Fully-featured weighing indicators have OIML and CE approval

Complementing its current range of sensors for monitoring load, Variohm EuroSensor has added two new weighing indicators that offer OIML and CE approval, together with a host of features and options for commercial and industrial weighing applications. Ideal for both scale and process weighing tasks, the new 20i and 22i series can be configured with a choice of six-digit LCD or LED displays. Moreover, with an auto-switching AC supply or optional battery power for mobile equipment use, maximum durability is ensured with an IP67 rated stainless steel housing and mounting fixtures. A menu-driven user interface includes a membrane keypad with 12 numeric key, plus seven functional keys that enable straightforward selection of built-in weighing and counting modes where an Alibi memory retains the last 100k transactions. As standard, the units provide selectable digital I/O, four dry-relay outputs and two opto-isolated inputs for setpoints and batching. PC or PLC connectivity comprises an RS 485 full duplex interface or an optional Ethernet TCP/IP and USB 2.0 board can be specified. Two serial ports also offer printing, networking and other various serial streaming formats. A 20mA serial port is available for a remote display. The indictors will drive up to 10 x 350Ohm load cells (four to six wires) or up to 20 units of 700Ohm.
