Level switch : Level Sensors for Solids

Vibrating level sensor

Vibrating Level Sensor VC

Vibrating Level Sensor VC

Overview
Measurement is made using proprietary coil impedance detection. The sensor has a magnet and an electromagnet to which alternating current is applied. These two magnets cause the sensor to vibrate.
Automatic temperature correction ensures stable solid level measurement.
This compact sensor with a detector as short as 175mm is suitable for level measurement of small to medium size hoppers or pipe.
Features
Reliable measurement due to proprietary coil impedance detection.
Applications
Level measurement of pressure tanks of fine powders such as coffee powder, powdered milk, chocolate, and colcothar.
Typical solids and granular materials such as sugar, salt, wheat, flour and other grain, powdered cellulose, glass material, plastic pellet, powder or cement.

Vibrating Level Sensor VL

Vibrating Level Sensor VL

Overview
The sensor has a magnet and an electromagnet inside the detector. These magnets cause the detector to vibrate. The sensor measures change in current that flows on the electromagnet to know a level. Flameproof (TIIS Exd ⅡB T4) and intrinsically safe (TIIS ExiaⅡC T5) models are available.
Features
Measurement is made using proprietary coil impedance detection. 17 models including standard, remote, flameproof or intrinsically safe are available.
Applications
Level measurement of liquids, solids, granular materials and sludge blanket up to 150℃ (<180℃ with high temperature type)

High-Sensitive Vibrating Level Sensor VH

High-Sensitive Vibrating Level Sensor VH

Overview
The sensor has two piezoelectric crystals for oscillation and reception placed on a plate. The sensor detects decrease in board vibration to know solid presence.
Features
High accuracy solid level sensor using a vibration board supported at two locations. No moving parts and easy installation. A wide range of types available to suit specific applications.
Applications
Fine powders of bulk density > 0.02

Vibrating Level Sensor VM

Vibrating Level Sensor VM

Overview
Level measurement based on our original technology that uses a detector incorporating a piezoelectric crystal and an acceleration pickup. Compact and low cost. Solid level switch with the latest technology.
Features
No moving parts. Insensitive to dielectric constant, change in water content, or static electricity. No adjustment required. Fail-safe functionality. Integrated to any solid control equipment.
Applications
Small to medium size hoppers for solids equipment

Vibrating Level Sensor VP 11

Vibrating Level Sensor VP

Overview
The sensor uses a piezoelectric crystal to vibrate the plate, and the ringing is measured to detect solid presence. Compact and light weight sensor specialized for solid measurement.
Features
No moving parts, flat detector, adjustable sensitivity, easy installation and low cost. Ideal for integration into other equipment
Applications
Small hopper for solid control equipment

Vibrating Level Sensor VF

Vibrating Level Sensor VF

Overview
The sensor has a magnet and an electromagnet fixed on a plate. When current is applied to the electromagnet, repulsive force of the magnet causes the plate to vibrate.
Features
Robust and shock resistant flush-mounted sensor with a vibration plate as thick as 1mm. Remote type available.
Applications
Low limit detection of medium to large size hoppers



Motor torque level sensor

Reciprocating-puddle Level Sensor C5/B3 (Bin leveler)

Reciprocating-puddle Level Sensor C5/BC (Bin leveler)

Overview
The sensor converts motor rotation to reciprocating motion to activate the integrated microswitch.
Features
The best selling, simple and rugged model. A wide range of designs available. Operates flawlessly and offers long service life.
Applications
Solids, granular materials and bulk solids in small to large silos, in asphalt plants and batch plants

Rotating-puddle Level Sensor R7

Rotating-puddle Level Sensor R7
CE

Overview
Paddle inserted in the hopper rotates to detect solid presence.
Features
Easy torque adjustment, magnetic “slip” mechanism to protect the motor, very compact and lightweight, low cost and long service life
Applications
Integration into plastic processing machinery and cereal processing machinery

Rotating-puddle Level Sensor RB

Rotating-puddle Level Sensor RB

Overview
Typical rotating-puddle solid level switch that detects solids using rotating puddle
Features
Easy sensitivity adjustment, shaft if φ10mm to avoid affection from process conditions and to improve robustness.
Applications
Bulk solids (cement, flour, animal feed), granular materials (pellet, fertilizer, grain), and solids (coal, lime stone, ore)
