Product Name: JFA712C Steam Pneumatic Explosion Proof Differential Pressure Sensor Transmitter Model NO.: JFA712C Customized: Customized Certification: CE IP Rating: IP67 Pressure range: 0.01-0-200MPa Accuracy Grade: 0.5G Measuring Medium: Liquid Structure Type: Diffused Silicon Pressure Transmitter Type: Differential Pressure Transmitter Trademark: JFORALL Transport Package: Carton Packing Origin: Hunan, China HS Code: 9026201090 Product Description Description:JFA712 intelligent pressure transmitter. The circuit design is adopted modular design that the core is microprocessor, assisted with advanced digital isolation technique.This instrument is extremely stable and interference-free. Meanwhile, this product adopt digital compensation technology to compensate temperature and hydrostatic. The accuracy enhanced and temperature drift reduced. This product turns out to featuring high stability ,well reliability, strong self-diagnosis. The users can make configuration, setting and calibration to transmitter, by using HART communicative operator, knob in the outside shell, or button in display.Features:Small size and light weight.Range migration function, the range migration ratio is 100:1.Damping: 0~32s can be adjusted, step to 0.1s.Zero point, full scale compensation revision function.Multi-point calibration of output current.Multiple monitoring variables be shows, pressure unit can be choose.Ultralow temperature OLED displayer.(-40~70ºC).Output current root square function.Self-diagnosis and fault alarm;The EEPROM nonvolatile memory prevents the loss of data and recovers the original calibration data;The remote, on-site parameter setting and function configuration are realized through the HART communication hand operator.Technical parameters:mediumliquid, gas, steamAccuracy:≤ ±0.075% ofmeasure rangeStability:0.1%/1 year,0.25%/3 yearEnvironment temperature:-40ºC~85ºCDigital display temperature:-40ºC~70ºCThread connectG1/4 ,G1/2 .M20*1.5Measure range:differential pressure 0-0.125KPa~0-7MPa,gauge pressure 0-0.125KPa~0-42MPa,absolute pressure 0-200KPa~0-2.1MPaOutput signal:two-wires 4-20mA, conform to NAMUR NE43 specification, superimpose digital signal(HART agreement)Power supply:min main voltage 9VDC, max main voltage 45VDCDisplay:OLED display,3 lines,5 characters, with unit and stick plot displayFailure alarm:if the sensor or circuit break down, self-diagnosis function will output 3.6 or 21.0mA automatically( the users can pre-set )Reconciliation of zero point and measure range:Modify through digital communication or local button with no interference.Explosion isolated performance:explosion proof and water proof sealed case, safety essentially.Product details:Related products:Applications:Certifications:Company:Contact us:
