PK series

Liquid sensor which thoroughly pursues simple and low cost.

The diaphragm at the center of flange detects liquid pressure proportional to the liquid level.
The semiconductor pressure transducer converts liquid pressure into current signal, and output 4 to 20mA DC.

Features of Model PK

• Low cost by simplified performance and function
  Output signal: 4 to 20mA DC (Two wire system)
• Flat face avoid residual liquid.
• Achieve weight saving by using plastic flange material
  No need a jig of sensor support for installing to FRP tank
• Wide variety of flange material to suite medium
  Plastic flange for waste water or chemical tank, etc.: PP / PVC / CPVC
  Metal flange for purified water, etc.: 304SS / 316SS
• No need Teflon film sheet due to the plastic flange of high corrosive resistance
• Possible to cut down the total cost
  No need a jig of sensor support and Teflon film sheet
  Improvement of workability at site
• Possible to measure without adjustment and setting
  Possible to set a measuring range before shipment
  (Measuring range: 0 to 4m / 0 to 10m)
