Works with hydrostatic level sensor measuring principle: When the measured liquid level transmitter into the head of a deep level sensors, liquid level sensors meet the pressure on formula: Ρ = ρ.gH + Po Where: P: pressure on the liquid level transmitters meet ρ: Measuring liquid density g: the local acceleration of gravity Po: atmospheric pressure on the surface H: pressure transmitter into the depth of the liquid at the same time, through the air conductivity of the liquid steel Positive pressure is introduced into the cavity of the sensor, is connected to the negative pressure chamber and the atmospheric pressure Po on the surface of the sensor and then to offset Po on the back of the sensor, the sensor measured pressure: ρ.gH, obviously, by taking the measured pressure P, You can get the level depth. Level Sensor Features: ◆ stability level sensor, full-scale, long-term stability of zero up to 0.1% FS / year. The compensated temperature range of 0 ~ 70 ℃, the temperature drift of less than 0.1% FS Differential pressure sensor in the entire operating temperature range of less than 0.3% FS. ◆ reverse protection, current limiting protection circuit, the installation will not damage the positive and negative reversed transmitter, an exception will automatically limit transmitter within the 35MA. ◆ solid-state structure, no moving parts, high reliability and long service life. ◆ easy to install, simple structure, economical and durable. Level sensor main technical parameters: Technology: diffused silicon ceramic capacitor capacitance sapphire optional. Split optional integrated liquid level sensor, range: 0 --- 0.5 --- 200 m, output: 4 --- 20mA (2-wire) Power: 7.5 --- 36VDC recommended 24VDCCBM-2100 / CBM-2700 submersible hydrostatic level gauge and reliable corrosion probe with ceramic measuring cell for level measurement of water purification, sewage and salt water. GY500 into split level transmitter diffused silicon piezoresistive core body, 316 stainless steel structure, the use of isolation explosion-proof housing design, the input level meter is mainly applied to rivers, groundwater level, reservoirs, water towers and containers, etc. level measurement and control. Signal isolation amplifier circuit, the cutoff frequency interference design (anti-jamming ability, lightning) overvoltage protection, current limiting protection, impact, corrosion and other designs. ] The main technical parameters: b] Measuring media: oil, water, fluid pressure type: gauge pressure, absolute pressure (no requirement default gauge)] Range: 0 ~ 300m midscale optional Overall accuracy: 0.1% FS Output signal: 4 ~ 20mA (two-wire), 0 ~ 5V, 1 ~ 5V, 0 ~ 10V (three-wire) Supply voltage: 12 ~ 36VDC medium temperature: -30 ~ 60 ℃ ambient temperature: -40 ~ 85 ℃ zero temperature drift: ≤ ± 0.05 % FS ℃ range temperature drift: ≤ ± 0.05% FS ℃ compensation temperature: 0 ~ 70 ℃ Safe overload: 150% FS Ultimate overload: 200% FS Sampling frequency: ≤2ms :( current-carrying capacity) 250 ~ 1425Ω (voltage type ) ≥2KΩ sealing rating: IP68 long-term stability: 0.1% FS / year first level sensor, level sensor, one hundred to one hundred technology provided by Changzhou Technology Limited.
