LCD display smart Temperature transmitter which can equip PT100, PT1000, RTD with 4-20ma RS485 output

Product Overview:  HT218M  LCD isolation intelligent temperature transmitter is used for RTD, thermocouple (TC), resistance  (Ω),   signal  input,  two-wire  system  4-20mA  analog  output,  and  the configuration is via RS485 (MODBUS RTU protocol) or HART protocol.Features:Input signal supports 2 RTDs, 10 thermocouplesInput signal is fully switchable4~20mA output, RS485,HART optionalThermocouple cold end compensationResponse time≤700mSInput and output isolation, good anti-interference effect   Parameters:Input signalRTDs and thermocouplesCold-end compensation temperature range-20~70ºCCompensation accuracy±1ºCOutput signal4~20mA, or 4~20mA plus HART protocolLoad resistanceRL≤(Ue- 14)/0.021Overflow alarm output currentat the upper and lower limits.IH=21mA, IL=3.8mAPower supply DC16~40VTemperature drift0.015%FS/ºCResponse timereaches 90% of the final scale within 1sAmbient temperature in use-20~70ºCDielectric strength1500Vrms(in 1 min)electrical insulation resistance>=100MΩ (500VDC)   Input type and transmission accuracy  Input CodeTypeMeasuring temperature  RangeMin. measuring rangeConversion accuracy(whichever is greater)RTDPt100Pt100-200.0~850.0ºC20ºC±0.1%FS or ±0.2ºCCu50Cu50-50.0~150.0ºC20ºC±0.1%FS or ±0.2ºCTC(thermocouples)TC-BB400~1800ºC500ºC±0.1%FS or ±1.5ºCTC-EE-100~1000ºC50ºC±0.1%FS or ±0.5ºCTC-JJ-100~1200ºC50ºC±0.1%FS or ±0.5ºCTC-KK-180~1372ºC50ºC±0.1%FS or ±0.5ºCTC-NN-180~1300ºC50ºC±0.1%FS or ±0.5ºCTC-RR-50~1768ºC500ºC±0.1%FS or ±1.5ºCTC-SS-50~1768ºC500ºC±0.1%FS or ±1.5ºCTC-tT-200~400ºC50ºC±0.1%FS or ±0.5ºCNote:1. The above accuracy data is tested under the condition of ambient temperature of 20ºC±2ºC.2. The output accuracy "%" is relative to the set range.3. Thermocouple measurement also need to add the cold end compensation error, internal cold end compensation error ≤ ± 1 ºC.Structure Drawing:  Wiring:Application:Related Products:Certification:FAQ:1.    Q: Are you manufacturer or trading company?        A: We are manufacturer which focuses on sensor for 10 years.2.    Q: What's your quality control system?        A: MC, ISO9001, CE Certificated.3.    Q: What is the warranty of your products?        A: Our warranty time is 18 months after shipment.  4.     Q: What is lead time of your product?         A: Normally, our factory lead time is within 10~15 working days for products without customization.
