Overview
Characteristics
Operating Principle and Composition
■ Various kind of solid and powder levels can be detected.
■ Excellent performance for low or high density powder.
■ Long life cycle due to moveless parts.
■ No need to adjust sensitivity according to measuring material.
■ Available the Prevention function for Wave Chattering
■ Applicable to low density powder
HTM-930 Series is a Vibration Type Level Switch which detects a level of medium such as
solids or powder with simple structure. The device can be measured the solids of low density
(Styrofoam) and it is basically used for EPS (Expandable Polyethylene) Machine because it is
applicable to Styrofoam which has very low density.
The sensor is composed of one module consisting of oscillator coil an induction coil. When
the medium does not contacted with the sensing probe, the sensor is continuously vibrated by
oscillator coil. However, as soon as the medium touches the probe, vibration frequency and
output from the induction coil are significantly decreased, and relay output signal is activated
by the controller. It can be used for alarm and process control.
