Product Type: Liquid Level

OLS2 Series Liquid-Level Sensor

The OLS2 series is a liquid-level sensor for single-point liquid-level detection. The sensor has an infrared emitter and detector aligned within an accurately shaped cone to give good optical coupling when the sensor is in the air. This coupling is greatly reduced when the sensor is immersed in liquid, as the infrared light escapes through the liquid rather than being reflected back to the detector.

The sensor has a transistor output, so can be configured by the user for particular applications. Output is via TTL-compatible push-pull output.

Features

  • Low-cost sensors for general liquid sensing
  • High-reliability optical sensing
  • External mount via M12x1 thread
  • Standard temperature range -25ºC to +80ºC Extended temperature range -40ºC to +125ºC
  • High and Low output versions

Applications

  • Professional kitchen equipment
  • Industrial dishwasher
  • Food and beverage
  • Water storage tanks
  • Oil and gas

OPB350 Series – Tube Liquid Sensor

The OPB350 series liquid sensor is designed to work with 1/16” [1.6mm] 1/8” [3.2mm], 3/16” [4.8 mm], and 1/4” [6.3 mm] outside diameter clear tubes. When output reference circuitry is added, multiple output states such as “fluid present,” “no fluid present,” and “no tube present” can be recognized.

Clear liquid present causes the phototransistor to sink the maximum current, while dark liquid present causes it to sink the minimum current. As bubbles pass through the tube, the signal will vary between the “liquid present” and “no liquid” states. If no tube is present, the phototransistor sinks current between the dark fluid and clear fluid states. The customer will have to identify the typical current values for each situation. The ratio between the different states allows acknowledgment of different conditions.

Features

  • Can identify if the liquid is present in clear tubes that have an outside diameter of 1/16” [1.6mm], 1/8″ [3.2mm], 3/16″ [4.8 mm], or 1/4″ [6.3 mm]
  • Opaque plastic housing enhances ambient light rejection
  • Printed circuit board mounting or 24” (610 mm) 26 AWG wires

Applications

  • Noncontact fluid sensing
  • IV fluid
  • Oils and other petroleum products
  • Colored fluids
  • Toner fluids
  • Water
