Cảm biến báo mức kiểu phao Mobrey M-Switch
Manufactured in 316 stainless steel throughout, the M-Switch is available for side mounting with either a flange or 2-in. thread. Comprising a small float on the wetside and a body containing a micro-switch on the dryside, the Mobrey M-Switch reliably detects liquid level to give a voltage-free contact operation for alarm signalling or as part of a pump control system. Operating principle One permanent magnet forms part of a float assembly which rises and falls with changing liquid level. A second permanent magnet is positioned within the switch so that the adjacent poles of the two magnets repel each other through the nonmagnetic wall of the switch body. A change of liquid level which moves the float through its permissible travel will cause the float magnet to move and repel the switch magnet to operate the micro-switch contacts. Wireless option All the models in the Mobrey range of float switches are available for use with the Rosemount 702 wireless discrete transmitter, allowing plant managers to cost-effectively access valuable data about the performance and safety of their plant.
