Combination Siphon and Level Sensor
- Multi-Level Switch Options
- Up to 4 Actuation Points
- Integral Siphon or Fill Tube
- Customized Mountings
Save valuable space and costly installation/maintenance time with
these highly customizable sensors. LS-350 units combine a siphon
tube and up to four liquid level sensors as a single component. The
complete unit installs through a single opening in the fluid container.
- Custom Configurable
Simple and clean — a single component that enables remote
monitoring of a tank’s fluid content while allowing access for
container filling and draining. These units are custom configured to
fit the container of your choice, with a wide range of mountings, fluid
and electrical connectors, materials and lengths.
• Automated Urine Analysis
• Laboratory Automation
The LS-350 Series provides two functions: liquid level monitoring and fluid fill or
extraction access. The latter function is accomplished with an integrated siphon
tube that runs parallel to the float sensor stem and through the top mounting; it
is commonly topped with a barb (or customer specified) fitting for the connection
of flexible tubing. Fluid level sensing is accomplished with magnetic reed switch
technology. One or more floats encircling a stationary stem are equipped with
powerful, permanent magnets. As a float rises or lowers with liquid level, the
magnetic field generated from within the float actuates a hermetically sealed magnetic
reed switch mounted inside the stem. The switch actuation may be used for alarm,
solenoid, pump or other fluid control operations.
1. Mounting Types
Each mounting type can be configured with stem lengths (LO) and as indicated below.
2. Float Types
3. Electrical Specifications
Typically, one float is required for each point at which you need a switch action to occur. The number of actuation levels available depends on the Group Type Wiring selected; see below.
Group I Wiring: 1 to 4 Actuation Levels.
Group II Wiring: 1 or 2 Actuation Levels.
Switch (SPST, N.O. or N.C.): 10/20/50/100 VA.
5. Electrical Connections
Type 1: Lead Wires, 24˝ to 26˝ (610 mm, Min.)
Type 2: Cable, 24˝ to 26˝ (610 mm, Min.)
6. Actuation Level Dimensions
Switch actuation levels are determined following the guidelines below.
