CRESSTO壓力表DMU-JB系列簡(jiǎn)介
數(shù)字壓力表和壓力計(jì)DMU-JB是一種電池供電的手持服務(wù)和車間儀表，廣泛應(yīng)用于工業(yè)、電力工程、加熱和燃燒技術(shù)、空調(diào)、通風(fēng)、實(shí)驗(yàn)室等領(lǐng)域，其質(zhì)量尤其優(yōu)于液柱壓力計(jì)（U形管）。DMU-D儀表用于測(cè)量相應(yīng)壓力下的壓差，該壓力差與額定范圍相當(dāng)。無(wú)法測(cè)量相應(yīng)高壓下的壓差，例如在氣體壓力分配系統(tǒng)中的流量板上。對(duì)于這些測(cè)量，DMU-P儀器可以測(cè)量靜態(tài)壓力的壓差，該壓差高達(dá)額定壓差的100倍，但最大為1兆帕。當(dāng)其中一個(gè)壓力輸入未連接時(shí)，儀表測(cè)量相對(duì)于大氣壓力的相對(duì)超壓或欠壓。被測(cè)介質(zhì)只能是非腐蝕性氣體，如空氣、氮?dú)獾?。DMU壓力表、JB型為火花安全型，標(biāo)記為I M1 Ex ia i MA，可用于甲烷和/或易燃粉塵發(fā)生的礦山，或標(biāo)記為II 2G Ex ia IIAT4 GB，可用于爆炸性氣體環(huán)境（1區(qū)）。
儀器安裝在一個(gè)塑料外殼從ABS。火花安全版的一個(gè)不可分割的部分是一個(gè)皮箱。儀器由對(duì)開鍵盤上的按鈕控制，該按鈕可打開/關(guān)閉儀器、可能的零點(diǎn)校正和打開時(shí)間濾波器，該按鈕可讀取輸入脈沖壓力下的平均值。入口的外徑為5毫米，用于連接介質(zhì)的壓力。有關(guān)測(cè)量壓力的數(shù)字?jǐn)?shù)據(jù)顯示在3.5圖LCD顯示屏上，單位為pa或kpa，與標(biāo)稱范圍的差異為0.1%。一個(gè)正值對(duì)應(yīng)于超壓，一個(gè)負(fù)值對(duì)應(yīng)于欠壓，在壓差測(cè)量時(shí)，正值對(duì)應(yīng)于正壓輸入上的較高壓力。該儀器可用于測(cè)量200%的額定壓力范圍內(nèi)的壓力。根據(jù)協(xié)議，也可以提供用其他壓力單位校準(zhǔn)的DMU儀表。
The digital pressure gauge and manometer DMU-JB is a battery-operated handheld service and workshop instrument, intended for wide use in industry, power engineering, heating and combustion technology, air-conditioning, ventilation, laboratories, etc. Its qualities especially come out compared with liquid column manometers (U-tubes). The DMU-D instrument is used for measuring pressure differences at corresponding pressure which is comparable with the nominal range. It is not possible to measure pressure differences at high corresponding pressure, eg. on flow plates in gas pressure distribution systems. For these measuring is intended the DMU-P instrument, which enables measuring of pressure differences on the static pressure up to 100 times higher than the nominal differential pressure, but max. 1MPa. When one of the pressure inputs is not connected, the instruments measure relative overpressure or underpressure against the atmospheric pressure. The measured medium can only be non-aggressive gas, eg. air, nitrogen, etc. The DMU gauges, version JB are spark secure types marked I M1 Ex ia I Ma, which can be used in mines with occurrence of methane and/or flammable dust or marked II 2G Ex ia IIAT4 Gb, which can be used in areas with explosive gas atmosphere (Zone 1).
The instrument is mounted into a plastic casing from ABS. An inseparable part of the spark secure version is a leather case. The instrument is controlled by means of buttons on a folio keyboard which enable switching on//off the instrument, possible zero correction and switching on the time filter, which enables reading the mean value at the pulsating pressure on the input. Inlets with the external diameter 5 mm are used for connecting the pressure of the medium. Digital data about the measured pressure are displayed on a 3.5-figure LCD display in Pa or kPa with differentiability 0.1% from the nominal range. A positive value corresponds with overpressure, a negative one to underpressure, at differential measuring a positive value corresponds with higher pressure on the positive pressure input. The instrument can be used for measuring pressure up to 200% of the nominal pressure range. Based on an agreement, it is possible to supply DMU instruments calibrated also in other pressure units.
