RTD, Thermocouple, Thermistor Sensors & More

RTD & Thermocouple Plugs, Jacks, & Accessories

When using industrial temperature sensors you have to consider how you will connect the sensor to your instrumentation and how you will mount the sensor into your process. The products found in this section and suggestions from our thermal advisors will help do the job right!

Thermocouple, RTD, Thermistor and Hook-Up Wire

Some things to consider regarding the wire to use with your temperature sensor. If you are using a Resistance Sensor you can use a copper wire, but if you have a Thermocouple you must know:

1. What thermocouple "type" you are using?
2. What temperature must the insulation withstand?
3. What gauge of wire do I need?
4. How far can I run the wire?

RTD Resistance Temperature Sensors

An RTD (Resistance Temperature Detector) is a variable resistor that will change its electrical resistance in direct proportion to changes in temperature in a precise, repeatable and nearly linear manner. To sum this up.....The RTD is one of the most precise, repeatable sensors on the market. However, consultation with one of our experts is always welcomed before purchasing this style of sensor. Slight variables in proper selection, design, and connection can cause unwanted errors. Call us on 1-800-847-8367.

Thermocouple Temperature Sensors

A temperature sensor is a device, typically, a thermocouple or RTD, that provides for temperature measurement through an electrical signal. A thermocouple (T/C) is made from two dissimilar metals that generate electrical voltage in direct proportion to changes in temperature.

Custom & Multi-Point Thermocouples

Multipoint thermocouples measure the temperature at different points along its length. These sensors are frequently used in chemical and petrochemical industries because they provide an excellent temperature profile for chemical reactors, catalytic crackers, and fractionation towers, and fluidized bed catalyst tank. The number of junctions possible in a sheath diameter is dependent on whether they are ungrounded or grounded hot junctions. Please refer to the table below to find out how many junctions you can have.

Thermocouple Hardware Accessories

Transmitters

These are devices that change the signal from the temperature sensor into a 4~20mA current signal, enabling the signal to be transmitted over a long distance over copper electrical wires.

Thermowells

Thermowells are tubular fittings used to protect temperature sensors installed in industrial processes. A thermowell consists of a tube closed at one end and mounted in the process stream.
