Overview
The ZM303 is a durable, high-performance indicator with a numeric keypad and a range of built-in weighing applications such as general weighing, counting accumulation, filling, batching, and checkweighing, helping streamline business processes.
The ZM303 offers multi-connectivity, with Ethernet, RS232 and a USB Host port as standard options and analog output, USB device, Current Loop, RS485/RS422 and wireless as additional connections. This weight indicator comes in four versions:
ZM303 Aluminium IP20 Enclosure with IBN display – ideal for office type environments.
ZM303 IP69K Stainless Steel Enclosure with IBN display – offers complete protection against water and dust ingress, along with resistance to high pressure cleaning, making it ideal for use in indoor, dusty/wet environments or food processing areas where high pressure cleaning is essential.
ZM303 IP69K Stainless Steel Enclosure with TN LCD display – offers complete protection against water and dust ingress. Its TN display ensures clear visibility indoors and outdoors. With its resistance to high-pressure cleaning, this version makes it suitable for food processing applications.
ZM303 IP66 Panel Mounted model with IBN display – offers high resistance to dust and water, designed specifically for simple installation in control panels or control room applications.
Each ZM303 Weight Indicator features:
The ZM303 Weight Indicator features two highly visible weight displays that can be viewed from a distance, both in low and brightly lit environments. The IBN display version is a high-contrast, 0.8” (20 mm) high-digit display featuring green digits on a black background. This view provides excellent color contrast and enhanced viewing angles, reducing operator error and improving productivity, ideal for indoor applications. The TN LCD display uses the same high 0.8” (20 mm) digits but the colors are reversed, showing black digits on a green background. When used in direct sunlight, the black digits become more visible, making it a great option for outdoor applications.
Designed to ensure compatibility and communication between old and new peripheral technologies, the ZM303 has multiple serial ports, a USB port and an Ethernet socket that can be configured to support a number of independent devices, both DHCP client/server. The ZM303 is designed to monitor and capture key weight data in the background. It is able to connect to PCs, PLCs, printers, scanners, relays and remote displays, making it perfect for controlling and monitoring each step of the process.
Simple to operate while remaining fully flexible to print and record a wide range of weight data. The ZM303 offers predefined print formats that can be modified to meet printing requirements.
This 10,000d legal for trade approved, single base indicator provides outstanding weighing accuracy, perfect for any business that trades by weight. It is designed to connect up to most bench scales, floor scales or hoppers with up to 6 x 350ohm load cells. Approved for use in a wide range of global regions (NTEP /Measurement Canada, UK/EC/OIML).
The ZM303 can hold one option card internally to provide more flexibility to the indicator to work within a required process. The options cards that can be used are:
