2284 Ultrasonic Gap Switch



  • No moving parts
  • Compact sensor
  • Corrosion resistant

2284 Ultrasonic Gap Switch

The Ultrasonic gap switch consists of Polyphenylene Sulphide (PPS) and is high corrision resistant in most liquids. The 2284 Ultrasonic Gap Switch is designed for high or low level alarm in different tank applications as well as pump control. However, if there is a liquid present, the signal will be transmitted across the gap and the integral electronics will switch the output circuitry to signal the presence of a liquid.

It can be mounted in any position in a tank using a 3/4″ or 1″ thread available in BSP and NPT thread forms.

Features of the 2284 Ultrasonic Gap Switch include:

  • No moving parts
  • Self contained full plastic body
  • Compact sensor for narrow spaces
  • Small in-tank dimensions
  • 1″ and 3/4″ threaded mounting
  • Corrosion resistant PPS body
  • Relay output

General Applications:

  • Pump control
  • Demineralized water
  • Chemicals
  • Water/Glycol solutions
  • Cooling water
