The 4000DP is a differential pressure transmitter delivering 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 and dry gases. The transmitter ID, transmission speed and calibration data is programmed into its onboard memory using a software package which automatically recognises the type of unit connected to the PC via the USB lead. The unit is fitted with a custom-designed LCD to indicate current readings, battery life remaining and alarm conditions.
