Checkweighers Specifications

Help with Checkweighers specifications:

Type

	Type
	Your choices are...
	In-Motion Checkweigher		In-motion checkweighers are used to verify that the weight of a product is within prescribed limits. These process scales weigh parts while in-motion and usually have a conveyor belt.
	Check Weighing Scale		Check weighing scales are also used to verify that the weight of a product is within prescribed limits; however, unlike in-motion checkweighers, they do not have a conveyor belt. Instead, the product must be manually loaded and unloaded.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Capacity

	Capacity		Capacity is the maximum load the scale or balance can measure without permanently damaging the device.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Resolution		Resolution refers to the smallest input or change in input that the device is able to detect.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Maximum Throughput		Maximum throughput is the maximum rate, measured in parts per minute, than an in-motion checkweigher can measure.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

Platform

	Width / Diameter		For round platforms, this is the width or diameter of the weighing platform, tray or pan.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Length		This is the length of the weighing platform, tray, or pan.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Display / Interface

	Display
	Your choices are...
	None		The device does not have an integral display.
	Analog Display		The device has an analog display such as a needle.
	Digital Display		The scale has a digital display. Examples include liquid crystal displays (LCD), light-emitting diodes (LED), and vacuum fluorescent displays (VFD).
	Other		Other, unlisted displays.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
	Remote Display		The device has a remote display that is not part of the scale or balance itself.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Interface
	Your choices are...
	Ethernet		Ethernet is a local-area network (LAN) protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976. It uses a bus or star topology and supports data transfer rates of 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards.
	Parallel		Outputs are transmitted via standard digital protocols that carry more than one bit simultaneously. General-purpose interface bus (GPIB) is a common parallel interface.
	Serial		Outputs are transmitted via standard serial protocols that carry data one bit at a time. RS232, RS422, and RS485 are common serial interfaces.
	USB		Universal serial bus (USB) is the standard serial bus for low-to-medium speed peripheral device connections to personal computers (PC) and peripherals such as keyboards, mice, modems, printers, joysticks, audio functions, and monitor controls.
	Wireless		Wireless systems consist of combined radio frequency (RF) components such as transmitters, receivers, transceivers, filters, down / up converters, antennas, and antenna positioners. Wireless systems use low-powered radio waves to communicate data between these devices without the use of cables.
	Other Interface		Other, unlisted interfaces.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features / Certifications

	Rejector		The scale has a mechanism for rejecting parts that are out of the specification range.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
	Ratings / Certifications
	Your choices are...
	IP66		The scale is IP66 rated. The first digit (6) indicates that the scale is sealed against dust. The second digit (6) indicates that the scale is protected against pressurized jets of water.
	IP67		The scale is IP67 rated. The first digit (6) indicates that the scale is sealed against dust. The second digit (7) indicates that the scale is protected against immersion at depths between 15 cm and 1 m.
	NEMA 4		Scales with a NEMA 4 rating are designed for indoor or outdoor use. An enclosure protects personnel against incidental contact with the scale, and protects the scale from falling dirt, rain, sleet, snow, windblown dust, splashing water and hose-directed water. NEMA 4 scales are undamaged by the external formation of ice. They are not necessarily corrosion resistant.
	NEMA 4X		Scales with a NEMA 4X rating are designed for indoor or outdoor use. An enclosure protects personnel against incidental contact with the scale, and protects the scale from falling dirt, rain, sleet, snow, windblown dust, splashing water and hose-directed water. NEMA 4X scales are undamaged by the external formation of ice. They are also corrosion resistant.
	NTEP Certified		The scale is certified by the National Type Evaluation Program (NTEP). The National Conference on Weights and Measures (NCWM) issues an NTEP Certificate of Conformance for scales that have been successfully evaluated and tested.
	WEEE Compliant		Waste Electrical and Electronics Equipment (WEEE) is a European Union (EU) directive that is designed to encourage the reuse, recycling and recovery of electrical and electronic equipment. WEEE establishes criteria and requirements for the collection, treatment, recycling and recovery of this equipment. It also makes producers responsible for financing these activities. For their part, retailers and distributors must provide a way for consumers to return used or obsolete equipment without charge. WEEE became effective on August 1, 2005.
	Other		Other, unlisted rating or certifications.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
