產品簡介
BX/BXN系列膜片電接點壓力表采用膜片作為測壓敏感元件,并可根據不同的測量介質選用不同材料的膜片。本儀表主要用于工業過程中對氣體、液體壓力微小壓力的測量,尤其適用于腐蝕性粘稠介質(非凝固、非結晶)的微小壓力測量,并通過儀表指針的觸點與設定指針的觸點相接通(斷開)控制系統中電路的開關,以達到自動控制和自動報警功能。
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、定貨時請按表中規定的開關功能給出相應的接點名稱或編號。
2、表中雙接點連接導線為:接點2 為下限設定點,接點1 為上限;設定點,接點3 為公共端。
3、表中描述的開關功能是表示:儀表壓力指針位于小刻度值時所具有的開關功能,即壓力指針從小刻度值開始順時針動時的開關狀態,當壓力指針逆時針轉動時,實現的開關功能相反。
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.
