Pura Plus Live Trace humidity transmitter Alert

Custom processing: Brand: British Michell Model: Pura Plus Type: Live Dewpoint Transmitter measuring range: -40 ~ + 60 ° C Accuracy: ± 2 ° C Measurement object: gas Pura Plus Live Trace humidity transmitter Alert is the new Pura Plus is Michell latest requirements for wafer industry equipment size and indicators specifically designed for change. Pura Plus is an online transaction trace humidity transmitters, multiple installation leads to the production line at the end of the semiconductor factory gas supply, to monitor the application of ultra-pure inert gas. Gas distribution systems within the plant complex, involving many branches, nodes, and point of use. Therefore, after a conventional moisture monitoring point, due to a small amount of leakage, inefficient system design, component failure or process error and so cause the ingress of moisture, affect downstream use. Installed in the distribution system Pura Plus provides fast response indicates, at 20 ppb moisture level transaction response time of less than 1 ppb for 1 minute. Highlights · ppb level moisture movement for fast response · humidity ppb level sensitivity (<1 ppb) · installation of a new multi-point measurement concept · low maintenance type of status indicator lights · · You can set warning and alarm points · Modbus network compatible Multi-channel software · (UHP) gas pipeline ultrapure remote control interface detection Pura Plus Specifications Response speed <20 ppb moisture changes in one minute 1 ppb Response time humidity range 1 ppb to 20,000 ppm range 0 to 10 bar pressure Pressure rating 300 bar Leak Test 0-9 mbar l / s Working flow range 1 ~ 10 l / min Operating temperature 5 ~ 40 ° C Storage Temperature 30 ~ 70 ° C Power 20 ~ 28 V DC Power 5 W maximum external fuse Level 500 mA fast-acting two-wire Modbus ASCII data output RS485 warning and alarm output 2 Maximum voltage 40 V DC Maximum current 100 mA gas contacting material shell material stainless steel AISI 316L, electro-polished inner surface <10 Ra alumina electrolyte sensor structure upper gilded protection, the lower layer of aluminum interior volume 4.4cm weight 450g Gas Connections 1/4 "m VCR electrical interface 9? - pin D - type m Interface electromagnetic compatibility EN50081-2 and EN50082-2
