Product Name: LCD Display Rtd Output Current Signal Ex-Proof Thermal Resistance Model NO.: WZP Material: Resistance Display: Digital Usage: Industrial Accuracy: a & B Standard: Celsius/Fahrenheit Phase: Single Trademark: Shuang huan Transport Package: Carton or Plywood Origin: China Jiangsu China HS Code: 9025191000 Product Description Product description:Integrated RTD can measure temperature and transmit the same time. They are formed when 2 wire system temperature transmitter lblock (SBR, SBWZ) is installed into the head of assembled RTD and MIRTD. They can measure temperature in liquid, vapor or steam during the manufacture process, and transmit 4~20mA current output which has a linear relationship with the temperature. They are used broadly in electrical, metallugy, petroleum, chemical, textile, medicineand food industries national defense and other research.Other description:The quality standard is : JB/T8623-1997 , and according to ISO9001:2008 to control the quality.Each product has to inspect temperature test by calibrate oven,appearance test,insulation test,wiring connection test, etc. We ask our supplier provide test report of raw material, each electrical element has to detect, so every finished product has factory test report and data record.We have more than 10 sets temperature calibrate oven for calibrate the different temperature,the highest temperature can be made to 500ºC, the longest immersion length can be made to 10m, and also NCM,milling machine,grinding machine from Japan to ensure the accuracy of the spare part. Self-production proportion of spare part up to 90%Capability of product research and development: Every series product team is consist of a senior engineer and several technical engineers. When we receive the technical request different to exist product, we can customize the product by technical drawing or customize according to the sample.The sampling period is 20 workdays. Feature:1.Wide measuring range.Compared with the traditional instruments, it extend the temperature measurement range.2.Widely application scope.Add protective tube, can raise the performance of high-temperature resistant, corrosive-resistant, high-pressure resistant, abrase-resistant, it expand the application scope widely.3.Convenient to control automaticly and centralization of control4.As the tranditional temperature sensor, it matched display instrument or record instrument to use, it can display the precise temperature, and also convenient to control automaticly and centralized.5.Armoured unique structure.Sheath restrictive coating structure raise the level of the sensitivity, improve the availability of the material,can curved measured, greatly extend the measure length.It has the strong pollution-resistant performance and mechanical intensity.Technology:Input signal: TC: B, S, K, E, J, T RTD: Pt100Output signal: As 4~20mA DC, within measuring range, has a linear relationship with temperatureBasic precision: ±0.5%F.S for TC; ±0.2%F.S for RTDTransmission model: two-wire systemDiect current source: minimum 12V, maximum 30V, Normal 24VLoad resistance: calculate maximum load with the following formula: RL(max)=50(U-12) U: direct current voltage of transmitter Under normal voltage of transmitter Under normal voltage:24V RL(max)=50(24-12)=600Ω (max)Normal working conditions: a. Enviromental temperature > -25 to 85ºC (special demand: ~40 to 90ºC) b. Relative humidity: 5~95% c. Machine vibration: 10~150 Hz, A=0.15mm d. Atmosphere free from corrosive media to transmitterElectrical magnetic interference: When radio with 20~1000MHz, 5W power operates 0.5m from the transmitter, the output chane of the transmitter should be less than ±0.15%F.S Temperature deviation: when environmental temperature change by 1ºC, origin and space changes are ±0.15%F.S and ±0.1%F.S respectivelyTypeGraduationMeasuring range( ºC)Thermal resistancePT100-200~+50 -100~+50 -50~+50 -50~+100 0~50 0~100 0~150 0~200 0~300 0~400 0~500 200~400 200~500PT100~150 0~200 0~300 0~500 0~750 0~850 50~100 200~400 ~50~+50Copper resistanceCu50-50~+50 -50~+100 -50~+150 0~50 0~100 0~150
