IP68 Submersible Pressure Transducer For Measure Liquid Level With Display

  Production Introduction:QST-202 liquid level transmitters are consisting of well-sealed immerging oil-filled liquid level transducers and special circuit for manometers. Have characteristics of high precision, good stability, long life and easy to fix. Adopt special sealed configuration, so with good capability of anti-leakage.According the relation between pressure, density and liquid level, the liquid level transducers measure the liquid pressure which in direct ratio with depth of liquid, then via amplificatory circuit, the measured pressure is transferred to standard 4~20mA current signal(or standard voltage signal).           Feature: ◆Wide measurement range◆Sealed structure: IP68.◆Various output signal◆CE Certificate  ◆Marking : ExiaIICT6◆Integrated construction, LED display can be choosing. Dimensions: (unit: mm)  Technical Specifications: Measuring mediaLiquid which are compatible to 316L   stainless steelMeasuring rangemH2O0~0.6,0~1,0~2,0~5,0~10,0~20,0~30,0~50,0~100,0~150,0~200Overload pressure%FS150Signal outputtransmitter, mA (2 wires)4~20mAtransmitter, Vdc (3 wires)0~5V, 1~5V, 0~10V, 0~20mAPower supplyVdc12~36（Standard 24Vdc）Static accuracy %FS±0.1,  ±0.25(Standard)Zero adjustment%FS≤±0.25Span adjustment%FS≤±0.25Long-term stability<±0.1%FS/year (＞20mH2O   )   ±10mm ( ≤20mH2O )Response timems<2Storage temp.ºC-40~+100Operation temp.ºC-20~+80Compensated temp.ºC-10~+60Temp. coefficient of ZERO%FS/10ºC≤0.2Temp. coefficient of SPAN%FS/10ºC≤0.2Insulation resistanceM Ω≥500 @ 100 VdcLoad resistancecurrent output, Ohm250~1100voltage output, Ohm>5000Environmental protectionIP ratingIP 68pressure memberane material 316L Stainless steelElectrical connector materialCast aluminumMaterial for housingStainless steel（1Cr18Ni9Ti）Electrical connectionconnector/cable4-core,Ф7.6 mm   shielded cable with vent pipe which is mechanically strong enough for deep   submersible liquid level measurements  Electrical connection:
