Comprehensively equipped weighing indicators.

Complementing its existing range of sensors for monitoring load, Variohm EuroSensor has added two new weighing indicators 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 & 22i series can be configured with a choice of 6-digit LCD or LED displays. And, 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 20 mA serial port is available for a remote display. The indictors will drive up to 10 x 350 Ω load cells (4 to 6 wires) or up to 20 units of 700 Ω.

The many application configuration possibilities for the 20i and 22i include but are not limited to the following: Custom ticket printing with gross, net and setpoint in a customisable format that can include print time and date, unit ID, and consecutive ticket number; Accumulation where weights are totalled with an armed print function; Batching with up to eight batch steps with latched or continuous outputs for gross, net and delay setpoint. Actions include trip high or low, wait for standstill, print, accumulate and tare; Keyed tare—pre-set tare value can be entered when the gross weight is at zero; Configuration for local/remote where the remote unit displays weight and transmits key press commands to the local unit; User and operator password protection; Audit trail tracking; Time and date.
