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.

For Installation
Installation
■Check the level and presence of liquid in the tank before removing it.
■The product may be overheated so wear gloves to prevent burns.
■Before removing, please make sure that the power should be disconnected.
■Flange and Screw of the product should be same with nozzle connector for the installation.
■In order to prevent a loosening, washer should be used between the bolt and nut.
■Gasket should be used between flanges. (Gasket should be selected considering of
temperature of medium and pressure of the tank)
■The Power should be connected after completed installation and wiring.
■Below recommendation should be considered when installation.
■It is recommend to clean and check the sensing rod frequently by removing the sensing
rod from the vessel when the material is hard or high viscous.
Make sure the any damage while handling and transportation is not
allowed because it may cause of malfunction.

■Precautions for Using
- When installation to the tank, it should be proceeded using adequative tools
- Avoid any impact to the product
■Precautions for Wiring
- When wiring, cables should be wired to terminal correctly as per required wiring
method (Refer to Wiring)
■Disposal of the product
- When the product is discarded, dispose it after separation of the AMP in the housing,
and main sensor.
* There is no part influencing over environment, user does not require to pay attention.
■Product Identification Mark
Name Plate is attached on the Housing, describing the Model of product, serial
number, operating temperature, operating pressure and output signal. The Serial
number is a unique manufacturing number for the identification of product.
Temperature of the medium in the tank should not exceed max. 250deg.C. And
also, ambient temperature around housing should not be over -20Deg.C ~
+60Deg.C.
■If it is detected the medium but there is no change of output signal.
■If it is not detected the medium and there is no vibrating of sensor.
