DUAL/TRIPLE DP INDICATOR WITH ETHERNET PORT / MODBUS TCP

DPG211 ETH is a state-of-the-art Clean Room Monitor with a datalogging option. It has 3 differential pressure sensors which allow the measurements to be made at three independent sets of locations (reference and measure). It uses a 32-bit microprocessor to incorporate a host of useful features. For one, it has a large memory that allows the measurements records to be saved in csv file format for 30 previous days - about 45000 records with 1 record per minute. Optionally, it can be supplied with a memory for records up to 5 years - about 550000 records. Each record has a date and time stamp from the high-accuracy RTC working in standalone or synchronised (with master) mode.

   The instantaneous (live) data is accessed using MODBUS TCP, which allows the master to read upto 254 instruments in one second or less. The logged data is in CSV (comma-separated values) format which can be downloaded by the master using FTP (File Transfer Protocol) which also allows a month’s data to be downloaded in a couple of seconds by a SCADA or other master. Both MODBUS TCP and FTP are open standard protocols. This means that the instrument can be used by any system integrator with any SCADA, PLC, DDC or DCS, HMI. No special software is required from Radix.This means that the customer is not locked in to any given instrument vendor, both at the time of purchase as well as for future expansions. Further, DPG211 ETH can also be supplied with a multi-master option, which allows the live as well as logged data to be simultaneously accessed by multiple masters, eg DDC, SCADAor DCS. All these features make DPG211 ETH easily the most powerful datalogging Clean Room Monitor available.
