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

一、概述

苏州航振KR939SB3三参数组合探头（温度、油位、振动）是冷却塔风机安全监控系统中一种非总线结构的通用型组合探头。它可以直接与三参数安全监控仪配接，实现单台设备监控，也可以与多种通用二次仪表或计算机数据采集测控系统(DCS、PLC等)连接使用。

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.).

冷却塔风机是生产企业的重要设备，在长期、恶劣的运行环境中，难免产生部件腐蚀、缺油磨损、材料疲劳，从而引起零部件松动、摩擦加剧、振动不平衡、抖动增大等现象，若不能及时发现处理，将引起轴承烧毁、机件损坏，甚至叶片断裂的恶性事故。

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.

该组合探头为小型一体化全不锈钢防腐结构，输出传送方式具有长线抗干扰能力，加上良好的密封和抗震防爆措施，使其能够在测量现场恶劣环境下长期在线工作，是目前现代工业、国防、科研的设备安全监测单元。

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.
