Compact High Pressure Liquid Level Transmitter with Digital S3L Output and PVDF/Hastelloy C Construction for Conductivity and Resistivity Monitoring
Integral Conductivity/Resistivity Sensor — K=0.1 cm⁻¹, PVDF/Hastelloy C, Digital S³L Output
The +GF+ Signet 3‑2850‑51‑40V is an integral-mount conductivity/resistivity sensor system combining 2850 smart sensor electronics with a 2840 electrode (cell constant K=0.1 cm⁻¹) in a PVDF/Hastelloy C wetted construction. Key specs: range 0–1,000 µS/cm, accuracy ±2% of reading, update <600 ms, 12–24 VDC power, Digital (S³L) output at 9600 bps, EasyCal auto-recognition, NEMA 4X/IP65, and ¾″ FNPT process connection for submersible or inline installation.
Automation Role — Where Used & Core Function
It delivers a temperature-compensated conductivity (or resistivity) signal to Signet 9900/8900 controllers or a PLC/DCS for RO/DI quality interlocks, rinse-cycle acceptance, regeneration triggers, and TDS/alarm logging. Typical use: RO permeate monitoring, DI water loops, boiler/condensate control, neutralization support, and scrubber liquor tracking in the mid-purity range. The PVDF/HC corrosion-resistant build + S³L digital link prevents analog drift over long cable runs (up to 120 m / 400 ft) while EasyCal keeps field calibration audit-friendly and fast.
