CDS552 CIRRUS LOOP LOGGER
1.1
Introduction
The Cirrus Loop logger is a robust, sophisticated LTE/4G GSM logger/controller with a wide range of input capabilities,
making it ideal for a large number of measurement applications.
Communication to your own server and database can be achieved via the internet or a private APN. The software running
on these servers is supplied free of charge. The Cirrus Loop Logger has been designed to allow for easy installation and
setup without the need for a complicated server infrastructure. Setup and management software (CloudWorks) is also
supplied free of charge to allow clients to manage their own networks and data. There are no monthly charges for
collecting and hosting data as the client can provide this service themselves.

Features
Uses GPRS/EDGE/LTE/4G technology. 4G has become essential as many cellular network providers around the
world will soon no longer be supporting older GPRS/3G technologies, rendering these legacy dataloggers obsolete.
This has already started happening in many countries around the world.
Bluetooth interface - setup and manual data collection can be achieved through the Bluetooth interface negating
the need for cables that invariable fail during continuous use.
Optional external power operation with battery failover.
Uses standard off-the-shelf alkaline batteries. This logger uses 3x standard D Cell alkaline batteries that can last in
excess of 5 years under normal usage. Many other loggers use lithium batteries that are expensive and difficult to
obtain. Other problems involving lithium batteries are the restrictions when shipping using airfreight. All lithium
batteries need to be shipped as hazardous cargo that is becoming increasingly difficult to achieve as many airlines
are no longer allowing these batteries on their aircraft.
2 x Pulse input ports - Pulse inputs are used on metering devices that supply a pulse output for a measured
amount of product.
Isolated 4-20mA interface. Used for any sensing device with a 4-20mA output.
