Low-Cost Solid-State Rain Detector

Hydreon Corporation (Minneapolis, MN) has released the new RG-9 low cost, low power, rugged, and reliable precipitation sensor. It uses beams of infrared light to detect rainfall. Consequently, the sensor is impervious to dirt, dust, insects, birds, and the other nuisances that can plague sensors. Since it consumes very little power, it is well suited to solar-powered applications.

The RG-9 readily senses drops smaller than a millimeter and its threshold can be adjusted to trigger at whatever intensity of rainfall the application requires. The device features a serial output, so trip thresholds may be adjusted as needed by the user's equipment.

The most common type of rain sensor is conductive. This is simple but prone to being left in an “always on” state if the surface becomes contaminated. Also, conductive rain sensors can generally not sense small amounts of water, and the threshold is generally not adjustable.

Wireless System for Acquiring Precision Measurement Data

The L.S. Starret Co. (Athol, MA) has announced the introduction of DataSure® 4.0, an advanced wireless system for acquiring precision measurement data. It uses short-wave radio frequencies to interconnect cell phones, computers, and wireless electronic devices, enabling much faster speed, greater bandwidth, and a range of hundreds of yards.

Features include higher bit rates and less than 50ms of data travel time. Its ultra-low latency network enables high data volumes to be processed without delay, even at full capacity. Multiple gateways serve as central or distributed points for data collection. The compact new gateways and repeaters can easily fit in the palm of a hand.

Built on a highly secure proprietary wireless platform, transported data is encrypted using a multi-layered approach that prevents any outside access to the data, whether passive or active. Data is transmitted from gages that have either built-in radio transmitters or externally-mounted end nodes to gateways.

Energy Harvesting Wireless Power

The VP3 energy harvesting power source from Xidas, Inc. (Irvine, CA) captures energy from small vibrations in industrial machinery (motors, blowers, pumps, etc.) and converts it into electrical power that trickle charges a specialized on-board battery. This enables wireless sensors to have access to a perpetual power source that eliminates the cost and headache of battery replacement and maintenance.

Wireless sensors have unique power signatures that put a strain on regular batteries. With the increase in intelligent sensing, sensors can now capture and analyze signatures, monitor for alarms and environment, be network aware, and transmit to customers’ networks. All these wireless devices must balance what the edge device does with how much power capacity the battery can provide. Unfortunately, most wireless sensors typically have a 1 to 2-year lifetime, leading to costly and bothersome battery replacements/maintenance that deem many IoT applications impractical.

Thermal Mass Flowmeters

Endress+Hauser (Greenwood, IN) has launched a line of Proline t-mass F/I 300/500 flowmeters. These thermal mass flowmeters are reliable and versatile for measuring pure gases and gas mixtures. Each has numerous alarm functions, as well as bidirectional measurement capability, and reverse flow detection.

In many industries, thermal flow measuring technology has been used for measuring pure gases and gas mixtures. For example, in research and development labs, measuring flare stack and flue gases, in utilities with compressed air, oxygen, nitrogen, or argon, etc. As a result, when combined with features such as WLAN, and configurable I/O, this opens possibilities for process control, quantity measurement, leak detection, cost allocation, energy management, and other applications.

Even when process and ambient conditions significantly fluctuate, t-mass ensures high measurement accuracy (±1.0%) with excellent repeatability (±0.25%). Gas flows with low pressure and a low flow velocity can also be measured easily thanks to a high turndown ratio. It can operate at process temperatures up to 356°F and pressures up to 580 psi.

Digital Temperature Sensors

The new STS32 temperature sensor from Sensirion AG (Stafa, Switzerland) comes with an ISO 17025-accredited, three-point calibration certificate. The calibration data and the sensor specifications are compliant with good distribution practices (GDPs) for pharmaceutical and medical logistics. When medical or pharmaceutical products are shipped, minute temperature monitoring has to be maintained to guarantee both product and patient safety. With the analog temperature sensors commonly used in the past, the whole measurement chain had to be calibrated, which limited calibration scalability and cost optimization. Digital sensors incorporating the complete measurement chain on a chip, however, allow precalibrated temperature sensors to be used in data loggers, eliminating the need for the manufacturer to perform additional calibration procedures.

The STS32 is a digital, I2C-based temperature sensor. Its calibration set-points are T = -30°C, 5°C, and 70°C. All the values are provided in a machine-readable CSV file format and can be associated with the sensor in question by using the sensor’s unique, unalterable serial number.

Clamp-on Ultrasonic Flow Meters

AW-Lake (Oak Creek, WI) introduces a new series of Clamp-On Ultrasonic Flow Meters that fasten on the outside of vertical or horizontal pipes ranging in size from ½" through 48". Housed in a water- and dust-tight NEMA 4X polycarbonate enclosure, the meters are compatible with a range of metal and plastic pipe materials and “difficult liquids” such as chemicals, viscous liquids, and abrasives that would damage standard flow meters. As a result, the non-intrusive, clamp-on ultrasonic sensors feature enhanced flow measurement with no pressure drop in a range of applications such as food or chemical processing plants, oil refineries, and more.

Operating from 100 – 240 VAC, the clamp-on ultrasonic flow meters offer an isolated 4-20 mA signal output. Programmable relays are useable for flow control, pump protection, or flow proportional pulse. A built-in keypad and simple menu system simplify calibration and programming of pipe diameter, pipe material, liquid types, and measurement units.

High-Accuracy Inclinometer with Machine-Learning Core

The IIS2ICLX from STMicroelectronics Geneva, Switzerland) is a high-accuracy, low-power, 2-axis digital inclinometer for use in applications such as industrial automation and structural-health monitoring. It features a programmable machine-learning core and 16 independent programmable finite state machines that help edge devices save power and reduce data transfers to the cloud.

Using MEMS accelerometer technology, the IIS2ICLX inclinometer has a selectable full scale of ±0.5/±1/±2/±3g and provides outputs over an I2C or SPI digital interface.

Non-Contact Industrial Pyrometer

The new thermoMETER CTRatio pyrometer from Micro-Epsilon (Raleigh, NC) provides accurate results with non-contact temperature measurements in harsh industrial environments. Unlike conventional pyrometers, it delivers constant measurement results even when surrounded by dust, smoke, and vapors, as well as with contaminated lenses, or when the object is moving within the measuring field.

It is based on the ratio measuring principle, which enables reliable measurements in harsh metal processing environments. Even if only 5% of the measurement object is within the measurement spot, the CTRatio provides reliable measurement results. Due to the high spectral sensitivity in the range from 1.45 to 1.75 m, measurements are possible from +250 °C. New calibration methods extend the temperature measuring range to +3000 °C. With a response time of just 1 ms, even high-speed processes can be monitored reliably.

A green sighting laser that works at a wavelength of 520 nm helps alignment of the pyrometer and offers significantly better visibility on red-hot glowing, metallic surfaces.
