PUR-TX line of high-purity gas dew point transmitter

Custom processing: Yes Brand: British Michell Model: PUR-TX Type: Online Dewpoint Transmitter measuring range: -120 ~ -40 ° C Accuracy: ± 2 ° C measurement object: PUR-TX high purity gases of high purity gas dew point transmitter / Live ultrapure gas dew point in many applications, such as the semiconductor industry, the gas residual moisture during the processing for the normal functioning of vital. All along, keep track of the moisture measurements are a difficult, you need to use complex moisture analyzers or expensive analytical techniques. However Michell Instruments introduced to the market at present is simple, economical and very effective solution for online measurement dew point value, the lower limit as low as amazing -120 ° C (equivalent to less than 1 ppbV). Pura transmitter is based on Michell Instruments impedance dew point many years of professional experience in the production and calibration of sensors, combined with standard industrial materials and manufacturing processes, to create a first applied to the semiconductor manufacturing industry and the application of low-cost ultra-pure gases level transmitter. Highlights · Measuring limit -120 ° C dew point (1 ppbV 1/10 billion) in · measuring stable, simple and reproducible sampling device · Highly integrated analog and digital outputs · · · Compact VCR installation process interface · Compact design · Display / Alarm unit Optional Specifications Sensor Type Michell Ceramic Moisture Sensor Range -120 ~ -40 ° C dew point (check to -100 ~ -40 ° C) accuracy of ± 1 ° C -40 ~ -60 ° C; ± 2 ° C -61 ~ -100 ° C; ± 4 ° C -101 ~ -120 ° C (estimated) Resolution 0.1 ° C -40 ~ -79.9 ° C; 1 ° C -80 ~ -100 ° C; 1 ~ 3 ° C -100 ~ -120 ° C pressure lowest 10-9 torr; 24 MPa maximum gas flow rate of 1 ~ 5 Nl / min Electrical power is usually 24 V DC, 10 V ~ highest minimum 28 V, 25 mA maximum current output 4 -20 mA output, the corresponding range by special software to adjust, adjust the range from 1 ~ 80 ° C (standard provided) Maximum load = 100 Ω + 50 Ω x (V power supply -8) output error status to the standard output error message as follows: 23 20 mA = super cap;; mA = sensor fault 4 mA = lower limit of the mechanical properties of the sensor sleeve super stainless steel, 0.1-0.2 Ra polished gas connections within m plating port Premium or OEM type: "m VCR interface Pura Sensor Type:?? ?
