Self-diagnoses Function of Gas Detector Helps Your Plant Safety

Dec 07 2021

With the aging of the plant and the retirement of experienced and professional engineers who has been responsible for maintenance and safety management, the risk of serious accidents due to inappropriate responses caused by insufficient knowledge and experience of employees may increase.

RIKEN KIEKI’s gas detector, model SD-3 series, has self-diagnoses function by using digital signal so that promoting maintenance management of gas detector and so keeping plant safety.

Sensor degradation assessment function

The individual sensor principle characteristics are used to automatically diagnose sensor degradation (e.g., reduced zero point output and low electrolyte levels).

It avoid wasting sensors that can still be used at periodical maintenance. As a result, it reducing cost and improve “Preventive Maintenance”.

Life assessment function

Diagnoses the sensor life during calibration by predicting the sensor output reserve value based on the past calibration history.

Determined the sensor condition is used to be done when adjusting the span adjustment (“Breakdown Maintenance”). However, this function alert pre-warning so that users are able to do the “Predictive Maintenance”.

Digital signal  

SD-3 is able to use digital signal 4-20mA+HART or RS-485. Safety management would be more improved by connecting SD-3 with host system to centrally management of huge number of gas detector at the plant.
