Key parameters
Measuring range
Single-channel liquid analysis: pH/ORP, contacting/toroidal conductivity, dissolved oxygen, chlorine, ozone (sensor-dependent)
Accuracy
Per connected Rosemount Analytical sensor and measurement type (see 1066 PDS/RM)
Output
Loop-powered 4–20 mA with HART or FOUNDATION Fieldbus digital communications
Supply
Minimum 12.7 Vdc at transmitter; HART external load 250 Ω typical
Protection
Type 4X / IP66 polycarbonate enclosure
Ambient temperature
−4 to 131 °F (−20 to 65 °C); RH 5–95% non-condensing
Fits loop-powered single-channel liquid analysis where you need a Rosemount 1066 measuring pH/ORP, conductivity, DO, chlorine or ozone with 4–20 mA HART or FOUNDATION Fieldbus.
Key advantages
- Type — Two-wire single-channel liquid analysis transmitter
- Measurements — pH/ORP, conductivity, DO, chlorine, ozone (board-dependent)
- Outputs — 4–20 mA with HART or FOUNDATION Fieldbus
- Power — Loop-powered
- UI — Local operator interface for configure/calibrate
Typical applications
- Single-loop pH or DO transmit.
- HART liquid-analysis loops.
- FF segment analytical points.
Selection guide
- Measurement board — pH vs DO vs Cl2
- Protocol — HART vs FF
- Sensor family — Compatible Rosemount sensors
- Hazardous approvals — If required
Common mistakes
- Expecting dual-channel (see 1056).
- Wrong board for sensor type.
- Missing HART load resistor.
When to RFQ / what to tell us
- Measurement type, protocol, approvals.
- Quantity and ship-to.
