WSSX-483B隔爆双金属温度计是一种适用于存在爆炸性气体环境的温度测量仪表，广泛应用于石油、化工、医药等行业。其外壳采用铝合金材质，通过隔爆设计，能够有效防止内部可能产生的火花或电弧引发外部爆炸。该温度计的测温范围为-80℃至+500℃，精度等级为1.5级。其保护管和连接部件通常采用不锈钢材料，具有良好的耐腐蚀性和耐用性。

WSSX-483B隔爆双金属温度计的工作原理是利用双金属片的热膨胀特性。双金属片由两种不同膨胀系数的金属片叠合而成，当温度变化时，双金属片会发生弯曲，从而带动指针转动，指示出温度的变化。该温度计还带有机械电接点装置，当温度达到设定值时，可以触发外部电路，实现自动控制或报警功能。

在价格方面，WSSX-483B隔爆双金属温度计因生产厂家、规格和配置不同而有所差异。一般来说，其价格区间在几百元到上千元人民币不等。具体价格需要根据用户的需求和选型参数来确定。

目前，WSSX-483B隔爆双金属温度计的主要生产厂家包括上海自动化仪表有限公司、安徽天康（集团）股份有限公司、上海双旭电子有限公司等。这些厂家均具备专业的生产技术和良好的售后服务，能够为用户提供优质的产品和解决方案。

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.
