Capacitance level switches

LT/DS series
LT/DS series
These capacitance level sensors are backed by a long history of results and can measure any substance

Can be used to measure any material by using the variety of amplifiers and electrodes available, from super-high to low sensitivity.

  • For liquid
  • For powder

A variety of products is available to meet a wide range of customer requirements, including flange types, high temperature, heavy loads, wire types, corrosion proof, pipeline types, and intrinsically safe explosion proof types.

 

Features, keys

  1. A variety of product line-ups is provided to meet with a wide range of customers requirements
    A lot of amplifiers are available to match the material you want to measure. By providing amplifiers that match each application, our products offer even higher reliability.
    (Type LT-S2,LT-S2T,LT-S2Z,LT-S2OZ,LT-F2,LT-P2, etc.)
  2. The amplifier can be replaced easily, to make the amplifier unit system easy to maintain
    You can replace the amplifier without disconnecting the cables.
  3. It can handle materials stuck on the electrode and avoid the resultant malfunctions
    Eliminates problems caused by adhered material that had been a disadvantage of capacitance level switches.
  4. Explosion proof and non-explosion-proof types are also available
    Explosion proof type (DS) is also available for explosion proof sites. Separated-amplifier models are available for both explosion-proof and standard types.

Usages, use examples

The switches can detect liquids, viscous liquids, corrosive liquids, powders, granulated materials, foams, and interfaces

  • Almost all powders and granulated materials
  • Almost all liquids
  • Highly conductive and adhesive materials
  • Detects foam
  • Detects liquid while ignoring foam
  • Detects the interface between oil and water
 

Explosion proof type

DS power supply

The DS type switch consists of an electrode integrated into an amplifier case with a separate power supply. It is an intrinsically safe explosion proof design when the power supply is installed in a safe location. The electrode and power supply are connected each other using a 2-conductor shielded cable.

  • The electrodes are shared with the LT type.
  • Separated types, with separate electrodes and amplifiers, are also available.

The intrinsically safe explosion proof design means that any heat in a product cannot lead to an explosion, even if two breaches of safety occur. Furthermore, if any component in the equipment installed in a hazard area is shorted, it will not create a spark. This function has to be confirmed by an official institute using ignition tests and other criteria.

 

Amplifier separate type

This type is mainly used when the electrode position is subject to vibration.
(Type LT-S2EX / DS-S2EXj
Use a coaxial cable to connect the amplifier to the electrode (up to 5m).
