Mobrey M-Switch Horizontal Float Level Switch
Manufactured in 316 stainless steel throughout, the M-Switch small float level switch is available for side mounting with either a flange or 50mm/2" thread.
Comprising a small float on the wet side and a body containing a high current micro-switch on the dry side, the Mobrey M-Switch small float level switch will reliably detect liquid level to give a voltage free contact operation for alarm signalling or as part of a pump control system.
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.
Owing to the high cost of wiring, most process plants have hundreds or even thousands of discrete measurement points that are not connected to the control system. The advent of wireless communications allows process plant managers to save up to 90% of installation cost compared with wired technologies, enabling them to collect more data at central locations than has ever been possible before.
