Engine Monitoring System Controller


The EMS PRO is a flexible all-in-one customizable unit that meets the needs of engine-driven pumping equipment applications. The EMS PRO is a dedicated microprocessor-based, single engine controller. It offers field-adjustable operating parameters that can be changed without the need for a computer. It is also able to support both mechanical and J1939 electronic engines.


The EMS PRO has selectable auto start/stop features with several throttling options. The auto start/stop options (Single Contact, Floats, Momentary, Transducer and Clock) are available at the touch of a button. The Transducer start/stop option includes three settings; pressure, level and temperature. In addition, there are many performance-enhancing features, all of which are available through an operator interface that is easy to learn and use. The EMS PRO is ideal for use with a remote modem or in a SCADA system offering Modbus RTU protocol on either the RS232 or RS485 port.


The EMS PRO has the ability to withstand a wide ambient temperature range and comes standard in a NEMA 4 rated enclosure secured by four rubber shock mounts. Inside is a backlit graphical display visible day or night and under all kinds of conditions.
