    1.1 Intended Use The SensoGate WA131 is a retractable fitting for installation in boilers, tanks, and pipes. The product is used to mount a sensor for measuring process parameters. The sensor is immersed in the process medium by the SensoGate WA131.

  • Page 6: Safeguards

    The SensoGate WA131 is in the service position (SERVICE limit position). The SensoLock ring is set manually to “lock” and the SensoGate WA131 cannot be moved to the process position (PROCESS limit position). After installing the sensor, the SensoLock ring is set to “unlock”.

  • Page 48 SensoGate WA131 Weld-in sockets with an HSD (Handling Safety Design) safety function feature spe- cial grooves on the sealing surface for the process connection O-ring. These grooves prevent the O-ring from sealing if the Ingold coupling nut loosens inad- vertently when process pressure is present. A minor leak means the loosening can be detected quickly and remedied before the Ingold coupling nut comes loose from the thread completely.
