MT Series Combination Level/Temperature Sensors Madison Company offers many of its liquid level switch products with temperature sensing capabilities. The incorporation of either thermocouples, RTD sensors, thermistors or bimetal switches can offer the user the ability to determine level and temperature in the vessel and save the cost of having dual mounting considerations. Linked with Madison’s cable assemblies and controllers, combination sensors can provide a readout of the environmental conditions, as well as the capability to turn associated equipment on and off. Switches shown above are representative of our combination level/temperature sensor capabilities. (Models MT3920-1, MT5600-1 and MT8000-1) The temperature limitations are dependent on the materials selected for the level switch itself. As an example, the subminiature Model MT3920-1 is a polypropylene level switch with a Type J thermocouple. The thermocouple temperature range is -40˚C to 250˚C (-40˚F to 482˚F), while the polypropylene is rated to 105˚C (221˚F). Another example is a single-point 316 stainless steel liquid level switch engineered for use in a 300˚C (572˚F) environment. Other considerations that Madison Company makes are the position of the sensors, time response and signal conditioning. Time response testing on selected MT configurations has shown a typical response time to be 20 to 25 seconds.
