In the first part of this 6-blog series, we introduced Instantel’s white paper (Limitations of MEMS Accelerometers for Vibration Monitoring Systems) that presented research comparing current Micro-Electro-Mechanical Systems (MEMS) Accelerometers against traditional solenoid geophone sensors. The paper concluded that, when it comes to vibration monitoring for industrial, construction and blasting applications, data from MEMS Accelerometers can be erroneous due to the frequency and amplitude of the vibrations being recorded, and are particularly unreliable when measuring high frequency vibrations caused by explosives, heavy construction equipment, jackhammers, pile drivers and the like.   In...

Monitoring vibrations at construction, mining and blasting sites is crucial to prevent damage to property and structures, and to comply with local, state and federal regulations. When it comes to the equipment used to measure the vibrations created by these activities, users have several options from which to choose.  Micro-Electro-Mechanical Systems (MEMS) Accelerometers While traditional vibration monitoring devices utilize geophone sensors, we have come across some new, less experienced manufacturers who are touting Micro-Electro-Mechanical Systems (MEMS) accelerometers as the modern replacement for the geophones. Those who promote MEMS accelerometers for the construction and...

Load Sensing Demo Kit - Unboxing Today we're going to do an unboxing of a load sensing demo kit. So we'll start by unboxing our gateway, and this is the new 4G gateway. So pull the gateway out of the box here. The ethernet cable is pre-installed. Put that to the side there, and then let's go through everything else we've got in the box here. LSG6 4G Items: A USB-C to ethernet cable. This is for local connection from the gateway to your computer. We won't need that right...

Setting up an Ultra Powermate with a Solar Panel & an Aeroqual AQS Air Quality Sensor Today we are going to be setting up an Ultra Powermate with a solar panel and an Aeroqual AQS air quality sensor: So the first thing that we're going to do is going to make sure all of our circuit breakers are in the off, down, off position. So once those are all switched off, we're going to take our lead for the battery cable and we're going to hook up our battery. Always...

Pole Mount Bracket - Fiberglass Enclosure Today, we are going to show you how to put together the pole mount bracket for our fiberglass enclosure. We've got all the hardware laid out here. Pan Head Screws Take the pan head screws, drop them through the outside most holes, and you want to leave the slots and U-bolt holes on the bottom so they are accessible once you actually want to put this on the bracket. Then you're just going to tighten those up. And you want to use these nuts...

Putting Together a Double Solar Panel Mounting Bracket We’ve got the bracket parts and all of our hardware here, which I’ve put the lock washers and flat washers on all the bolts just to make the assembly easier. I’ve got our 200 watt panel already ready to go on a nice cardboard surface so I don’t scratch it up, and I’ve got a 150 watt panel over here. Now, in this case, we’re going to mount the 200 watt panel first because it is larger. We’re going to put the...
