Variohm EuroSensor has added two new weighing indicators to its existing range of sensors for monitoring load, that offer OIML and CE approval plus a host of features and options for commercial and industrial weighing applications. Suiting both scale and process weighing tasks, the new 20i and 22i series can be configured with a choice of 6-digit LCD or LED displays.
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 keys + 7 functional keys that allow straightforward selection of built-in weighing and counting modes where an Alibi memory retains the last 100k transactions.
As standard, the units offer selectable digital I/O, four dry-relay outputs and two opto-isolated inputs for setpoints and batching. PC or PLC connectivity includes an RS 485 full duplex interface or an optional Ethernet TCP/IP and USB 2.0 board can be specified. Two serial ports also provide printing, networking and other various serial streaming formats. A 20mA serial port is available for a remote display. The indictors will drive up to 10x350Ω load cells (4 to 6 wires) or up to 20 units of 700Ω.
The many application configuration possibilities for the 20i and 22i include but are not limited to the following:
