Innovative manual retractable fitting with safe-to-operate rotary drive
For applications in which pneumatic fittings are not essential, Knick has developed the SensoGate® WA 131M, a state-of-the-art manual sensor lock-gate fully compatible with its pneumatically controlled “ sister fittings”. This applies to rinsing chambers and process connections as well as the materials used.
Revolutionary operation
The SensoGate® WA 131 M has a manual rotary drive, which enables the fitting to be operated up to a counter pressure of 10 bars – and this in less than two turns. Regardless of how unfavorable the angle or the operating height at which the fitting is installed, the low rotary forces can easily be applied using the wrist. This is not possible with the sliding motion of conventional fittings.
Maximum process safety
The configuration of the O-rings means that there is never any connection between the drain opening of the rinsing chamber and the process, even during the inward and outward movement. For reasons of safety, the sensor can only be removed in the service position. Automatic extension protection reliably blocks the movement of the fitting and prevents extension into the process position with no sensor. Furthermore, the immersion tube is secured against twisting, which guarantees constant flow conditions for the sensor in the process.
