The main technical parameters: Range (m) 0-1.5 ....... 50m output 4-20mA (1-5V); 0-10mA (0-5V); accuracy 0.5% linearity, repeatability, hysteresis (% F · S) 0.3% zero and sensitivity temperature drift (% / ℃ F · S) ≤0.03 zero drift (% / F · S4h) ≤0.3 long-term stability (% F · S / year) 0.3 operating voltage (V) + 24 Calibration (+ 18 ~ + 36) compensation temperature (℃) 0 ~ 70 Operating Temperature (℃) -20 ℃ ~ 250 overload (%) 300 life> 1 × 108 pressure cycles (25 ℃) Frequency (Hz)> 1000 Measuring medium hot liquids, corrosive liquid diaphragm material 316L stainless steel protection IP67 Housing material 1Cr18Ni9Ti interface split into MC20CD input type level transmitter (lead-pressure gas, used for high temperature, corrosive liquids, sewage, etc.) MC20CD input type level transmitter (lead-pressure gas, used for high temperature, corrosive liquids, sewage, etc.) of the sensor part of the signal processing circuit in the wiring inside the box, contact with the media by the gas within the gas cylinder liquid investments within By airway pressure delivered to the sensor, avoiding direct contact with the measured medium sensor, adapted to high temperature corrosive and other occasions, to effectively solve the high temperature corrosive liquid level measurement and sewage problems. It is particularly suitable for high temperature, corrosive liquids and measuring sewage. MC20CD level transmitter selection MC20B pressure transmitter for pressure measurement, fluid collected by the air collecting cylinder pressure signal, transmitted to the pressure transmitter, the pressure signal is converted to a signal level output. Pressure transmitter and level relationship: P = 0.0098ρH + Pc where: P pressure MPa; ρ liquid density (g / cm3); H surface depth (m); Pc surface pressure (atmospheric pressure 0) Main features: sensor does not contact the measured medium, high reliability and a unique conversion circuit, stable performance, overvoltage reverse polarity protection zero full-scale field adjustable
