Submersible pressure sensor type ABS MD 127

Submersible and highly accurate

MD 127 is a sewage water resistant, stainless steel encapsulated, submersible, hydrostatic level sensor of very high accuracy and over pressure capability. It is designed for level measurement in liquids like stormwater and wastewater in pump sumps. When connecting the 2-wire loop powered sensor in series with a DC power supply, the MD 127 gives a 4 to 20 mA output signal which is proportional to the level of the liquid.

Submersible Pressure Sensor Type ABS MD 127

The output signal can be connected to the mA – input of set point relays, chart recorders, indicating instruments, PLC, pump-controls, etc. The number of devices in series and the length of the cable from sensor to the devices is dependant on the supply voltage.
The ceramic sensing element can withstand very high overpressures without damage.

Pumping station control
Control systems provide functionality and data that can be used to improve the availability of pumps, pumping stations and entire collection networks. They are a simple way to reduce not only the risk of downtime and flooding, but also maintenance and energy costs. Sulzer has a full range of control systems that are as easy to use as they are sophisticated.
