KR-939SB3 Tri-Parameter Combination Probe (Vibration, Temperature, Oil Level)

一、概述

KR-939SB3振動(dòng)溫度液位三參數(shù)組合探頭是冷卻塔風(fēng)機(jī)安全監(jiān)控系統(tǒng)中一種非總線結(jié)構(gòu)的通用型組合探頭。它可以直接與三參數(shù)安全監(jiān)控儀配接，實(shí)現(xiàn)單臺設(shè)備監(jiān)控，也可以與多種通用二次儀表或計(jì)算機(jī)數(shù)據(jù)采集測控系統(tǒng)(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(fēng)機(jī)是生產(chǎn)企業(yè)的重要設(shè)備，在長期、惡劣的運(yùn)行環(huán)境中，難免產(chǎn)生部件腐蝕、缺油磨損、材料疲勞，從而引起零部件松動(dòng)、摩擦加劇、振動(dòng)不平衡、抖動(dòng)增大等現(xiàn)象，若不能及時(shí)發(fā)現(xiàn)處理，將引起軸承燒毀、機(jī)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(jié)構(gòu)，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(xiàn)場惡劣環(huán)境下長期在線工作，是目前現(xiàn)代工業(yè)、國防、科研的設(shè)備安全監(jiān)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.

二、功能說明

這種應(yīng)用于風(fēng)機(jī)減速箱安全運(yùn)行監(jiān)測的組合探頭，在其內(nèi)部分別集成了測量油溫、油位、振動(dòng)信號的傳感、轉(zhuǎn)換和變送電路，直接輸出相對應(yīng)的4～20mA標(biāo)準(zhǔn)電流信號，可以配接各種通用型二次儀表或計(jì)算機(jī)數(shù)字采集監(jiān)控系統(tǒng)。

II. Function Description

This combined probe, used for safe operation monitoring of fan gearboxes, integrates built-in sensing, conversion and transmission circuits for measuring oil temperature, oil level and vibration signals respectively.It directly outputs corresponding standard 4–20mA current signals and can be used with various general-purpose secondary instruments or computer digital acquisition and monitoring systems.
