Four-Wire, Two-Parameter Transmitter for Analytical Sensing Apps
The transmitter accepts data from two sensors and measures any combination of various parameters including but not limited to turbidity/suspended solids, nitrate, SAC (UV254), ISE, dissolved oxygen, pH/ORP, chlorine, concentration and conductivity. By using the single transmitter, users save money because only one instrument has to be purchased, installed and maintained. It also saves space, and it results in a simpler analytical sensing system. The transmitter accepts any two Memosens sensor inputs, each with true hot plug-and-play capabilities via a digital interface link. This allows users to interchange sensors at will with immediate sensor recognition. Users can quickly and easily remove and replace each sensor for calibration, diagnostic and other purposes. The transmitter is powered by 100-230Vac 50/60 Hz, 24Vac 50/60 Hz, or 24Vdc. It conforms to Type 4X (IP66/IP67) and is NRTL certified for conformance to UL standard 61010-1 for installation in appropriate environments. It also has a single alarm output, two 4-20mA analog outputs, and a backlit display. The transmitters can be upgraded to include features such as additional sensors and outputs—or communication options including Profibus, Foundation Fieldbus or Ethernet.
