Truck Scale Intercom System
Truck scale intercom systems come in wired or wireless and this video discusses the benefits of each.

How to Choose a Truck Scale Intercom System

We’ve been selling truck scale intercoms for many years but finding the right solutions has been challenging. We used to have antiquated wired system from the 1970’s that was loud at the scale but it had no noise cancellation so scale house operators couldn’t understand the truck drivers well. Then we found a wired system that had noise cancellation but it wasn’t that loud so the drivers couldn’t hear.
The same goes for a wireless system. We found a product that had excellent noise cancellation but not enough volume at the scale. Fortunately, we were able to work with the manufacturer to develop a solution that now has both volume and noise cancellation. We also now have a strong solution for a wired system as well.

Another frequent problem we had is where clients needed an intercom on both ends of a bi-directional scale, or they had multiple scales.

With our current wireless solution there isn’t a way to select which intercom you talk to so the only way to address those situations is with multiple base station intercoms inside. Not ideal, but possible in situations where you just can't run wire.

With our latest CAT5 wired system one telephone on the inside can easily handle multiple scale callbox intercoms outside. If you need more than one scale operator inside it can accommodate that as well.

We’ve got lots of experience with truck scales so it you need help configuring a system, please call 888-298-9489 and we will help you get set up. You'll save yourself some time and money by not trying to make the cheap solutions out there work which will give you all the same problems we experienced over the years. Those Chinese-made products lead to unhappy clients or results. If a business uses a scale to make money, trying to cut corners is not a good business decision.

Wireless Truck Scale Intercom

Truck weight scales come in two major varieties: wired and wireless. Regardless of the type you choose, the system needs to be loud and it needs noise cancellation. Our most popular option is the Full-Duplex Wireless Truck Scale Intercom with Amplified Horn Speaker.

Quite often they are surrounded by concrete and there is no way to trench through concrete to lay a wire. Or there may have been a conduit with wire but it got damaged along the way.

The full-duplex wireless has an amplified horn speaker that mounts above a stainless steel box that houses the electronics and the microphone. Full duplex mean that both parties can speak at the same time, just like a telephone call. You can set up an optical sensor that is triggered when the truck pulls up so it calls the scale house intercom and then the scale operator can pick up the call so the driver never has to press a button. Alternatively there is an auto-answer software upgrade that lets the scale house operator press the button on the inside unit and the outside unit will automatically answer without the driver having to press the button.

Wireless Intercom for Multiple or Bi-Directional Scales

The problem with the above wireless system is when you have multiple scales or you have a scale the is bi-directional. If you have multiple scales you can add additional outdoor callboxes and have them on the same channel. If you have multiple trucks coming in at the same time, then you can only talk to one of them.

For lane that is used bidirectionally where trucks come in and out on the same scale, you need a callbox on each side/end of the scale. You can use the optical sensor because both callboxes will be triggered and you will end up talking to the wrong end of the truck. You can't use the optional auto-answer feature because both callboxes will answer and you'll get feedback thereby rendering the audio quality to be poor or useless. You can solve these issues by installing completely separate systems for each lane or each side of the scale. There are 9 channels on the wireless intercom so you could theoretically have up to 9 separate systems but this would take up a lot of desk space for the inside intercoms.

Multi-Lane Wired Truck Scale Intercom

If you can run Cat 5 or 6 cable to the scale or scales, then the High-Definition Audio Wired Truck Scale Intercom Kit is a great solution. You can connect optical sensors to it so the driver does not have to call, or the scale operator can call the scale intercom directly so the driver does not have to press a button.

Wired Truck Scale IntercomThis is a Voice Over IP system that uses a desktop phone on the inside to communicate with as many outside scale callboxes as needed. You could also have multiple inside phones which would be beneficial for busy scales where multiple scale operators are needed.

With this system you can easily put a callbox on each side of a bi-directional scale however an optical sensor would still not work since both will be triggered. You could use a sensor to ring a bell or alert device to notify the scale operator, and then the scale operator could call the appropriate scale callbox.

Another benefit of this system is the inside phone has a handset you can pickup for privacy, it has hands-free speakerphone capability, or it can use headsets so it is extremely flexible for the scale operator.

If all you need is a system where you just make announcements to drivers and you don't need to hear them, a simple wireless PA system such as discussed in the video below will suffice:
