things in place, causing them to fall to the ground; I’ve already broken several of them. I haven’t seen it, but many refineries are equipped with riot-proof phones with two-way communication functionality; however, I’ve never used them and don’t know how effective they are~~
The walkie-talkie channel is broken; we’re using mobile phone calls now
Explosion-proof walkie-talkies are widely used in chemical processing plants, with many of them being Motorola brand. However, in recent years, as design standards have changed, many control rooms and cabinet rooms have been built with explosion-resistant structures, which has a significant impact on communication quality. To maintain good communication, the only solution is to use antennas for signal amplification； For this reason, many companies now use explosion-proof phones to address communication issues between the control center and the field; they are convenient and practical, making them a good choice. Additionally, the explosion-proof radio intercom system installed in the facility will also play a greater role!
We used Motorola before, and now we use Kenwood. When comparing the two, Motorola has a stronger signal and a greater effective range. The Kenwood one is a bit smaller.
The quality of genuine products from well-known brands is still unmatched, but there are many fake versions available; since companies win bids at low prices, it’s inevitable to end up buying a lot of counterfeit goods
I’ve been using the Moto GP328 for five or six years now. . N of them are broken. . . Everything is fine except for channel switching issues when going to places like the tall tower. The clip is tight enough and is usually clipped at the epaulette on the left chest. Fully charged, no stress at all for an entire shift. Including low-temperature weather in winter. . The only slight drawback is that it’s quite large in size. . .
Motorola couldn’t find the model; it’s manufactured in Malaysia
Using Moto is frustrating; many of them have been damaged. It’s time to introduce new domestic models so that Moto can become a thing of the past. Explosion-proof phone. Explosion-proof phone! A portable explosion-proof phone. Sometimes it’s really hard to understand: as long as explosion-proof phones do not interfere with the proper functioning of instruments, they can be used in highly dangerous environments such as those with hydrogen or acetylene. And since these phones are often carried around by people, are humans also explosion-proof?
I’m using a Motorola device, and the signal quality seems poor; it’s okay within 500 meters, but the signal becomes weaker at greater distances. It might be that the explosion-proof wall in the control room is causing serious obstruction

The explosion-proof intercom systems available on site are only useful for specific, defined tasks; they are generally installed on the ground or in locations where they are used frequently. However, they are not installed in ordinary pump rooms or equipment platforms； Carry out specific, quantitative tasks such as switching to backup pumps, operating manual valves to adjust settings, and determining the opening degree of control valves; only explosion-proof walkie-talkies can be used for these purposes. Additionally, when instrument technicians need to check pressures and pressure differences at the top of the tower, relying solely on a walkie-talkie system is ineffective – no matter how loudly they shout. Today’s walkie-talkies are all digital, with greatly improved sensitivity; as a result, they are more likely to be jammed. They are also consumable devices that operate 24/7, so no machine can be considered highly durable. Some leaders are too bureaucratic; they reject any proposals related to energy conservation and cost reduction, so nothing is available for such purposes. As a result, losses become inevitable.
