Product Details Supplier Info More products

Magnetrol’s Echotel Model 962 level switch is not sensitive to build-up, aeration, foam and turbulence as it relies on pulsed ultrasound wave technology to monitor transducers.

The unit features two setpoints on the same transducer, which enables it to be used for low- and high-level alarm, high- and high/high-level alarm, low- and low/low-level alarm, or for pump control in an auto fill/empty mode.

There is also an adjustable time delay of up to 45 seconds and an output signal test button.

Additionally, the level switch does not require calibration as it is not sensitive to changes in density or liquids.

Key information

  • Response time of less than 0.5 seconds.
  • LEDs indicate operation and malfunction conditions.
  • Can be used with nearly every type of liquid, up to a maximum viscosity of 10,000cP, depending on the transducer.
  • Functions within a temperature range of -80–165°C.
  • Operates within a pressure range from vacuum up to 130 bar.
  • The unit is offered loop-powered with a mA output.
  • It is also available AC/DC line-powered with integrated relays.
  • Designed for use in ATEX, as well as explosion proof areas.
  • Conforms to the Pressure Equipment Directive.
  • Can be integrated into SIL 1, 2 or 3 loops.
