High humidity can significantly impact the performance and lifespan of liquid level transmitters, leading to inaccurate readings, corrosion, and even complete failure. In this blog, I will share some effective protection measures for liquid level transmitters in such conditions. <a href=\"https:\/\/www.iges-inst.com\/liquid-level-transmitter\/\">Liquid Level Transmitter<\/a><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.iges-inst.com\/uploads\/46626\/small\/tth200-abb-temperature-transmitter74373.jpg\"><\/p>\n<h3>1. Enclosure Design<\/h3>\n<p>One of the most fundamental protection methods is the use of a proper enclosure. A well &#8211; designed enclosure can shield the liquid level transmitter from direct contact with moisture in the air.<\/p>\n<ul>\n<li><strong>Sealed Enclosures<\/strong>: Opt for enclosures that are IP (Ingress Protection) rated. For high &#8211; humidity environments, an IP65 or higher rating is recommended. An IP65 &#8211; rated enclosure is dust &#8211; tight and protected against water jets from any direction. This means that even if there is water splashing or high humidity in the form of mist, the internal components of the transmitter are well &#8211; protected. For example, we use enclosures made of high &#8211; quality plastics or stainless steel. These materials are not only durable but also resistant to corrosion caused by moisture.<\/li>\n<li><strong>Ventilation and Drainage<\/strong>: While a sealed enclosure is essential, it is also important to consider ventilation. Some enclosures are designed with small vents that allow air to circulate while preventing large amounts of moisture from entering. Additionally, drainage holes can be incorporated at the bottom of the enclosure. These holes ensure that any condensed water inside the enclosure can drain out, reducing the risk of water pooling and causing damage to the electronic components of the transmitter.<\/li>\n<\/ul>\n<h3>2. Coating and Surface Treatment<\/h3>\n<p>Applying special coatings to the components of the liquid level transmitter can enhance its resistance to humidity.<\/p>\n<ul>\n<li><strong>Conformal Coatings<\/strong>: Conformal coatings are thin protective layers applied to printed circuit boards (PCBs) and other sensitive electronic parts. These coatings can be made of materials such as acrylic, silicone, or urethane. They provide a barrier against moisture, dust, and chemicals. In high &#8211; humidity environments, a conformal coating can prevent water from reaching the conductive tracks on the PCB, which could otherwise cause short &#8211; circuits or corrosion. For instance, we use a high &#8211; quality acrylic conformal coating on our transmitters&#8217; PCBs. This coating is easy to apply and provides excellent protection against moisture.<\/li>\n<li><strong>Surface Treatment of Metal Parts<\/strong>: Metal parts of the liquid level transmitter, such as the housing or the sensing element, can be treated to prevent corrosion. Galvanizing, anodizing, or powder &#8211; coating are common surface treatment methods. Galvanizing involves applying a layer of zinc to the metal surface, which acts as a sacrificial anode, protecting the underlying metal from corrosion. Anodizing creates a protective oxide layer on the metal surface, increasing its resistance to corrosion. Powder &#8211; coating provides a thick, durable, and moisture &#8211; resistant layer on the metal parts.<\/li>\n<\/ul>\n<h3>3. Humidity &#8211; Resistant Materials<\/h3>\n<p>Selecting the right materials for the construction of the liquid level transmitter is crucial for its performance in high &#8211; humidity environments.<\/p>\n<ul>\n<li><strong>Sensor Materials<\/strong>: The sensing element of the liquid level transmitter is the most critical part. For high &#8211; humidity applications, we use sensors made of materials that are not affected by moisture. For example, ceramic sensors are a popular choice. Ceramic is a non &#8211; porous material, so it does not absorb moisture. This ensures that the sensor&#8217;s performance remains stable even in high &#8211; humidity conditions.<\/li>\n<li><strong>Electrical Connectors<\/strong>: Electrical connectors are also vulnerable to moisture. We use connectors made of materials with high &#8211; humidity resistance, such as gold &#8211; plated connectors. Gold is a noble metal that does not corrode easily, making it ideal for use in humid environments. The gold plating on the connectors provides a reliable electrical connection and prevents corrosion that could lead to signal loss.<\/li>\n<\/ul>\n<h3>4. Environmental Monitoring and Control<\/h3>\n<p>In addition to physical protection measures, it is also beneficial to monitor and control the environment around the liquid level transmitter.<\/p>\n<ul>\n<li><strong>Humidity Sensors<\/strong>: Installing humidity sensors in the vicinity of the liquid level transmitter can help monitor the humidity levels. If the humidity exceeds a pre &#8211; set threshold, an alarm can be triggered. This allows for timely action to be taken, such as increasing ventilation or taking other protective measures. For example, in some industrial applications, we integrate humidity sensors into the control systems of the liquid level transmitters.<\/li>\n<li><strong>Dehumidification Systems<\/strong>: In areas where high humidity is a persistent problem, dehumidification systems can be installed. These systems can reduce the humidity levels in the air, creating a more favorable environment for the liquid level transmitter. For instance, in a storage facility with a large number of liquid level transmitters, a central dehumidification system can be used to maintain a stable humidity level.<\/li>\n<\/ul>\n<h3>5. Regular Maintenance and Inspection<\/h3>\n<p>Regular maintenance and inspection are essential to ensure the long &#8211; term performance of liquid level transmitters in high &#8211; humidity environments.<\/p>\n<ul>\n<li><strong>Cleaning<\/strong>: Periodically clean the enclosure and the external parts of the transmitter to remove any dust or moisture that may have accumulated. Use a soft, dry cloth to wipe the surface. For more thorough cleaning, a mild cleaning agent can be used, but make sure to dry the parts completely after cleaning.<\/li>\n<li><strong>Calibration<\/strong>: High humidity can sometimes affect the accuracy of the liquid level transmitter. Therefore, regular calibration is necessary. We recommend calibrating the transmitter at least once a year or more frequently if the environment is particularly harsh. Calibration ensures that the transmitter provides accurate and reliable readings.<\/li>\n<li><strong>Component Replacement<\/strong>: Inspect the components of the transmitter regularly, especially the seals and gaskets. Over time, these parts may deteriorate due to exposure to moisture. If any components show signs of wear or damage, replace them immediately to prevent further problems.<\/li>\n<\/ul>\n<p>In conclusion, protecting liquid level transmitters in high &#8211; humidity environments requires a comprehensive approach that combines proper enclosure design, coating and surface treatment, use of humidity &#8211; resistant materials, environmental monitoring and control, and regular maintenance and inspection. By implementing these measures, we can ensure that our liquid level transmitters perform reliably and accurately in even the most challenging humidity conditions.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.iges-inst.com\/uploads\/46626\/small\/rosemount-8705-magnetic-flow-meter17255.jpg\"><\/p>\n<p>If you are in need of high &#8211; quality liquid level transmitters that can withstand high &#8211; humidity environments, or if you have any questions regarding the protection of these devices, please feel free to contact us.
