Microwave Flow Switch

Description

Microwave FlowSwitch, applying the principle of Doppler Effect, is a flow detection sensor for bulk solid/powder applicable to various application like flow monitoring of pneumatic feeding line, plugged chute detecton, etc. High performance in flow and plugged detection for dry powder. Hardly influenced by adhesion or dust because of high permeability microwave system. Self-diagnosis function automatically detecting decrease of sensitivity. Digital circuit system preventing set value from drifting. Withstanding pressure ability up to -980MPa+980MPa internal- pressure in pipe.

FEATURES
Hardly influensced by adhesion or dust because of microwave system
Self-diagnosis function automatically detecting functional depression
Withstanding pressure ability up to 980kPa internal-pressure in pipe
The operational indication can be checked at a view without opening cover
Free voltage (AC90-230V) strong against power fluctuation and disturbance noise
Easily detachable without disconnecting

Description

This is space-serving type motion sensor which consistsof a transducer to be mounted in the panel and a separated proximity switch to be mounted at the place where detection is conducted. It is possible to conduct speed control in the control room apart from the place where detection is conducted and to conduct collectively a integrated control by mounting side by side transducers from each place where detection is conducted.

FEATURES

With the built-in digital switch, the actuating speed is adjustable at site
Not affected by vibrations of machines, since the distance between the sensor and the sensing piece is allowed up to 18mm
Simple control circuit, as the starting compensation timer is built in
Free power source does not cause a mistake in connection to 100V or 200V
Compact, light weight and high performance series
IP67 protection allows the use in bad environment
Aluminium housing and strong against corrosion

APPLICATIONS

Detection of shaft speed of machinery

Microwave Barrier Switch

Description

Microwave Barrier Switch detects the upper and lower limits of silo, hopper, etc.The microwave system enables non-contact detection and easy maintenance. Further the mounting positions can be easily decided because detection works when the accumulation of material blocks the straight line between transmitter and receiver. Max.detection distance 100m realized. Small detection area dia.25mm of transmitter/receiver enables easy installation. Free voltage model from AC80 to AC240V reliable against unexpected voltage variation and disturbance noise.Exact and stable sensitivity setting can be made easily. Self-diagnosis function automatically detects decrease of sensitivity due to adhesion etc.
