rl5000 differential pressure

New from Hanwell is the rl5000 dp radiotelemetry transmitter, designed for use withthe Radiolog 8 environmental monitoringsystem. The units are in IP65-rated cases andare suitable for use in tough environments.

Utilising an integral temperature compensated pressure sensor the rl5000 differential pressure transmitter delivers exceptional performance. The sensor utilises a silicon, micro machined, stress concentration enhanced structure to provide a very linear output to the measured pressure. The ports are designed with matched dead volumes. This series is intended for use with non-corrosive, nonionic working fluids such as clean dry air, dry gases and the like.

The media wetted materials are the silicon diaphragm, glass filled nylon, RTV and alumina ceramic. The transmitter ID, transmission speed and calibration data is programmed into its onboard memory using Radiolog 8, a software package which automatically recognises the type of unit connected to the PC via the USB lead.

Fitted with a custom-designed LCD to indicate current readings, battery life remaining and alarm conditions. There is an instantaneous display update button located on the front panel. Pressure connections are made via quick release Lemo pressure connectors, which avoid damage to the pressure sensor when disconnecting for calibration.

The transmitter is typically powered by a 7.5V 2700mAh battery pack, which can be fitted by the user. The battery life will be dependant on the transmission speed. Larger battery packs are available, local power input is also an option. An indicator on the LCD will warn when the battery is low, and the transmitter maintains a record of when the battery has been changed. The rl-5000 range has been designed to comply with the RoHS and WEEE EU directives, and carries the CE mark.
