1.2 Specifications
Measurement objects: Solid particles in gas
Particle size : 0.3 µm or greater
Measurement range: 0.1 mg/m
3
to 1 kg/m
3
Measurement principle: Inductive Electrification
Process conditions :
Temperature : 250ºC or less
Pressure : 200 kPa or less
Gas flow rate : 4 m/s or greater (approx. 30 m/s max)
Humidity : 40%RH or less
Input surge voltage : 100 V or less (if 500 V or greater, converter may be damaged.)
Note : When installing downstream of ESP, see Item 2.1.
Measurement range:
Range setup : One-touch automatic setup or manual setup (Measurement
range does not directly represent dust concentration.To know the
absolute value of dust concentration, the relationship between
the output signal and the dust concentration should be obtained
by laboratory analysis or relevant way.)
Note : With one-touch automatic setup function, measurement range is set so that the dust concentra tion of the process
corresponds to a setpoint of setting level. In manual setup, the measurement range is set by gain (x1, x10, x100,
x1000, x10000).
Setup range level : Variable (10 to 50%, 10% step)
Analog output signal : 4-20 mA DC, insulated, load resistance; 500 V
Contact output signal (high/low alarm):
Contact capacity : 5 A, 240 V AC or 24 V DC
Setting range : 1 to 99% (1% step) of measurement span
Contact type: NO (closed when alarm contact is activated) or NC, 2 outputs
Note : Relay is energized when alarm contact is activated.
Damping time constant : 10 to 300 seconds, 10 second step
Relay output time constant : 10 to 180 seconds, 10 second step
Ambient conditions:
Temperature : -20 to 45ºC
Humidity : 95%RH or less (non-condensing)
Vibration : 5 m/s2 (0.5 G) or less
Construction:
Converter : Integrated with detector, protection rating IP 64
Sensor probe : Direct insertion
