WSSX-483B隔爆雙金屬溫度計是一種適用于存在爆炸性氣體環(huán)境的溫度測量儀表，廣泛應用于石油、化工、醫(yī)藥等行業(yè)。其外殼采用鋁合金材質，通過隔爆設計，能夠有效防止內部可能產生的火花或電弧引發(fā)外部爆炸。該溫度計的測溫范圍為-80℃至+500℃，精度等級為1.5級。其保護管和連接部件通常采用不銹鋼材料，具有良好的耐腐蝕性和耐用性。

WSSX-483B隔爆雙金屬溫度計的工作原理是利用雙金屬片的熱膨脹特性。雙金屬片由兩種不同膨脹系數(shù)的金屬片疊合而成，當溫度變化時，雙金屬片會發(fā)生彎曲，從而帶動指針轉動，指示出溫度的變化。該溫度計還帶有機械電接點裝置，當溫度達到設定值時，可以觸發(fā)外部電路，實現(xiàn)自動控制或報警功能。

在價格方面，WSSX-483B隔爆雙金屬溫度計因生產廠家、規(guī)格和配置不同而有所差異。一般來說，其價格區(qū)間在幾百元到上千元人民幣不等。具體價格需要根據(jù)用戶的需求和選型參數(shù)來確定。

目前，WSSX-483B隔爆雙金屬溫度計的主要生產廠家包括上海自動化儀表有限公司、安徽天康（集團）股份有限公司、上海雙旭電子有限公司等。這些廠家均具備專業(yè)的生產技術和良好的售后服務，能夠為用戶提供優(yōu)質的產品和解決方案。

The WSSX-483B explosion-proof bimetallic thermometer is a temperature measuring instrument designed for use in environments with explosive gases. It is widely used in industries such as petroleum, chemical, and pharmaceuticals. The thermometer s casing is made of aluminum alloy and features an explosion-proof design, effectively preventing sparks or arcs inside the instrument from triggering external explosions. The temperature measuring range of the WSSX-483B is from -80°C to +500°C, with an accuracy class of 1.5. The protective tube and connecting parts are typically made of stainless steel, offering good corrosion resistance and durability.

The working principle of the WSSX-483B explosion-proof bimetallic thermometer relies on the thermal expansion characteristics of bimetallic strips. These strips are composed of two different metals with varying expansion coefficients. When the temperature changes, the bimetallic strip bends, causing the pointer to rotate and indicate the temperature change. The thermometer also features a mechanical electrical contact device that can trigger an external circuit when the temperature reaches a set value, enabling automatic control or alarm functions.

In terms of price, the cost of the WSSX-483B explosion-proof bimetallic thermometer varies depending on the manufacturer, specifications, and configuration. Generally, the price ranges from several hundred to over a thousand Chinese yuan. The specific price needs to be determined based on the user s requirements and selection parameters.

Currently, the main manufacturers of the WSSX-483B explosion-proof bimetallic thermometer include Shanghai Automation Instrument Co., Ltd, Anhui Tiankang (Group) Co., Ltd, and Shanghai Shuangxu Electronics Co., Ltd. These manufacturers all possess professional production technology and good after-sales service, providing users with high-quality products and solutions.
