Product Introduction
The WZP-231 waterproof junction box is a temperature sensor housing designed for industrial applications, featuring fixed-thread connection and waterproof construction. It works with display instruments, recorders and electronic regulators to measure temperatures from -200°C to 420°C for liquids, vapors, gases and solid surfaces. The stainless steel housing provides mechanical durability and corrosion resistance, while the sealed junction box maintains reliable performance in dusty or humid environments.41114
Key Features
This product utilizes a double-sealed structure with labyrinth seals and fasteners to achieve dustproof/waterproof performance. The platinum RTD sensing element ensures fast thermal response (T0.5≤40S) and high measurement accuracy. Standard 12mm diameter protection tubes are available with customizable insertion depths (75-1200mm). The fixed-thread installation simplifies field deployment, and dual-element versions (WZP2-231) support simultaneous signal output for redundant monitoring systems. The design accommodates both 3-wire and 4-wire connection methods.51419
Technical Specifications
Technical highlights include: self-heating effect ≤0.30°C at 5mA; insulation resistance ≥100MΩ (10-100VDC); nominal pressure 6MPa (static, ambient). The platinum wire sensing element is uniformly wound on insulated frames for gradient measurement accuracy. Optional 304/316L stainless steel protection tubes address corrosive media. Compact design adapts to space-limited installations with customizable length/depth configurations. The waterproof terminal compartment withstands washdown conditions in food/pharmaceutical applications.111822
Typical Applications
Ideal for steam pipelines, chemical reactors, and food processing lines requiring splash resistance. Performs reliably in outdoor oil storage tanks, wharf pipelines exposed to rainwater, and pharmaceutical cleanrooms where sealing prevents contamination. The stainless steel construction withstands high-temperature media in boilers and synthesis towers. Single/Dual-element options serve basic measurement or redundant monitoring needs across industries including power generation, petrochemicals and HVAC systems.2523
Service Support
We offer technical consultation and custom solutions for special requirements including alternative materials, insertion lengths and mounting interfaces. All units undergo multi-stage testing to verify step-response characteristics. Enhanced versions are available for extreme acid/alkali environments. Detailed installation manuals accompany each product to facilitate system integration. Custom OEM configurations can be developed for large-volume applications.101723

編輯本段防水接線盒的材料
目前世界上生產(chǎn)標(biāo)準(zhǔn)防水接線盒的原材料主要有：ABS工程塑料、聚碳酸酯(PC)、PC/ABS、玻璃纖維增強(qiáng)聚酯、不銹鋼。根據(jù)不同的現(xiàn)場環(huán)境，用戶可以選擇滿足現(xiàn)場使用要求的材料。
ABS工程塑料：丙烯腈-丁二烯-苯乙烯共聚物（Acrylonitrile-Butadiene-Styrene，簡稱ABS)是一種通用型熱塑性聚合物，ABS性能特征：剛性好、沖擊強(qiáng)度高、耐熱、耐低溫、耐化學(xué)藥品性、機(jī)械強(qiáng)度和電器性能，易于加工，加工尺寸穩(wěn)定性和表面光澤好，容易涂裝、著色，還可以進(jìn)行噴涂金屬、電鍍、焊接和粘接等二次加工性能。由于ABS的特性結(jié)合了其三種組分的特點(diǎn)，使其具有的綜合性能，成為電器元件、家電、計算機(jī)和儀器儀表選的塑料之一。
聚碳酸酯(PC)材料：聚碳酸酯(簡稱PC)是分子鏈中含有碳酸酯基的高分子聚合物，根據(jù)酯基的結(jié)構(gòu)可分為脂肪族、芳香族、脂肪族-芳香族等多種類型。其中由于脂肪族和脂肪族-芳香族聚碳酸酯的機(jī)械性能較低，從而限制了其在工程塑料方面的應(yīng)用。目前僅有芳香族聚碳酸酯獲的了工業(yè)化生產(chǎn)。由于聚碳酸酯結(jié)構(gòu)上的特殊性，現(xiàn)已成為五大工程塑料中增長速度快的通用工程塑料。
PC/ABS材料：聚碳酸酯和丙烯腈-丁二烯-苯乙烯共聚物和混合物，是由聚碳酸酯（Polycarbonate）和聚丙烯精（ABS）合金而成的熱可塑性塑膠，結(jié)合了兩種材料的優(yōu)異特性，ABS材料的成型性和PC的機(jī)械性、沖擊強(qiáng)度和耐溫、抗紫外線（UV）等性質(zhì)，可廣泛使用在汽車內(nèi)部零件、事務(wù)機(jī)器、通信器材、家電用品及照明設(shè)備上。
