This combination liquid level and temperature switch provides dual protection for critical liquid applications. The float in this combination sensor switches from open to closed (NC) or closed to open (NO) for rising liquid levels in your process tank. Additionally, the output of the internal thermocouple switch is designed to be open when your process temperature rises to a predetermined limit (NC) or closes when your process temperature rises to a predetermined limit (NO). The dimensions of the temperature switch necessitate the use of a 1” longer stem with a larger (1/2”) diameter.
Temperature switches are ideal for interfacing with control systems with known limits on temperature. Higher temperature potting is used to allow for temps up to 120C. One of the many ideal applications is for heating liquids within a process where heating elements are placed inside a vessel. These heating elements need to be constantly immersed in liquid and not exposed to air or else they can cause damage. By combining liquid level detection and temperature limit switch detection, one can confidently reduce the risk of process damage due to loss of liquid in the vessel.
These higher temperature devices are also ideal for fast food fryers and food processing equipment. Resistive Temperature Detectors, or RTDs, provide accuracy and linearity at a low cost. Good for general-purpose appliance use and medical applications.
Food and beverage and agricultural markets are an ideal use for combination liquid level and temperature sensors. These sensors can help agricultural workers make sure that they are using appropriate amounts of cleaning solutions and water. Temperature sensors can help farmers make sure that the cleaning solutions they use are heated to the temperatures that are appropriate for their circumstances so that the food they deliver to the market will be free of contamination and safe for consumption. Sensors can allow workers to monitor conditions throughout the CIP process and make sure they are always at correct levels. For restaurant and home appliances where both liquid levels and temperature need to be monitored precisely with a minimum of available mounting space, combination level temperature sensors are an ideal solution.
