The BARTON 202E and 242E Chart Recorders are rugged industrial circular chart recorders engineered for accurate measurement and continuous recording of pressure, differential pressure, temperature, and flow variables in oil & gas, petrochemical, pipeline, and industrial process applications.

The 202E and 242E recorders are recognized worldwide for reliable field performance, high accuracy, and durable construction in severe operating environments. These recorders are widely used in gas transmission systems, production facilities, custody transfer metering, and process monitoring applications.

General Specifications

The 202E and 242E utilize stainless steel recording mechanisms and precision sensing elements for long-term durability and reliable measurement performance.

Model Overview

The 202E is commonly used in gas transmission and production measurement applications because of its accurate differential pressure recording capability under varying flow conditions.

The 242E is designed for pressure and temperature recording service and supports multiple pen combinations for simultaneous monitoring.

Key Features

• Rugged industrial die-cast aluminum enclosure

• High-accuracy circular chart recording

• Available in single to four-pen configurations

• Differential pressure, pressure, and temperature measurement capability

• Stainless steel recording mechanism for long service life

• Battery-driven or spring-wound chart drive options

• Corrosion-resistant components for harsh environments

• Over-range protection and pulsation dampening on DP models

• Easy chart replacement and calibration adjustment

• Suitable for severe oil & gas field applications

The differential pressure models use Barton rupture-proof bellows DPUs with built-in over-range protection.

Typical Applications

• Natural gas transmission systems

• Custody transfer metering

• Pipeline flow monitoring

• Wellhead production systems

• Refinery process monitoring

• Petrochemical plants

• Compressor stations

• Pressure and temperature logging

• Industrial utility monitoring

Operating Principle

The Barton 202E and 242E recorders use mechanical sensing elements such as helical pressure elements, bourdon tubes, thermal bulb systems, and differential pressure units to convert process variables into mechanical motion. This motion drives precision pen assemblies that continuously record process data onto rotating circular charts.

The chart drive rotates the chart at a fixed speed while the pen mechanism records process variations over time, creating a permanent historical operating record.

Advantages

• Proven industry-standard chart recording technology

• Reliable operation in remote locations

• No external power required for spring-driven models

• High durability for field service environments

• Easy maintenance and calibration

• Long-term mechanical reliability

• Accurate permanent process documentation

• Wide availability of charts and spare parts
