KR-939SB3 Tri-Parameter Combination Probe (Vibration, Temperature, Oil Level)
一、概述
KR-939SB3一體化三參數組合探頭（振動、溫度、油位）是冷卻塔風機安全監控系統中一種非總線結構的通用型組合探頭。它可以直接與三參數安全監控儀配接，實現單臺設備監控，也可以與多種通用二次儀表或計算機數據采集測控系統(DCS、PLC等)連接使用。
I. Overview
The KR-939SB3 three-parameter combination probe (temperature, oil level, vibration) is a general-purpose combined probe with non-bus structure used in the safety monitoring system for cooling tower fans.It can be directly connected with a three-parameter safety monitor to realize single-equipment monitoring, and can also be used with various general secondary instruments or computer data acquisition and control systems (DCS, PLC, etc.).
冷卻塔風機是生產企業的重要設備，在長期、惡劣的運行環境中，難免產生部件腐蝕、缺油磨損、材料疲勞，從而引起零部件松動、摩擦加劇、振動不平衡、抖動增大等現象，若不能及時發現處理，將引起軸承燒毀、機件損壞，甚至葉片斷裂的惡性事故。
Cooling tower fans are critical equipment in manufacturing enterprises.Under long-term and harsh operating conditions, component corrosion, oil starvation wear, and material fatigue are inevitable, leading to loose parts, increased friction, unbalanced vibration, and greater shaking.If such problems are not detected and addressed in a timely manner, they can result in serious accidents such as bearing burnout, mechanical damage, and even blade fracture.
該組合探頭為小型一體化全不銹鋼防腐結構，輸出傳送方式具有長線抗干擾能力，加上良好的密封和抗震防爆措施，使其能夠在測量現場惡劣環境下長期在線工作，是目前現代工業、國防、科研的設備安全監測單元。
This combined probe features a compact, integrated all-stainless steel anti-corrosion structure.Its output transmission mode provides long-distance anti-interference capability.Coupled with excellent sealing, shock resistance and explosion-proof measures, it enables long-term online operation in harsh on-site measurement environments.It is an indispensable equipment safety monitoring unit for modern industry, national defense and scientific research.
