SAFETY IN SENSORS
CERTIFIED SENSORS FOR MAXIMUM SAFETY
To reduce the probability of an undetected sensor error, plausibility checks can be performed either in the sensor or in the system control. This enables the use of sensors in safety devices. TWK offers a range of sensors certified in accordance with DIN EIN 13849 (PLd) or IEC 61508 (SIL2) for plausibility checks within the sensor. Alternatively, redundant sensors are typically used if the user prefers to delegate this task to the control system.
TWK has appropriate sensors in its program for this situation. In potentially explosive atmospheres, sensor heating must remain below the ignition temperature. Therefore, our ATEX (ATmosphères EXplosibles) sensors are certified in accordance with DIN EN IEC 60079 and designed to prevent the ignition temperature from being exceeded, even in the event of a short circuit. Safety in explosion protection is increased by a combination of functional safety and ATEX.
