7430 SERIES INDUCTIVE RING SENSOR
INDUCTIVE RING SENSOR:
All 7430 Series flowmeters may be fitted with one inductive ring sensor.
The inductive ring sensor is mounted on the glass meter tube using
springs to put tension between the frame and glass meter tube.
The sensor can be either proximity or latching type and can only be
used with 316SS or Carboloy floats. The inductive ring sensor produces
an electromagnetic field that senses the metal float within sensing
zone.
Inductive ring sensors are 2-wire, DC, low current devices and are de-
signed to be used with a remote intrinsic safety barrier / switch isolator.
SWITCH ISOLATOR:
Inductive ring sensors are designed to be connected to a switch isolator
for intrinsically safe applications. The purpose of the switch isolator is
to supply electrical signals between safe and hazardous areas in either
direction while limiting the amount of energy that can be transferred
even under fault conditions. Switch isolators are available with 220VAC,
110VAC or 24VDC supply voltage requirements, contain single pole
double throw (SPDT) relays, and are DIN rail mountable. See switch
isolator specifications for electrical connections and further details.

INDUCTIVE RING SENSOR:
All 7430 Series flowmeters may be fitted with one fiber optic sensor.
FIBER OPTIC SENSOR:
The fiber optic sensor is mounted to the frame with a screw in a slotted screw
for adjustability. The sensor uses a pair of fiber optic cables with an emitter and
receiver to transmit the light generated by the sensor. The sensor can interface
directly to a Programmable Logic Controller (PLC) or when connected to a
separate relay can trigger a local or remote alarm.
