Press Release Summary:
DetectorÂ® Micropower Impulse Radar Sensors consist of Series MIR-800 with solid waveguide rods, and Series MIR-900 featuring fully encapsulated, flexible rods. Units measure distance to surface of tank contents and output 4-20 mA signal proportional to liquid level. Sensors pulse microwaves every 2 Âµsec and capture fresh readings every 310 msec. Resolution and repeatability are 0.01 in. with response time less than 2 sec.
Original Press Release:
ALL-NEW Radar Liquid Level Sensing Now Made Affordable from Gems Sensors
PLAINVILLE, CT-Gems Sensors Inc. introduces the all-new Detector® line of Micropower Impulse Radar (MIR) liquid level sensors that promise a new level of affordability for OEMs and process users alike. Gems Detector® MIR sensors, the most affordable radar liquid level sensors ever brought to market, are now available in two series: MIR-800 Series sensors feature solid waveguide rods, while the MIR-900 Series sensors feature fully encapsulated, flexible rods. Each series offers specific advantages. Detector® sensors are effective for measuring any liquid with a dielectric equal or greater than 3.0 and are particularly effective in media that often frustrate other measuring technologies. Foaming liquids, viscous and coating fluids, slurries and other particulated liquid media-all are candidates for the Micropower Impulse Radar technology employed in Detector® sensors.
Detector® sensors use Micropower Impulse Radar (MIR), or Time Domain Reflectometry (TDR), to measure the distance to the surface of the tank contents and output a 4-20 mA signal proportional to liquid level. Detector sensors pulse microwaves every 2 µsec and capture fresh readings every 310 milliseconds. Resolution and repeatability are 0.01" with a response time less than 2 seconds.
MIR-800 sensors feature solid waveguides to reach within <1mm of a tank bottom; especially beneficial when controlling expensive fluids, where undetected inventory beneath common sensors represents costly waste. A deadband of just 1/4-inch is located at the top end just below the mounting. These sensors are stocked and available with rods of 24" or 72" and are trimmed to required length during installation. For OEM customers, Gems supplies finished units sized per specification and ready for
MIR-900 Series sensors are longer, handling tank depths to 12 feet, and feature a flexible dual rod waveguide that is completely encapsulated with Tefzel®. This low-dielectric material resists buildup and provides a bridge between the rods that facilitates accurate wave reflection, even when they become
coated. Two standard lengths are available, which may be trimmed to size to fit tanks 12 feet deep or less. A stainless steel weight, fitted at the guide's end, maintains guide rigidity. The OEM version is sized and calibrated at the factory and supplied with a fitted RytonS end weight. With zero deadband at the top, MIR-900 sensors are capable of measuring tank contents right up to the bottom of its mounting.
