+GF+ 3-9950-1 - Dual-Sensor-Acquire/Derived-Logic-Control - 1/4 DIN DC Powered LCD Dual Channel Water Quality Transmitter
The 3‑9950‑1 is a field-mount dual-channel SmartPro® transmitter (12-32 VDC) with 2 × isolated 4-20 mA outputs, supporting flow, pH/ORP, conductivity/resistivity, pressure, level, and dissolved oxygen measurements via S³L / frequency / 8058 iGo® technology. Features NEMA 4X rating and USB upgrade capability.
This versatile transmitter accommodates two same or different Signet sensors on a single unit. Advanced derived functions (Sum/Difference/Ratio) and sophisticated Boolean relay logic enable control of RO/DI, chemical dosing, neutralization, scrubber, and batch processes without requiring a separate PLC. Scalable via Relay/Modbus/Condition modules.
