SIL Compliant Temperature Measuring Points

From WIKA Instrument, LP

Temperature is the most measured value in process engineering, therefore, temperature is suited for the detection of hazardous conditions in plants so that corrective measures may be taken at an early stage. If there are no design or logistic measures that could be taken to prevent a hazard, the temperature measuring point itself must be designed in accordance with the standards of functional safety for process technology.

Products & Services
Resistive Temperature Devices (RTD) Elements
Resistive temperature device (RTD) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature. They are usually made of metallic elements or alloys such as copper, nickel, or nickel-iron.
Dial Thermometers
Dial thermometers are bimetal or bi-metallic, liquid or gas-filled, and vapor-tension-based. These devices display temperatures in Fahrenheit, Celsius, or both.
Thermostats and Thermal Switches
Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.
Thermowells
Thermowells are designed to accept numerous types of temperature probes. They are used to easily facilitate the repair of temperature sensing devices without interrupting the process being monitored.
Digital Thermometers
Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display.
