M3 and M3is family of wireless ultrasonic level sensors from Vydas
Sensing and instrumentation specialists Vydas International Marketing have released the new Massa M3 and M3is wireless ultrasonic level sensors for tank level and precision distance measurement.
Manufactured by Massa Products Corp., the M3 Zigbee-enabled ultrasonic sensor design provides low-cost, non-contact ultrasonic distance measurement primarily for remote tank liquid level monitoring. The M3 wireless ultrasonic sensor is also available with intrinsically safe certification for Class 1 Division 1 (All Groups) Hazardous Locations.
Applications for this sensor include: liquid level control, mechanical positioning, roll diameter measurement, web loop/break monitoring, asset tracking, remote monitoring, automatic filling operation, automatic packaging, bulk level control, paper and plastic film processing and many others.
Reliable and affordable, the M3 wireless ultrasonic sensor transmits narrow-beam sound pulses, processes return echoes and produces several outputs. The measurement output is then transmitted by low-power Zigbee radio to a ‘gateway’ and the information is presented to the user via LAN, cellular or web portal.
Operating on internal batteries with a typical lifespan of three to five years, the M3 family of sensors has a detection range of 4in to 30ft. The distance measurement is transmitted via Digi International Xbee radios and gateway.
The M3 sensor contains advanced on-board diagnostics as well as many user-adjustable output settings, including: measurement sampling rate; radio transmission rate; averaging of multiple distance measurements; as well as reporting battery voltage, temperature and other parameters.
The network also allows users to remotely program their sensors and read ranges for quick integration into their remote monitoring application. Other features of the M3 ultrasonic sensor include: chemically resistant Kynar housing with 2in NPS fitting for mounting, built-in temperature compensation, and diagnostic and monitoring outputs.
