Capacitive aluminum alloy car oil level sensor
CR-606 seriesCapacitive oil level transmitter (sensor), isRailway locomotive,Car fuel tank,Oil tank truck, the accurate measurement of oil level such as oil depot is tailoredSpecial instrument made, the whole machine has no movable or elastic parts, impact resistance, easy installation, high reliability, high precision, performance price benho. Can be installed in eachAccurate measurement and control of gasoline, diesel oil, hydraulic oil and other oil levels in various occasions, and also suitable for measurement of various non-conductive liquids. The site conditions are particularly harsh, electricityThis kind of product can also be used to measure conductive medium when magnetic interference is particularly serious and stirring is particularly severe.
The core components of the product adopt advanced RF capacitance detection circuit, which is converted into standard Telecom through accurate temperature compensation and linear correction through 16-bit single chip microcomputer.No. (generally 4-20 mA). HART,CANBUS and 485 communication protocols are optional for system configuration. Full seriesTransmitterAll have self-calibration function, and users canAutomatic calibration of "zero point" and "range" is carried out by button or lead wire to meet different requirements of various complex places.
Working Principle
CR-606 seriesCapacitive oil level transmitter (sensor)The sensing part of is a coaxial container, which causes the sensor shell and sensing electrode when oil enters the container.
The change of capacitance between, this change through the circuit conversion and accurate linear and temperature compensation, output 4-20mA standard signal supply display instrument.
