Products/Services for limiting temperature
Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. Search by Specification | Learn More
Current limiting diodes (CLD) regulate current over a wide voltage range. There are several types of current limiting diodes (CLD). Examples include a current regulator diode, constant current diode, and current limit diodes. Search by Specification | Learn More
Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input. Search by Specification | Learn More
Temperature controllers accept inputs from temperature sensors or thermometers, and then output a control signal to keep the temperature at the desired level. Search by Specification | Learn More
Temperature signal conditioners accept outputs from temperature measurement devices such as resistance temperature detectors (RTDs), thermocouples, and thermistors. They then filter, amplify, and/or convert these outputs to digital signals, or to levels suitable for digitization. Search by Specification | Learn More
Limit switches are electromechanical or solid state devices that require the physical contact of an object with the switch’s actuator to make the contacts change state. Search by Specification | Learn More
Rotary limit switches use physically-actuated levers to rotate a shaft and operate the contacts in a switch, making them change state. Search by Specification | Learn More
Linear limit switches are electromechanical devices that require physical contact between a target object and switch activator to make the contacts change state. Search by Specification | Learn More
Temperature probes are used in various temperature sensing applications. Technology options include thermocouple, RTD, thermistor and solid state style probes. Search by Specification | Learn More
Thermocouple temperature probes are bimetallic probes that are used in various temperature-sensing applications. They consist of two wires, each of which is made of a different metallic element or alloy. Search by Specification | Learn More
