Emerson Rosemount 1067 temperature sensor

Rosemount 1067 Compact Temperature Sensor

The Rosemount 1067 compact temperature sensor is a DIN-style sensor available in a variety of industry-standard sensing technologies, including resistance temperature detector (RTD) and thermocouples. For optimized efficiency and increased measurement reliability, this sensor provides single and dual element configurations. The RTD includes a calibration option of Class A or B accuracy or a calibration schedule option with Callendar-Van Dusen constants.-18

Complete Rosemount 1067 Sensor Model Numbers

The Rosemount 1067 series follows an ordering code structure where each complete model number encodes specific configuration options:

Additional complete Rosemount 1067 configurations include:

1067A1B0N0 – Single RTD, Class A accuracy, 3 mm diameter for faster response

1067C1C0N0 – Single thermocouple type E, ungrounded, extended length configuration

1067F2J0N0 – Dual thermocouple type R (platinum/rhodium), high-temperature service

1067G1K0N0 – Single thermocouple type N, PTFE insulation, flying leads, 3 mm diameter

Each model number encodes sensor type (RTD or thermocouple), element count (single or dual), lead wire termination style (terminal block or flying leads), accuracy class, diameter (standard 6 mm or compact 3 mm), and optional approvals.

Full Technical Specifications

The compact 3 mm diameter design of the Rosemount 1067 produces quicker response times compared to standard 6 mm sensors. The 3 mm diameter sensor is particularly advantageous in applications requiring rapid detection of process temperature changes, such as reactor temperature control, heat exchanger optimization, and safety-critical monitoring.-18

Integrated Annubar + 1067 System Applications

Combining Annubar flow measurement with Rosemount 1067 compact temperature sensors creates comprehensive monitoring and protection systems across numerous industries:

Fully Compensated Mass Flow Measurement

When a Rosemount 1067 compact temperature sensor is integrated with a Rosemount 3051SFA Annubar flow meter, the system delivers fully compensated mass flow measurements. The 1067 provides process temperature data, while the pressure transmitter measures static pressure and differential pressure. The flow computer then calculates mass flow using real-time density compensation — essential for natural gas measurement, steam energy monitoring, and custody transfer applications.

High-Temperature Steam Energy Monitoring

For steam applications exceeding 850°F, the Rosemount 585 Annubar Primary Element (capable of 1500°F operation) combined with the Rosemount 1067 thermocouple configuration — such as 1067C1E0N0 with type K thermocouple — provides complete energy flow measurement. The 1067‘s ungrounded junction configuration eliminates ground loop interference, while the sensor’s 1,000 MΩ minimum insulation resistance ensures signal integrity in high-noise environments.-18

OEM Skid Fabrication

OEM skid builders benefit from the compact size of both devices. The Rosemount 1067 with 3 mm diameter — model 1067A1B0N0 — and the Rosemount 2051CFA Annubar flow meter (for line sizes 2 to 12 inches) together form a compact, factory-calibrated measurement skid requiring minimal panel space. The 1067‘s DIN-style sensor connection head allows for quick mounting and replacement during skid assembly.-18

Hydrocarbon Processing

In refinery and petrochemical applications, the Rosemount 1067 RTD configuration — such as 1067A1A0N0 with Class B accuracy — provides stable, linear temperature measurement over extended periods. The RTD’s high linearity and stability within its measurement temperature range make it ideal for long-term process monitoring where calibration drift cannot be tolerated. When combined with a Rosemount 485 Annubar Primary Element, the system delivers accurate volumetric and mass flow measurement for crude oil, refined products, and chemical feedstocks.

Installation Considerations

Annubar Installation

Orientation: Liquid applications require sensor positioned between 15° to 45° from vertical down; gas applications require sensor on upper half of pipe, at least 45° above horizontal line; steam applications follow specific guidelines depending on horizontal or vertical pipe configuration.-32

Straight Run Requirements: Minimum 8–30 upstream pipe diameters and 4 downstream pipe diameters depending on upstream disturbance type (pipe bends, elbows, reducers, expanders, or valves).

Alignment Tolerance: Maximum misalignment ±3° from specified orientation; flow direction arrow on sensor tag must point in flow direction.

Rosemount 1067 Installation

Thermowell Selection: The Rosemount 1067 compact temperature sensor must be installed in an appropriate thermowell for process pressure containment. Emerson provides thermowells in various materials, types, and lengths for most industrial applications, with standard materials including 316L and 304L stainless steel as well as other materials for corrosive environments.-9

Insertion Length: The 1067 sensor should be inserted to the full depth of the thermowell bore for optimal thermal contact and measurement accuracy.

Lead Wire Termination: The Rosemount 1067 offers both flying leads (termination code 0) and terminal block options. For flying lead configurations, lead wires are color-coded per industry standards (red/white for RTD; red/white/yellow for thermocouples).-10

Hazardous Locations: If an I.S. approved Rosemount 1067 sensor is ordered with a housing and transmitter, the transmitter may have a different I.S. approval rating. Installation must comply with the most restrictive requirements of either component.-50

No User Calibration Required: The Rosemount 1067 is factory-calibrated per IEC 751 and IEC 60584 standards, requiring no user calibration upon installation.
