HIC series smart valve positioner contains several kinds of specifications such as HIC11, HIC12, HIC08.It uses two-wire system transmission (The power source 4í½20mA simulating signal simultaneously transmits on two lines ). The psitioner and the actuator constitute a close loop control circuit. In this control circuit, the valve position feedback single as an variable which compared with rated signal in microprocessor and the D-value between them sends out different length of pulse through the delivery outlet of the main control panel to control the output pressure of the I/P change unit, thereby the positioner drive the control valve to act. (Refer to Fig.1) The pneumatic control valve with HIC smart valve positioner can overcome the friction force and unbalanced force of the valve plug well and enhance reaction speed of the control valve to rapid and precision localization, especially for vibration frequent places. It can replace conventional explosion-proof current-to-pneumatic valve positioner. The purchaser can monitor the valve position information through the feedback current and regulate or set the controlling parameter of the positioner with axial magnet or upper monitor at any moment. The purchasers only need to reset the relative parameter of the valve positioner and avoid changing the control valve because of the control system variation, so it is widely used in automatic control system such as petroleum, chemical industrial, electric power, metallurgy and light industrial, etc. TECHNICAL PARAMETER í± Input signalú¦4í½20mA analog signals í± Input loading voltageú¦7Víó9Vú¿With communicationú¬ í± Air supply pressureú¦0.16MPaí½0.6MPa í± intrinsic errorú¦í+1.0% í± Hysteresisú¦1.0% í± Dead bandú¦0.1%ú¿Min.ú¬ í± Functionú¦Self-diagnostics, configuration, travel characteristic correction, HART communication and so on í± Air consumptionú¦í_4.0Nl/min í± Strokeú¦10í½100mmú¿Turn angle 60ípí½90ípú¬ í± Conditions of working atmosphereú¦ a.Ambient temperatureú¦-40í½+80ípCú¼Explosion ¿Cproof typeú¦-40í½+60ípC b.Ambient humidityú¦5%í½95%ú+ c.Ambient atmosphereú¦86í½106kPaú+ d.There is no corrosive gas in ambient air. í± Power supplyú¦24V.DC í± Explosive-proof signú¦Ex dIICT6íóEx iaIICT6 í± Explosive-proof gradeú¦Factory Explosive-proof í± Enclosure classificationú¦IP65.

Short Description: The magneto-strictive level gauge is mainly used for continuous measurement of liquid level and liquid interface. Applications include: petroleum, chemical raw material storage, industrial processes, biochemistry, pharmaceuticals, food and beverage, tank management and gas station underground inventory, liquid level industrial metering and control, ship (dock), dam water level, reservoir water level monitoring and sewage treatment. The structural part of the magneto-strictive liquid level sensor is composed of a stainless steel tube (measuring probe), a magnetostrictive wire (waveguide wire), a movable float (with a permanent magnet inside), and a precision detecting circuit. When the sensor is operating, the circuit portion will excite a pulsed current on the waveguide wire that will generate a pulsed electromagnetic field around the waveguide wire as it propagates along the waveguide wire. A float is arranged outside the sensor probe, and the float can move up and down along the probe as the liquid level changes. There is a set of permanent magnetic rings inside the float. When the pulsed current magnetic field meets the magnetic ring magnetic field generated by the float, the magnetic field around the float changes so that the waveguide wire made of magnetostrictive material generates a torsional wave pulse at the position where the float is located,this pulse is transmitted back along the waveguide wire at a fixed speed and detected by the detection mechanism. By measuring the time difference between the pulse current and the torsional wave, the position of the float, that is, the position of the liquid surface, can be accurately determined Product features 1)Contact measurement 2)High precision, high stability, high reliability Long service life 4)Multiple signal output options 5)Reverse polarity protection 6)Lightning protection, anti-radio frequency interference 7)Compact structure and strong environmental adaptability 8)No need for periodic calibration and maintenance 9)Measure liquid level of tank with or without pressure 10)Isolated explosion-proof type (optional) 11)Easy installation Technical parameter: Output formï¼? 4ï½?20mAã??0ï½?5Vã??0ï½?10Vã??±5Vã??±10Vã??RS-485( varies from model to model) Linear errorï¼? superior to ±0.05%FSï¼?Sensors with a range of less than 300 mm has an error of less than 150 μm Repeaditityï¼?
