Technical Performance
Application Object: Thick liquids, directly measured high-temperature gases or vapors, chemical corrosive media, liquids prone to crystallization.
Measurement Range: Refer to the selection specification table
Output Signal: 4-20mA dc. output, with HART protocol digital signal (two-wire system)
Power Supply: External power supply 24V dc., power supply range 12V - 45V
Installation in Hazardous Areas: Flameproof type dIICT6; Explosion-proof type iaIICT6; Technical indicators
(under non-migration, 316 stainless steel diaphragm and other standard test conditions.)
Accuracy: ±0.1%, ±0.075%
Application and selection:
When the measured medium is led out through a pressure guiding tube, it is prone to solidification or crystallization;
If the measured medium contains solid suspended matter or is too viscous, it is likely to clog the pressure guiding tube;
If the temperature of the measured medium is too high or it is corrosive, direct measurement is not feasible;
The measured medium is food or other media that require maintaining hygiene conditions and cannot be contaminated;
