The TU 7050 is a two channel switching transmitter for use with turbine flow sensors. Pulse signals from flow sensors operate a dual set of galvanically insulated, dry contacts which in turn, may be used to activate alarms. Set point adjustments are allowed, in up to 16 increments, via a pair of rotary switches set into the module’s front panel. The rear panel contains the DIN rail mounting assembly. Two selectable modes are available:
Two identical turbine flow sensors operate one set point each.
One turbine flow sensor operates a pair of alarm set points (pre-alarm & main-alarm or min. & max.).
The TU 7050 provides a failsafe mechanism as any malfunction of the flow sensor would immediately trigger the low flow alarm setting. The set points are very easily adjusted via the very visible, rotary dial settings and additional oversight is offered by 2 LED lights. The red LED will light in a no-flow condition and a green LED indicates flow.
