CAS DataLoggers has announced that a temperature control systems manufacturer has recently installed the Squirrel SQ2040-2F16 datalogging solution across shipboard containers, railway cars, trailers, buses and trucks to monitor the performance of refrigeration diesel engines, as part of a study in alternative diesel fuel mixtures.
The test results will be applicable to a new legislation by the California Air Resources Board for the regulation of particulate matter emissions from the exhaust of the vehicle.
The Squirrel datalogger fits the requirements of the management for a handheld, cost-effective datalogging solution capable of accurately monitoring multiple parameters including voltage, resistance and temperature, offering several communication ports for easy data retrieval.
The Squirrel SQ2040-2F16 datalogger was connected with several pressure and temperature sensors to monitor the engine’s coolant temperature, exhaust gas temperature, unit pressures and system voltages at regular intervals.
The year-long emissions testing program resulted in decreased diesel PM emissions. The device recorded the test parameters with a high degree of accuracy and reliability. Its compact design allowed for convenient repositioning and use of the datalogger and enabled quick access to the transmitted data. As part of the emissions reduction initiative, the manufacturer has been awarded the CARB Level 2 Plus verification.
The Squirrel SQ2040 datalogger offers measurements of voltage, current, temperature and resistance with 0.05 percent accuracy, enabled by the 24-bit ADC converters and twin processors. The Squirreldatalogger can be mains powered or battery operated and can be easily configured using a PC or an integral interface. It offers an internal memory of 128 MB capable of storing 14 million readings.
