Alarm Options:

Inductive Ring Sensor
Inductive ring sensors are designed to be used with a remote intrinsic safety barrier/switch isolator. These sensors are able to detect the metal float by producing an electromagnetic field within the ring. Ring sensors are available in either proximity or latching format for the 7400 Series.

Sensor Specifications
Power Supply: 5-25 VDC (from Switch Isolator)
Max Current, Target Present: 1 mA
Max Current, Target Absent: 15 mA
Operating Temperature Limits: 0°C to +40°C (1/8 Inch Float)
Operating Temperature Limits: 0°C to +70°C (1/4 Inch Float)
Output: NAMUR
Repeatability: 0.01 mm
Switching Frequency: 2 kHz (.125”),
1.5 kHz (.25”)

Sensor Approvals:
UL Listed: General Purpose
FM Approved: Intrinsically Safe*
CSA Certified: Intrinsically Safe*
Cenelec: Intrinsically Safe*

Fiber Optic Sensor
The fiber optic sensor is housed in a junction box attached to the side of a 7400 Series flowmeter. The sensor uses a pair of fiber optic cables, an emitter and receiver to transmit the light across the metering tube and back to the sensor. If the light beam is blocked by the float, the sensor output will change. The sensor provides a transistor output that switches the common or negative voltage (NPN) or positive voltage (PNP) to the load. The fiber optic sensor is compatible with all 7400 Series float types

Sensor Specifications
Supply Voltage: 10-30 Vdc
Current Consumption: 25 mA
Temperature Limits: -14°F to +212°F
Output:
NPN (Sinking), N.O. or N.C.
PNP (Sourcing), N.O. or N.C.
Offstate Leakage Current =1 microamp at 30 Vdc
Output Saturation Voltage = 1 V at 10 mA DC < 1.5 V at 150 mA DC

Note: Sapphire floats are not compatible with Fiber Optic Sensor
