WS (SX) - Series Bimetallic (Electric Contact) Temperature GaugeSuitable for on-site detection at medium and low temperatures, it can directly measure the temperature of liquids, gases, and vapors, with no mercury hazard, clear indication, robustness, and shock resistance. All instruments are made of stainless steel material, which has good waterproof and anti-corrosion properties. Electric contact bimetallic thermometer is an instrument suitable for on-site detection and automatic control of medium and low temperatures. It can directly measure the temperature of gases and automatically control or signal the temperature changes of the measured medium. This series is widely used in industries such as petroleum, chemical, metallurgical, textile, and food. |

Application of thermometer sleeve
When the process involves high pressure, high flow rate, or corrosive conditions, and the protective tube of the bimetallic thermometer itself is not suitable for such conditions, as well as when it is required that the process pipeline or equipment be a closed system before the instrument is installed, a thermometer sleeve should be used to ensure safety and normal operation. For medium and low pressure media, it is advisable to use straight or conical drilled tube thermometer sleeves; For situations where the flow rate of the measured medium is high or where high strength is required for the thermometer sleeve, a conical drilling sleeve should be selected; For situations where reducing resistance or decreasing thermal response time is required, a stepped thermowell can be used. |
