Level measurement of bilge tanks and oil tanks

Miniature Float Sensor SH

Overview

Side-mounted level switch that measures a level using a float incorporating a magnet and a reed switch that operates because of a magnetic field.

Features

Easy installation on tank side using threaded process connection. Operational for any liquids of specific gravity >0.6. Switch operation easily reversed.

Applications

Integration into small mass produced equipment, level measurement of virtually any liquids due to corrosion resistant SCS14 (316SS equivalent)

Wide-Differential Float Sensor FS

Overview

The sensor detects liquid presence at a predetermined point using an integrated microswitch that operates as the float goes up or down with the liquid level. When detecting the liquid presence, the sensor gives an electric signal to trigger alarms or control solenoid valves and pumps. The sensor is ideal for level measurement of hydraulic units and boiler fuel tanks.

Features

One unit controls both high and low limits without an interlock circuit due to user adjustable upper and lower stoppers. Microswitch is capable of directly switching large loads such as solenoid valves. (250V, 5A AC/125V, 0.6A DC)

Applications

High/low control of hydraulic units or boiler fuel tanks

Float level sensor with cable

Cable Suspended Float Sensor FQ

Overview

Float of the sensor has a weight that goes up and down with the liquid surface, and a stationary magnet. When the weight approaches the magnet, the reed switch inside the weight closes its contacts to indicate a level.

Features

Latching relay offers control of both high and low limits by one unit. Insensitive to suspended solids. Stable operation and low cost.

Applications

Pump control of tanks and pits in water/wastewater facilities or effluent treatment facilities.

Cable Suspended Float Sensor FT

Overview

Cable suspended float switch that uses a microswitch to detect the level. The float tilts as the liquid surface rises or falls, causing a steel ball inside the float to roll and the microswitch to open or close its contacts.

Features

Microswitch is used. Corrosion resistant and offers long service life. Stable operation, easy installation. Suitable for a wide range of applications.

Applications

Pump control of tanks and pits in water/wastewater facilities and effluent treatment facilities

Guard Float Sensor FC

Overview

The sensor has a float fixed to the rope. The float has a magnet inside, and moves up and down with the liquid level, causing the reed switch inside the stem to open or close its contacts.

Features

Suitable for limited space, set points and switch operation are easy adjusted, easy maintenance

Applications

Water treatment facilities and applications with limited space above the tank

Pneumatic level sensor

Pneumatic Level Sensor FP

Overview

The detector of the sensor measures liquid head pressure and transmits it to the chamber. The diaphragm receives the pressure and actuates the microswitch. 
Flameproof model is available. (d2G4)

Features
