June 2005 Data Acquisition & Telemetry

SSE has developed and is offering a new low-power telemetry RTU for use in applications where power and theft of solar panels is a major problem.

SSE identified a market segment where a low-power RTU is of the utmost importance. Many applications such as reservoir monitoring, flow station monitoring and logging, tank monitoring, do not need minute by minute monitoring.

Many metros, city councils, municipalities, water-boards, electrical councils and companies distributing products to the industry need a cost-effective solution to monitor their products and plants over large distances. Not only must the unit be cost-effective to acquire, but it must also be cost-effective during the operation and running of a system.

SSE believes that it has developed exactly what the market needs:

* Eight analog inputs (12 bit resolution).

* Eight digital inputs (with or without opto isolation).

* Four Power Digital Outputs that can switch 3 A for switching of communication mediums, instrumentation and other equipment during power save mode.

* Two RS232 ports.

* A GSM modem on the micro-RTU (which can be removed if to be used in radio applications).

* If used in low-power mode, the unit switches off all peripherals on the RTU as well as selected instrumentation, if needed.

* Depending on the rate of reporting of data to a master station, the battery can last from four to five years.

* Most functions built into the bigger brother SSE-RTU-11 are included in the micro RTU.

* Can communicate using SMS, GPRS, analog radios, digital radios, RS232/485, etc.

* It also offers 'PLC' programmability.

SSE reports receiving orders for a few hundred units before the official launch of the unit

One of the orders received was from the Tshwane Metro for the monitoring and logging of more than a 100 flowmeter stations in and around Pretoria. The system will be running separately from the existing 120 SSE-RTU-10-Telemetry outstations already in use by the Metro.

This system will be running on battery on the GSM network using SMS. The unit will log the data once an hour in the RTU and then switch the PSM on once a day to report the logged data. The unit, however, can be configured in any other user application mode as needed by the client.
