The Samsara HM11, machine health monitor, magnetically mounts to a machine case, which allows for the continuous tracking of key health parameters for pumps, fans, motors, and compressors. The HM11 records 0.5 seconds of X,Y & Z accelerometer vibration data every 5 minutes, while simultaneously recording temperature every 4 seconds. The included sensors monitor vibration in mm/s or ips with a frequency range of of 10Hz to 1 kHz and a measurement range of +/- 16g. The sampling rate for vibration monitoring is 1666 Hz with an accuracy of +/- 10%. The surface temperature monitoring with the included sensors have a range of -40 to 85 degrees C with an accuracy of +/- 1 degree C.
The data is sent through Bluetooth to a Samsara IGX1 base and then uploaded to the cloud via the integrated cell modem. Once the data is in the cloud, Samsara calculates the RMS velocity in each direction as well as an FFT spectrum between about 10 and 1000 Hz.
Below is an example of the overall RMS velocity level data for X,Y & Z. You can see it uses the ISO 10816 recommended levels for warning and shutdown. The alarm levels are designated by light red and yellow corridors.
Below is an example of the FFT spectrum output, this example shows the plots provided for the Y direction of the HM11 sensor. There are two plots generated from the FFT output, with a standard display of the amplitude vs. frequency for the most recent data sample on top and a colored (blue to red) amplitude history of the top plot right below. Data goes back in time moving down, and the timeframe is the same as the timeframe that was selected in the velocity RMS plot above.
The interface is simple and user friendly. Contact Neal Systems HERE to request a demonstration.

Neal Systems Engineer Peter Jackson has created a simple but effective solution using a Red Lion Cellular Data Modem. In this application note, Peter demonstrates a simple, but powerful feature of the event engine and how to control the level of water in a fish tank.
The same principle can be used for a municipal tank level, flow, pressure, temperature, or to a stirrer.

Industrial biogas is a byproduct of several processes within a variety of industries. If your process includes biogas as a byproduct, then the accurate and consistent measurement of the biogas’ makeup is essential in maximizing its commercial value and ensuring safe and compliant operations of your plant and process.
The Four Main Components: Methane, Oxygen, Hydrogen Sulfide, and Carbon Dioxide
Methane Measurements: Methane (CH4) being the primary component, the measurement of its composition and quality is essential in maximizing the benefits from private and government-backed incentives for this biogas to be used as a fuel source.
Oxygen Measurements: Accurate and reliable measurements of oxygen (O2) is critical in maintaining the appropriate levels of saturation to prevent the generation of explosive mixtures of methane (CH4) and oxygen (O2). These measurements also ensure efficient levels of microbial activity to eliminate the potential for oxygen to poison an anaerobic digestion process.
Hydrogen Sulfide Measurements: The corrosive, flammable and poisonous nature of hydrogen sulfide make it necessary to ensure that the hydrogen sulfide (H2S) level is maintained at level of ideally less than 200ppm, minimizing the potential for corrosion when the condensing gas forms sulfuric acid.
Carbon Dioxide Measurements: Carbon Dioxide (CO2) is used as an effective indicator of efficiency of an anaerobic digester performance. Understanding the performance of the digester is instrumental in keeping your product and plant protected.

The winter months bring low temperatures, which leads to the risk of pipes freezing and bursting. A burst pipe can cause a catastrophic failure in some plants. Recently, a Neal Systems engineered solution mitigated this risk and allowed for preemptive action to be taken to avoid a shutdown and costly repairs.
The image shown, shows the temperature inside an enclosure containing controls for the liquid flowing in-to and out of a large tank. At 06:40 AM the tank temperature hit a low of 16 degrees Fahrenheit. This monitoring allowed for our customer to take action immediately to avoid a costly shutdown and repair.
Our solution consisted of a Eurotherm 2500/VersaDac I/O which collected the data from the piping system via 4 to 20 mA signals from temperature, tank and flow levels using a Foxboro IDP10S and a Foxboro RTT15S.
The data was transmitted using a Red Lion Cellular Data Modem in a PLC and a Eurotherm 6180A Recorder. Eurotherm’s Review software produced the image shown, which was being remotely monitored by the customer.
Neal Systems expertise in designing and supplying cost effective solutions, saved our customer tens of thousands of dollars in repairing freeze damage to pipes.
