Hanwell 4000 Sensors

Hanwell 4000T data loggers & radio loggers

Temperature ranges from -200C up to +110C and in between (depending on application).

The 4000T series of temperature data loggers and radio transmitters units are well established as the most flexible units on the market today. Each unit has been designed to be compatible with a wide range of temperature probes to provide accurate and reliable measurement specifically selected for the user’s requirements.

Additionally, depending on the format required by the user, temperature data can either be downloaded directly to a local PC using a USB cable or wirelessly transmitted directly to a local PC for automatic and immediate notification and analysis. Most wireless devices include the logging facility to guarantee against data loss in the event of radio communication loss.

Hanwell SR2

The SR2 is the second generation of the Hanwell Smart Receiver. It is a network enabled receiver, designed for collecting environmental monitoring data from multiple points within a site, or across multiple sites. In addition, it can be upgraded to a transceiver which both receives and retransmits the data. It uses standard TCP/IP communications protocols for speedy data handling. The network traffic generated is very low and data is automatically sorted and filed. See the diagram overleaf for some potential ways of using the SR2, or contact Hanwell to discuss your site specific requirements.

In addition to receiving data from the ml2000 and ml4000 ranges of sensors, the unit can also read hard-wired sensors and, optionally, be fitted with up to eight onboard probes. Each SR2 can handle data from up to 253 sensors, and up to 16 SR2s can be run on a single system bringing it to a total of 4048 sensors. The SR2 supports Hanwell’s standard and extended transmission data formats.

The SR2 logs all received data in its on-board 512kb memory. The Radiolog software continually interrogates the SR2 for the most recent data, and downloads the data according to user-defined logging periods to the server or operating PC. Software users can view live and historic data, produce out of spec and summary reports and set alarms on both the data levels and the rate of change.
