Overview
Characteristics
Operation
Principle and
Appearance
A certain level of electric signal is transferred to the piezo sensor so as to vibrate the
tuning fork. The vibration of the latter is reduced when it comes in contact with the
subject. As such, the electric signal is reduced to stop the oscillation of the piezo sensor.
The electric signal is detected by the electronic circuit to operate the relay, so that the
state can be detected with the contact output.
■
Level of different powder types can be detected.
■
It can measure powder particles, ranging from small to large.
■ The membrane is made of stainless steel with a solid structure and a high bearing capacity.
■
The wiring is simple.
■
It is customizing with the key button.
■
It has a simple structure for easy maintenance.
■
It has Ex-proof and Dust-proof structures. (HPV-Series)
The HTM-20N Series is a tuning fork type vibration level switch that consists of one
membrane and two stainless forks to detect powder and output the state using the
relay contact, which is applicable for alert and process control.
