Avery Weigh-Tronix’s new range of ZM series weighing indicators are the first in the scale industry to use the highly visible display screen technology to make operation simpler and more accurate.
IBN technology provides high contrast and enhanced viewing angles to draw the eye to the screen, even in poor lighting conditions, to help reduce operator error. One of the indicator models, the ZM303 series, also offers a TN LCD display that has dark digits against a green, backlit lighter background to reduce operator fatigue.
For harsh operating environments or for heavy washdown environments, such as in the food industry, the indicators can be supplied in an IP69K rated stainless steel enclosure. These enclosures feature Gore-vent technology, a membrane that allows the indicator to ‘breath’ without sacrificing its IP69K rating. This overcomes the problem of trapped moisture inside the indicator, which is caused by the expansion and contraction of gases due to temperature changes. Other enclosures include a protective aluminium option or a stainless steel panel mount version for control room applications.
Says Don Halbert, product manager for Avery Weigh-Tronix:
“We have designed these indicators to meet the practical needs of industry. They are robust and durable but also help to solve a common issue of poor visibility leading to operator error.”
The ZM series is available in two models, ZM301 and ZM303, and eight variants.
ZM301 is a simple, basic weight-reading indicator. It has six operational keys including zero, print, units, tare, select and F1. Built in operational routines and applications enable users to configure the device for their own needs.
The addition of a numeric keypad allows ZM303 users to store multiple TAREs and numeric IDs in its internal memory for easy retrieval. Keys for counting, checkweighing and process control operations are also standard.
The new indicators capture weight data at a rate of 80 times per second and have multiple standard connectivity interfaces that include Ethernet, two RS232 serial interface ports and USB ports. Analog output, USB device, current loop, RS485/RS422 and wireless connectivity are also available as options.
