The Problem

A renewable energy company requires a weather station to provide meteorological data to their proprietary SCADA system at Solar Power Project Sites in Ontario, Canada.

System Requirements

The renewable energy company offers performance guarantees based on site analysis.  Therefore, monitoring weather conditions is vital to optimising performance.

Columbia Weather Systems (CWS) were able to offer a turnkey solar power solution incorporating Acromag 801T-1500-C Universal Temperature Transmitter

  1. The Weather Station consists of an Orion Sensor Module, panel temperature sensor and two solar radiation sensors (One at plane of array and another on a tracker).
  2. System is connected through the CWS Weather MicroServer
  3. Weather Station uses an Acromag 801T-1500-C Amplifier to amplify the solar sensor output to higher voltages suitable to the MicroServer’s inputs and applies individual sensors’ sensitivities
  4. The Acromag Temperature Transmitter also contains a limit alarm. It includes a programmable relay control.  As this is used to turn on and off sensor heaters to minimise the effect of dew and ice.

How did Acromag solve the problem?

According to Joe Brotherton, the manager of the technical services team for Swinerton Renewable Energy, the CWS product incorporating the Acromag Temperature Transmitter was a success because “We like the price point, always get a response, and it integrates easily into our SCADA system”.
