BX/BXN系列膜片電接點(diǎn)壓力表采用膜片作為測壓敏感元件，并可根據(jù)不同的測量介質(zhì)選用不同材料的膜片。本儀表主要用于工業(yè)過程中對(duì)氣體、液體壓力微小壓力的測量，尤其適用于腐蝕性粘稠介質(zhì)（非凝固、非結(jié)晶）的微小壓力測量，并通過儀表指針的觸點(diǎn)與設(shè)定指針的觸點(diǎn)相接通（斷開）控制系統(tǒng)中電路的開關(guān)，以達(dá)到自動(dòng)控制和自動(dòng)報(bào)警功能。
 
PRODUCT  OVERVIEW
BX/BXN Diaphragm electric contacts pressure gauge adopts diaphragm as sensitive
element, and it could choose different materials baed on different measure mediums. The
pressure gauge mainly applys to measure the micropressure of gas, liquid in industry
course, especially fits to medium of corrosion and viscidity (non-solidification & non-crystal).The pointer of instrument will make contacts turn on or cut with the contacts of set fingr,causing the cut and turn-on of control system for the purpose of automatic control and alarm.

說明：1、定貨時(shí)請(qǐng)按表中規(guī)定的開關(guān)功能給出相應(yīng)的接點(diǎn)名稱或編號(hào)。
2、表中雙接點(diǎn)連接導(dǎo)線為：接點(diǎn)2 為下限設(shè)定點(diǎn)，接點(diǎn)1 為上限；設(shè)定點(diǎn)，接點(diǎn)3 為公共端。
3、表中描述的開關(guān)功能是表示：儀表壓力指針位于小刻度值時(shí)所具有的開關(guān)功能，即壓力指針從小刻度值開始順時(shí)針動(dòng)時(shí)的開關(guān)狀態(tài)，當(dāng)壓力指針逆時(shí)針轉(zhuǎn)動(dòng)時(shí)，實(shí)現(xiàn)的開關(guān)功能相反。
1. When ordering, please specify the name or No. of contacts referring to the table.
2. Leads of single or double contacts: lower limits is contact 2, upper limits setpoint is contact 1, contact 3 is public port.
3. Turn on and cut function details: The table shows the turn on and cut situations as pointer moves deasil, and the function is opposite while the pointer moves widdershins.
