Introduction

The NC 8000 is designed for level measurement in industries such as food, pharmaceuticals, and chemicals.
It functions in liquids, bulk solids, and slurries, even in challenging environments.
Features include corrosion-resistant construction, adjustable range, and proven technology.

Technical Data

Dimensions: Available in rod and rope versions with threaded and flanged connections.
Electrical Data: Operates on 12-30 V DC, with a 4-20 mA current loop signal.
Mechanical Data: Constructed with stainless steel and PFA, suitable for various process connections.
Operating Conditions: Pressure range from -1 to 35 bar, temperature range from -40 to 200°C.

Approvals

Certified for general purpose, dust ignition proof, flame proof, and marine applications.
Complies with CE, UKEX, CSA, FM, and other international standards.

Mounting and Installation

Installation should comply with local regulations and be performed by qualified personnel.
Ensure materials are compatible with the specific environment.

Operation and Use in Hazardous Locations

Includes safety barriers for hazardous areas and diagnostics for system monitoring.

Probe Modifications and Disposal

Rope probes can be shortened as needed.
Follow proper disposal procedures for electronic equipment.

Specifications and Safety Precautions

Ensure chemical compatibility of materials before installation.
Select appropriate bolting and gasket materials suitable for service conditions.
Follow grounding procedures to prevent electrostatic shock.
Ensure matching threads before inserting the instrument to avoid damage.
Cable entry devices must withstand temperatures from -40°C to 10 K above max ambient temperature.

Pressure Applications

Do not disassemble connections under pressure.
Use PTFE tape or appropriate sealing compounds for pressure applications.
NC 8000 units comply with ASME and European Pressure Equipment Directive standards.

Rope Tensile Strength

Do not exceed a tensile strength of 1900 kg/4188 lbs.
Ensure the load capacity of the silo/tank roof can withstand the force on the rope.

Handling and Mounting

Handle units with rods longer than 2 m carefully to prevent damage.
Support the NC 8000 at specified points when lifting from a horizontal position.
The rope version is designed for top mounting and should be used according to the material's conductivity.

Electrical Installation

Power supply: 12 to 30 V DC, 2-wire current loop 4-20mA.
Use shielded cables for stable measurement.
Follow specific wiring instructions for hazardous locations.

Operation and User Interface

The user interface includes an LCD, rotary switch, and push-buttons.
Menu positions allow for setting range values, fault protection, and diagnostics.
Damping values can be adjusted to alter the delay in measurement response.

Maintenance

NC 8000 requires no regular maintenance.
Repairs should be conducted by qualified personnel using manufacturer-provided components.

Recommissioning

Recommission the NC 8000 when replacing transmitters or probes, following the start-up procedure.

Overview
The document provides technical information and instructions for the NivoCapa® NC 8000 continuous level measuring system, focusing on its use in hazardous locations. It includes specifications, procedures, standards, and recommendations for installation, operation, and maintenance.

Specifications
The NC 8000 system is designed for continuous level measurement and is suitable for use in hazardous environments as per ATEX Directive 2014_34_EU and INMETRO standards. It is not assessed as a safety-related device. The equipment is marked with specific codes indicating its compliance with ATEX and UKEX certifications.

Procedures
The document outlines the procedure for setting the Upper Range Value (URV) for level measurement. It includes steps for adjusting the rotary switch and calculating the URV based on actual measurements. The best results are achieved using the highest possible actual level.

Installation and Maintenance
Installation and inspection must be performed by trained personnel following applicable codes of practice. The document emphasizes the importance of turning off power before servicing and provides guidelines for handling process pressure and material during removal.

Hazardous Location Use
The document details the permitted zones for installation, marking requirements, and specific conditions of use in hazardous locations. It includes information on electrostatic charge prevention, flameproof joints, and temperature ranges.

Warnings and Precautions
Users must ensure the equipment is not exposed to conditions causing electrostatic charge buildup. The document provides warnings for installation, including cable entry devices and blanking elements, and emphasizes the need for certified components.

Temperature and Pressure Considerations
The document specifies ambient and process temperature ranges, maximum surface temperatures, and temperature classes. It highlights the limitations of ATEX approvals concerning atmospheric pressure and provides guidance for assessing deviating pressure conditions.

Probe Modifications and Disposal
Instructions for shortening the rope version of the probe are provided, along with disposal guidelines. The document advises on the use of appropriate tools and techniques to ensure proper assembly and recycling of materials.
