Liquid sensor which thoroughly pursues simple model, simple system, 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 PKDLow 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 work-ability 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.
