| Madison Temperature Sensors: offered in several standard designs, as well as application-specific designs for the OEM |
|
Temperature Measurement Devices
Temperature probes from Madison Company – including thermocouple probes, resistance temperature detectors (RTDs), thermistors and thermal switches – determine temperature by utilizing proven sensing technologies. Our extensive design and engineering expertise allows us to meet all of your unique temperature sensing challenges.
Madison has over 50 years of experience incorporating temperature sensors into liquid level switch products. Our standalone temperature probe line compliments our capability to design and manufacture application-specific temperature sensors and combination level-temperature switches.
We also offer a selection of versatile temperature sensor kits, which include a temperature probe and indicator or controller. Madison-Omni® RTDs are also available, featuring integrated user-programmable controls.

Thermocouple probes are simple and rugged, making them ideal for measuring environmental temperatures in industrial applications such as engines, ovens, dishwashers and heaters. Madison offers J, T and type K thermocouples in configurations ranging from bare wire to MgO-insulated, 316 stainless steel sheathed probes. A variety of lead termination options are available, including flying leads and industry-standard plugs and heads. Click below to review our specific Thermocouple offerings:

Resistance Temperature Detectors (RTDs)
RTD temperature probes provide a change in physical parameter (such as resistance or output voltage) that corresponds to a temperature change. RTDs offer platinum thin-film accuracy and stability and are used in many process, food and HVAC applications. They are available with a variety of process connection styles and insulation, and they can interface with a 4-20 mA connection. Click below to review our specific Thermocouple offerings:

Madison-Omni® RTD Temperature Sensors
These sensors provide the accuracy of RTD probes with the easy-to-use convenience of the user-programmable Madison-Omni® display interface. This compact unit features adjustable limits and alarm points, with an integrated LED alarm light. |

Thermistors (Thermally Sensitive Resistors)
Thermistors are highly accurate, but they offer a limited temperature range. They are offered in either NTC (negative temperature coefficient), where the resistance drops in a nonlinear fashion with the temperature’s rise, or PTC (positive temperature coefficient), where the resistance increases as the temperature rises. Their high output and fast response time make them popular for a variety of process, food and HVAC applications. |

Bi Metal Snap Action Switches
Bi Metal Snap Action Switches are relatively inexpensive, bimetallic temperature sensors. They use either creep or snap action and are often utilized as an inexpensive over-temperature thermal cutoff. |

|
Temperature Sensor Kits
Temperature sensor kits provide the plug-and-use “out of the box” ability for temperature measurement and/or process control. Madison’s kits include either a 316 stainless steel thermocouple probe or RTD, connected to either a full-featured programmable controller or digital indicator. Each kit includes hardware and complete wiring and installation instructions. Basic kits are designed for panel mounting, while deluxe kits are housed in a turnkey bench-top case. |
