Dataloggers:

rtm40 GSM datalogger

The rtm40 series GSM dataloggers combine proven Hanwell data logging technology with state of the art GPRS data communications. The advantage of GPRS is that reliable communications can be established in areas where conventional land lines are not available or are unreliable. GPRS is the technology of choice, for minimum running costs, especially when large numbers of recorders are envisaged.

Many thousands of sensors can be supported by the GPRS version of Hanwell's market leading Radiolog software. This package provides totally automated communications with fully integrated, logging, alarming and reporting facilities. Multiple concurrent users are supported in networked environments.

Housed in a ruggedised polycarbonate housing, the rtm40 series loggers have been designed with the toughest of environments in mind. A major problem with using GSM/GPRS technologies outside is condensation damage to the radio module and SIM card. The rtm40 has a built-in condensation protection system, allowing the unit to be used over the temperature range -30 degrees C to + 45 degrees C.

The rtm40 series dataloggers are ideal for remote applications in transportation, cold storage, bulk storage, water and waste treatment, and other process industries. The rtm40 is suitable for temperature, humidity, flow, level, pressure and many other monitoring applications.

Key Features

• Logging continues independently in the absence of external power
  
• External power fail detect and alarm via GPRS
  
• Hi and low alarms on all channels
  Compact data encoding to minimise ongoing costs
  Local download capability for field use and diagnostics
  
• Field calibratable where return to base calibration would be impractical or would result in unacceptable downtime
  
• Local onboard display
  
• GPRS support to allow integrated tracking
  
• Housing deliberately designed to be inconspicuous. To reduce vulnerability when located in unmanned locations
  
• Optional RF interface for applications such as trailer to tractor.
