ELECTRODYNAMIC DUST MONITOR VIEW370/VIEW370 PLUS/LeakAlert/VIEW Ex800/DS30c
Compared with general friction charge methods and the conventional optical detection method, this dust monitor has a high resolution and stability without being easily affected by adhesion of dust to the probe.
- It is rarely affected by adhesion and contamination on the probe.
- Extremely high sensitivity of 0.01 to 1000 mg/m3.
- High-humidity gases can be measured by special air purge. (VIEW370/VIEW370 PLUS)
- Support for 16-channel sensor (VIEW370 PLUS)
- It can be connected with our different models using a common path. (VIEW370 PLUS)
Operating Princicles
The charge transfer of fine particles such as dust flowing across a pipe or airflue is applied to static induction and detected by the noncontact sensor. This signal is measured and converted into an alternating-current response. The friction current produced when particles directly hit the probe is cut and this realizes stable output through the special circuit.

Features
FORWARD SCATTERING DUST MONITOR QAL181
This monitor can make stable detections regardless of the presence or absence and types of dust chambers and exhaust gas treatment systems including a large boiler and large kiln.
- The pin spot measurement minimizes the influence of various conditions.
- High resolution: 0.1 mg/m3 Recommended measuring range: 0 to 10/100 mg/m3
- A zero span self-diagnosing function is provided.
- A 16-channel sensor is supported by the multi-controller (optional).
Operating Princicles
Laser light is irradiated on dust particles, and the scattered light (forward light scattering method) is collected and scattered by the mirror, and then detected through the quartz rod.
As forward-scattered light from which the largest scattering intensity can be obtained is collected with an efficient collection mirror and detected through the quartz rod without transmission loss, the monitor can make stable detections with less influence of noise.
