Detecting leaks of safety valves with Sushi Sensor
Monitoring the temperature of equipment enables
early detection of failures to avoid unscheduled
operation shut-down.
•
To solve this problem, we focused on the fact that the temperature of
the output of the safety valve falls rapidly when seat leakage occurs.
•
The temperatures at the inlet and outlet of a safety valve are measured
by wireless temperature sensors to monitor the temperature difference.
•
Those safety valves deployed across a plant can be monitored,
because long-distance communication can be available by using
LoRaWAN® technology allowing inflexible installation in inaccessible
location.
•
Sushi Sensor is a wireless solution for the IIoT, monitoring equipment
conditions continuously and automatically acquiring condition data of
equipment.
•
Safety valves are mounted for relieving the pressure in case of a
pressure rise in equipment or piping. Because of the internal
environment, a slight amount of seat leakage may occur that requires
operation shut-down and maintenance. Since safety valves cannot be
visually inspected during operation, customers want to monitor them
remotely without equipment shut-down.
