Remote wireless monitoring is only as good as the performance of the monitoring device. Period. Often the performance of the monitor comes down to the power source. This is a key piece of a fully functioning monitoring device – especially if the equipment is in a remote location like an oil or gas well or is a mobile asset like transportable tanks and rail cars. For example, suppose your monitor gathers every last measurement but cuts out, requires a new set of batteries every month, or runs on electricity. In that case, you’ll spend more time monitoring your monitor’s power levels than any other critical thresholds affecting production. 

One primary purpose of the monitor is to reduce the amount of onsite time spent manually recording the equipment’s performance levels. So, if a remote monitoring device requires a lot of maintenance, including switching out batteries, the cost-to-benefit ratio quickly decreases. 

Batteries that are easy to get

The Sentry Technologies Watchdog ST monitoring devices run on simple, everyday long-lasting batteries. Because you don’t have to worry about replacing batteries more than once every few years, you can focus on monitoring to ensure equipment is functioning correctly. 

Specifically, the Watchdog ST utilizes a SmartOneC transmitter that uses 4 AAA lithium batteries, while the input board requires one 3.6-volt C battery. 

Installation that is easy to do

Not only do these devices use everyday batteries to ensure critical equipment is up and running, but the battery installation is no more than what you’d expect from your alarm clock or portable radio (if your phone hasn’t replaced those yet). All you need is a flat head or Phillips screwdriver. 


But if you don’t want to change your batteries or install it yourself, just give us a call. We’ll come out and get you all set. 

Keep It Simple. Keep It Sentry.

Simple batteries and installation are another way to deliver on our motto, “Keep It Simple. Keep It Sentry.” We know what it’s like being out in the field. We were drilling some of the first wells in the Eagle Ford of South Texas. Things get complicated, but monitoring critical equipment shouldn’t be. Being confidently in the know at all times is priceless.

If you are responsible for monitoring any type of critical equipment, including mobile assets in the oil and gas industry, agricultural industry, or even rural or municipal water supply, the Sentry line of remote monitoring devices provides an economical and reliable way to keep an eye on everything.
