CRESSTO压力表DMU-JB系列简介

数字压力表和压力计DMU-JB是一种电池供电的手持服务和车间仪表，广泛应用于工业、电力工程、加热和燃烧技术、空调、通风、实验室等领域，其质量尤其优于液柱压力计（U形管）。DMU-D仪表用于测量相应压力下的压差，该压力差与额定范围相当。无法测量相应高压下的压差，例如在气体压力分配系统中的流量板上。对于这些测量，DMU-P仪器可以测量静态压力的压差，该压差高达额定压差的100倍，但最大为1兆帕。当其中一个压力输入未连接时，仪表测量相对于大气压力的相对超压或欠压。被测介质只能是非腐蚀性气体，如空气、氮气等。DMU压力表、JB型为火花安全型，标记为I M1 Ex ia i MA，可用于甲烷和/或易燃粉尘发生的矿山，或标记为II 2G Ex ia IIAT4 GB，可用于爆炸性气体环境（1区）。

仪器安装在一个塑料外壳从ABS。火花安全版的一个不可分割的部分是一个皮箱。仪器由对开键盘上的按钮控制，该按钮可打开/关闭仪器、可能的零点校正和打开时间滤波器，该按钮可读取输入脉冲压力下的平均值。入口的外径为5毫米，用于连接介质的压力。有关测量压力的数字数据显示在3.5图LCD显示屏上，单位为pa或kpa，与标称范围的差异为0.1%。一个正值对应于超压，一个负值对应于欠压，在压差测量时，正值对应于正压输入上的较高压力。该仪器可用于测量200%的额定压力范围内的压力。根据协议，也可以提供用其他压力单位校准的DMU仪表。

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.
