一.Level Switches and Level Sensors:

S&W designs level switches and level sensors including single and multiple point level switches,

continuous level switches and more. These level switches are available in both standard and engineered application needs. The wide selection of materials offers reliable and durable level sensors for all liquid environments, as well as full range of other application conditions. S&W designs level switches can incorporate the temperature sensors into level sensor, offering combination sensing and cost savings for many applications.

三. Level Switches and Level Sensors Application:

1. Apply in level control of household applications, such as Water dispenser; Air-condition; and Vehicles’ Oil Level control, etc…

2. Apply in Industrial Automation System to control the oil, water, Hydrochloric acid, sulfuric acid and other corrosive solution.

四. PP or Stainless Steel Continuous Level Transducers:

S&W PP or Stainless Steel Continuous Level Transducers are designed for vertical and side mounting In a tank. Reed switched are evenly spaced over the operation range to achieve the desired resolution. A single magnet-containing float travels the length of the sensing range. The reed switches are magnetically actuated as the float moves with the liquid level. DC power is applied to the switch, and the output signal can then be routed to programmable controllers, PP or Stainless Steel Continuous Level Transducers Feature:

1. Stem material of PP,SUS304 and SUS316 are available with either a stainless steel, polypropylene or Buna-N float. PP stem length can be up to 40’’, SUS304 and SUS316 stem can be up to 100’’.

2. Flexibility for varied fluid environments

3. Suitable for any tank application

4. Provides precise, uninterrupted readout with 5mm;10mm or 15mm resolution

5. Various output signals available (4-20Ma,1-5DC,resistive,etc..)

五．PP or Stainless Steel Continuous Level Transducers Application:

1. Remote sensing in tanks with restricted or limited access

2. Precise liquid level monitoring in series of tanks in mixing operations

3. Central monitoring of liquid level in remote multiple tanks

4. Any tank application where the exact liquid level has to be know at any time

六.PP or Stainless Steel Multiple Level Switches

S&W offers a complete line of Standard and Configured (slightly modified Standard designs) models to meet the needs of applications in many markets, at competitive prices. In addition, S&W offers the capability to design specific PP or Stainless Steel Multiple Level Switches for OEM application that require unique considerations in materials, configurations and system interfacing to reduce the cost.
