Application areas: The most commonly used pressure detection and transmission instrument is widely used in various industrial automation environments. I. Overview The JA-YB201 pressure transmitter is a compact , well-configured, and highly accurate pressure transmitter. It has two kinds of pressure measurement methods: gauge pressure and absolute pressure. It adopts the most advanced diffusion silicon sensor and ceramic sensor and its manufacturing process in foreign countries . It can be freely configured by three buttons, and can be installed with high contrast and backlit LCD display. The transmitter field data recovery, 4~20mA superimposed HART protocol digital signal, with the stability and reliability of the imported pressure transmitter . The contact with the medium is made of 316L stainless steel diaphragm or ceramic diaphragm, which can be used in various industrial occasions such as petroleum, chemical, electric power, water conservancy, metallurgy and heat. High-quality sensors and circuitry to ensure maximum performance and low cost pressure transmitter, JA-YB201 pressure transmitter in harsh environments, but also to ensure the best performance and long-term stability. Pressure transmitter with built-in ceramic capacitor , diffused silicon , ceramic piezoresistive sensor . The analog, intelligent digital live display header can be freely selected. There are a variety of process connections, which can adjust the zero point and full scale on site. Widely used in the measurement of liquids, gases and vapors in the automation industry.  Second, product features:  Ø         Easy to install, it can be installed directly or it can be mounted by bracket. Ø         Anti-frequency interference, high stability and high reliability. Ø         Gauge pressure, absolute pressure, negative pressure Ø         Temperature compensation function Ø         LED , LCD display two forms of choice Ø         Reverse power protection  Third, the application area  JA-YB201 pressure transmitter is the most commonly used sensor in industrial applications . It is widely used in various industrial self-control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military, petrochemical, oil well, Power, ships, machine tools, pipelines and many other industries.  Fourth, technical parameters  Measuring range Relative pressure Maximum measuring range 0 ~ 60Mpa Minimum measurement range 0 ~ 2Kpa Negative relative pressure Maximum measuring range -0.1 ~ +60Mpa Minimum measurement range -1 to +1 Kpa Range migration Can do standard range 10 : 1 migration Accuracy level ± 0.2% , ± 0.5% Operating Voltage 12.5 to 36VDC stability Within the specified operating temperature, the ambient temperature changes by 10 °C , the output changes ≤ ± 0.2% of the range , and the annual drift < ± 0.5% Vibration effect 200HZG is 0.01% FS on any axis, and the annual stability is better than 0.1% output signal 4 to 20 mA ; 1-5V Operating temperature -20 °C ~ 85 °C Load Resistance ≤ 1000Ω Relative humidity 95 % non-condensing Explosion-proof grade Not explosion-proof or Exiaiict4-CT6 Protection level IP65 Material sensor 96% alumina ceramic, 316L Sealing material Fluorocarbon rubber, PTFE (polytetrafluoroethylene) Instrument housing material Die-cast alloy aluminum, surface epoxy spray Main structural material 0Gr18Ni9 Fifth, the instrument selection:  model Description JA-YB201 -□ /□ /□ /□ /□ /□ /□ Instrument type K       Diffused silicon T Ceramic piezoresistive Measuring range 1 -100Kpa ～ 0Kpa ～ 2kpa ～ 60Mpa ( diffusion silicon ) 2 0Mpa ~ 60Mpa ~ 2kpa (silicon diffusion) 3 -100Kpa ~ 0Kpa ~ 50kpa ~ 60Mpa ( ceramic piezoresistive ) 4 0Mpa ~ 50kpa ~ 60Mpa (ceramic piezoresistive) Output form 1 4~20mA 2 0~10mA 3 1~5V 4 0~10V 5 4~20Ma+ live display 6 4~20Ma+Hart 7 4~20Ma+ live display +Hart Accuracy level P1 0.1 %FS P2 0.2 %FS P5 0.5 %FS Connection method M1 M20×1.5 external thread M2 M27×2 external thread G1/2 G1/2 external thread T special requirements Attachment function M0 No display M1 LCD liquid crystal display M2 LED liquid crystal display Explosion type N No explosion protection F Explosion - proof Exd II BT4  Sixth, the size normal type Seven, on-site correction  After the transmitter is properly installed, if the output signal of the transmitter is in error, it can be corrected by adjusting the zero-potentiometer “Z†of the transmitter circuit surface . Do not move the potentiometer “R†, intelligent transmitter If you need to adjust, you need to have the following two conditions: 1. The range needs to be changed. After consultation with the manufacturer, it is determined to be within the adjustment range. 2. The site has the required equipment and is operated by professional technicians.  Eight, wiring method  For the connection of various specific instruments, the pressure transmitter output model and electrical connection are as follows: Two-wire 24VDC power supply, 4--20mA output Three (four) line 24VDC power supply, 0---10mA , , 1---5VDC , 0---5VDC output 220VDC power supply, 4---20mA, 0----10mA , 1----5V , 0----5VDC output Nine, installation precautions 1 The cover must be hand-tightened and must not damage the threads. 2 sensitive parts should be tightened. 3 The wiring holes must be sealed with suitable seals. 4 If there is a wiring hole on the electronic housing, it must be plugged and tightened with a threaded plug. 5 The circuit side of the housing and the isolation layer on the wiring side must not damage the ring, and the terminal must be intact.
