TENSION LINK DYNAMOMETER

This dynamometer load cell is suitable for tension applications such as winching, hanging crane scale, and lifting systems. Openings at either end of the crane load cell allow for easy connection to shackles, wire rope, or other rigging. These hanging scales are available in capacities ranging from 10,000 pounds to over 250,000 pounds. Custom dynamometer capacity, size and safety factor is also available upon request. Each tension load cell is teperature compensated and completely environmentall sealed.

All Tension Links

	WIRELESS TENSION LINK DYNAMOMETER Tension load is displayed via external indicator that communicates wirelessly with the tension link. Wireless crane scales have a transmitter and battery box attached to the load cell to communicate with the indicator (see wireless digital indicator). The scale is powered by 4 AA batteries with a life of 200+ hours of continuous use. The tension meter enters sleep mode when not in use to prolong battery life and has wireless range of 40 meters line of sight.
	WIRED LINK (HARD CONNECT) Tension measurement can be displayed by an indicator via wired connection (see wired digital indicator) . The cable connection between the crane load cell and display can be a seal-over hard connect. This is suitable for installations where the dynamometer is not expected to be disconnected from the indicator. Standard cable length is 40' but custom cable lengths are available.
	WIRED LINK (MILITARY CONNECT) External indicators can also be connected to the tension load cell via 4-pin military style quick-disconnect. This allows for easy disconnection and reconnection from the load cell should the crane scale ever need to be moved, repaired, or stored. The drawback of military connectors is that their sealing standard is not as high as hard-wired connections. Quick Disconnect cable comes in 10', 20', and 50' lengths.
	M2000 LOAD CELL INDICATOR The recommended indicator for tension applications is the M2000. If the crane is located outside, the M2000 should be purchased in a NEMA enclosure (see left photo) to protect against dust and water. Various enclosures are available (see below images) and more details about the M2000 are available in the product guide (see right).
	SETPOINT OPTION CARD The M2000 is available with a setpoint option card. These are overload detection and protection devices. Setpoints utilize solid state relays that can be used to trigger alarms or switch devices (i.e. motors) on or off at specified weights. When ordering the Setpoint optoin the type of device (AC or DC) being switched must be specified. Setpoints are frequently used in digital hanging crane scale applications
	PARTS OF LINE SOFTWARE The M2000 can be loaded with a special program that allows a hanging crane scale operator to adjust the indicator for multiple "Parts of Line". The program is configurable for one to twelve parts of line and the software will be provided free of charge when needed with the purchase of an M2000 indicator and a crane scale dynamometer.
	REMOTE SCORE BOARD Remote score boards are often referred to as "remote displays". This type of display must be used in conjunction with a digital indicator equipped with a serial output. The remote display mirrors what is displayed on the weight indicator. They are used in applications where weighing information needs to be seen at a distance from the indicator. Score boards are available in 2" (50 foot visibility), 4.5" (250 foot visibility) and 6.5" (300+ foot visibility) lettering.
	4-20 mA SIGNAL CONVERTER We can supply 4-20 mA ouput versus standard mv/V signal. The design incorporates a load cell shield connection and polarity insensitive current loop connections. It is not susceptible to damage from shorting loop leads together or to ground during operation and is specifically designed for ESD hazardous envornments. These converters are usually used in systems that use a PLC.
