Key parameters
Measuring range
Single-channel multiparameter: flow, pH/ORP, conductivity/resistivity, salinity, temperature, pressure, level, DO, 4–20 mA
Accuracy
Sensor-dependent; transmitter displays calibrated engineering units per GF datasheet
Output
One 4–20 mA output standard; optional second analog, relays, batch, Modbus modules
Supply
12–32 V DC (see OEM datasheet power table)
Process connection
Panel mount (¼ DIN) or field mount enclosure versions (3-9900-1P / 3-9900-1)
Wetted parts
N/A (transmitter); sensor wetted parts separate
Fits single-channel multiparameter indication and control where you need a GF Signet 9900—flow, pH/ORP, conductivity/resistivity, pressure, level and related sensor inputs with a standard 4–20 mA output and 12–32 V DC power.
Key advantages
- Parameters — Flow, pH/ORP, conductivity/resistivity, salinity, T, pressure, level class
- Output — One 4–20 mA standard; optional second analog/relays/batch/Modbus
- Power — 12–32 V DC
- Mount — ¼ DIN panel or field enclosure versions
- Form — SmartPro-class single-channel platform
Typical applications
- Single-loop chemical dosing panels.
- Cooling-tower parameter display.
- Skid transmitter with one sensor family.
Selection guide
- Panel vs field mount
- Module options (relay/Modbus)
- Sensor electronics pairing
Common mistakes
- Expecting dual independent channels (use 9950).
- Wrong sensor electronics for DryLoc/S3L.
- Power below 12 V DC.
When to RFQ / what to tell us
- Mount, modules, sensors.
- Quantity, ship-to.
