Yam khoom tseem ceeb
- Standardized Performance:Tsim los xa cov ntsuas kub zoo ib yam thiab raug rau kev saib xyuas kev siv yooj yim.
- Compact Head-Mount Design:Fits yooj yim rau hauv ntau hom kev sib txuas taub hau thiab vaj tse, ua kom yooj yim installation thiab txo cov kev xav tau ntawm thaj chaw.
- HART® Protocol Support:Ua kom muaj kev sib txuas lus tsis sib haum xeeb nrog kev tswj hwm rau kev teeb tsa chaw taws teeb, kev daws teeb meem, thiab kev tswj cov cuab yeej cuab tam.
- Universal Sensor Inputs:Txhawb ntau yam ntawm RTD, thermocouple, ohm, thiab millivolt inputs los muab cov ntawv thov siab tshaj plaws.
- Txhim khu kev ntseeg tau:Ua kom muaj kev ruaj ntseg hauv kev lag luam, txhawb nqa peb tus nqi tseem ceeb ntawm "kev tsim kho kom zoo rau kev txhawb nqa kev loj hlob".
Kev Lag Luam Terminology & Application Scenarios
Raws li tus khub tau cog lus rau koj txoj kev vam meej, peb muab rosemount 248 lub taub hau mount kub transmitter rau hauv ntau yam kev pabcuam engineering. Lub tshuab xa hluav taws xob no zoo tagnrho rau HVAC systems, kev tsim tshuaj, thiab kev ua zaub mov thiab dej haus qhov twg lub voj voog meej -powered 4-20mA signals yuav tsum tau. Los ntawm kev siv tus qauv txias-kev them nyiaj sib txuas thiab xa tawm-sensor txuam, nws ua kom cov ntaub ntawv muaj kev ncaj ncees thoob plaws cov khoom siv hluav taws xob thiab cov tso tsheb hlau luam. Txawm hais tias koj tab tom tswj hwm qhov kub thiab txias lossis cov txheej txheem tshwj xeeb, peb pab neeg ua haujlwm koom tes nrog koj kom ua tiav "cov txiaj ntsig yeej-yeej" thiab txhim kho koj qhov kev sib tw tseem ceeb los ntawm "kev tswj hwm raws li lub hauv paus.
