Easy migration to 2D code reading
A brand new range of 2D code reading products will provide an inexpensive solution for businesses to migrate from the existing less robust 1D barcode methods
When employed by one of Hawk's clients, the Microwave Pulse Switch was able to save nearly $50K per year that was previously being spent on manufacturer on-site testing and compliance certification.
This particular client had turned to Hawk because it wanted to replace existing nuclear-based point level switches used for plugged chute detection on its coal handling transfer conveying system for a coal fired power station with an alternate technology.
Upon the installation of Hawk's Microwave Pulse Switch in the client's facilities, expenditures were immediately cut.

Compact bar code reader offers versatile mounting
For its versatile, high speed reading or decoding of linear and 2D codes on flat work and cartons within a depth of field of 50mm, the new AV1200 from Accu-Sort may be unmatched.
With energy emissions below FCC CFR Section 15 limits, there were no longer caution signs posting requirements or hazards associated with the equipment operation, which can be installed and maintained without specialised training or licensing.
Hawk's system has been running for approximately five years in this client's facilities and has led an initiative within the utility to replace all nuclear based instruments with safe alternatives where applicable.
Offering low-cost installation and cabling as well as switch-fail relay, the Microwave Pulse yields accurate and comprehensive results.
Other key features include water-tight, dust-tight and chemically resistant NEMA 4X enclosures, no required site-licensing.
The Microwave Pulse Switch is ideal for applications in which microwave energy is absorbed by the monitored material, including replacement of traditional contact switching devices used in mining, sand and gravel quarries, cement plants, pulp paper, plastic, rubber, coal-fired power plants, steel mills, aluminum smelters, food, pharmaceuticals and other manufacturing fields.
It is used for a variety of applications, such as flow/no flow, plugged chute detection, low and high level measurement, product-on-conveyor detection, rail/truck load-out position detection, anti-collision crane detection, blocked feeder pipes, water bottom detection and replacement of tilt switches.
The Microwave Pulse Switch is a high power unit with 300ft maximum and maximum flexibility for down to 8-inch minimum.
The Remote Microwave Pulse System is comprised of three units: a sender unit, a receiver units and an amplifier unit.
The Integral System is comprised of two units: the send and the receiver units.
The Sender-Receiver units are mounted facing each other and are mounted securely and correctly aligned.
