Dust Monitor DT450G

Air pollution control systems such as bag filters and electrostatic precipitators are used to separate particulate or dust from the gas stream before it is exhausted into the atmosphere. To maintain the dust concentration of the emission gas below the specified level through effective operation of the control system, it is essential to continuously monitor the dust concentration of the exhaust gas.

Based on installation and application experiences with the old model DT400G, the microprocessor-based DT450G Dust Monitor features improved operationality and reliability. Features include one-touch automatic range setup in response to process conditions and automatic drift compensation. Also, the DT450G can measure at a process temperature of up to 250℃, allowing it to cover a wide range of applications.

Drift compensation
Direct measurement at a process temperature of up to 250℃
One-touch, automatic setup of range appropriate for the process conditions
Inductive electrificaion; probe is stain resistant and requires minimal maintenance
Integrated design allows for easy installation
Maintenance-free operation for a long period

Measurement range	0.1 mg/m3 to 1 kg/m3
Measurement principle	Inductive electrification
Sample gas conditions	Temperature :250℃ 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
Setting measurement range	Range setup: One-touch automatic setup or manual setup Note: With one-touch automatic setup function, measurement range is set so that the dust concentration 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: Variable (10 to 50%, 10% step)
Analog output signal	4 to 20 mA DC (isolated, load resistance of 500 Ω)
Contact output signal (high/low alarm)	2 outputs
Ambient conditions	Temperature: -20 to 45℃ Humidity: 95% RH or less (non-condensing) Vibration: 5 m/S2 (0.5G) or less
Construction	Integrated sensor and converter Direct insertion type, rainproof (IP64)
Materials	Sensor probe: Stainless steel (316SS equivalent) Insulation of sensor: PEEK Case: Aluminum
