Level sensor of intrinsically safe explosion-proof type of preparing a plurality of amplifier. Easy amplifier exchange.

Maintenance is easy amplifier unit system explosion-proof capacitive level sensor

  • Provides a rich amplifier, corresponds to the variety of the object to be measured.
  • Intrinsically safe explosion-proof counterparts.

And maintenance is an easy amplifier unit system, replacement of the amplifier is easy.

  • Intrinsically Safe gets 3aG4.

Flange type, high-temperature, heavy duty type, wire type, corrosion-type pipe-line type, such as offers a rich product lineup that can respond to the diverse needs.

1. explosion-proof type is
DS type is composed of two points and the power supply unit electrode portion with an integrated amplifier unit, is intrinsically safe explosion-proof structure to install a power supply unit with a safety retaining element in a safe place.
Between the electrode portion and the power supply unit is connected by a 2-core shielded cable.

2. maintenance is to be replaced in an easy-amplifier unit system easily
can also easily replacement of the amplifier when the broken amplifier.

3. to malfunction due to the adhesion and adhesion of liquid corresponding
have to eliminate the worry of malfunction due to the attachment is an electrostatic capacitance type of disadvantages.

4. We also available amplifier separation type.
You may want to use if you are mainly vibration to the electrode portion attachment point.
Between the amplifier section and the electrode part is connected by a coaxial cable (up to 5m).
