The LIQUI-FLOW series L10I/L20I digital Liquid Flow Meters / Controllers for low flow ranges are equipped with a rugged 'industrial style' (IP65) pc-board housing for use in industrial environments. The instruments operate on a thermal, thru-flow measuring principle.
The LGR-5320 Series are high-speed, stand-alone data loggers for analog and digital signals. Each module offers 16 analog inputs, 16 industrial digital inputs (up to 30 V), one single Form C relay (0.5 A) digital output for triggering/alarming, and four counter/encoder inputs. All inputs are sampled synchronously.
1-stage preset counter, 1-stage preset counter with total counter (selectable). Power supply circuit and input circuits are isolated inside the Counter/ Tachometer. Previous non-isolated counters had wiring restrictions and could be damaged if wired incorrectly. The H7CX removes these worries.
