Chart recorders have long been used at manufacturing plants to keep records of process factors such as pressure, flow, humidity and temperature. In laboratories, chart recorders have been used to keep graphic records of scientific data compiled through testing and diagnostics. Today, as the technology competes with data loggers, traditional chart recorders are still the preferred option for uses in remote, powerless settings and within working arsenals that lack complex computing systems.
General Tech Services have partnered with Barton, Cameron to provide the best Chart recorders in the industry to our customers worldwide. BARTON provides a variety range of chart recorders that are renowned for accuracy, reliability measurement and recording of pressure, differential pressure (DP), and temperature. Their fully mechanical operation is independent of external utilities that facilitates a low installation cost or portability.
BARTON Chart Recorders 202N
The 202N is a 12 “chart recorder intended to measure flow, static pressure, and temperature in applications for gas. The 202N reaches all NACE criteria for H2S settings up to 2000 psi (138 bar) BARTON’s M199 NACE DPU actuates the 202N. Static pressure readings are given by helical-type components of the accuracy patient K-model. The Barton Model 202N Differential Pressure Recorder tests and registers scheme operating parameters including gas and liquid flow rate, ship liquid concentration, and other process factors that can be evaluated using differential stress and static pressure techniques.
BARTON Chart Recorders 242E
The Barton Model 242E Temperature and Pressure Recorder is a flexible and tough tool intended for overall temperature and pressure purposes. It registers the temperature and pressure measured on a graph of 12 inches in diameter. Up to four elements can be used in any mixture to function up to four-person tracking pads. The static pressure scheme comprises a helical bourdon tube linked to the piping of the structure. The static pressure component monitors the static pressure in a tube scheme. Elements are accessible for evaluating pressure varying from 30 in. From void (mercury) to 30,000 psi. The thermal systems are a spiral bourdon tube, a capillary, and a bulb. All sections are produced from stainless steel. The bulb is equipped with a bendable expansion and the capillary is shielded by the armor of stainless steel.
Model 242E (Temperature/Pressure) The 242E is a 12” chart recorder with pressure and/or temperature elements. Configurations can be any combination of pressure and temperature elements, up to 4 pens.
Calibration, inspection, cleaning, and/or repair of Chart recorders of any brand is available at General tech services LLC.

The standard temperature system in all Barton Chart Recorders comprises a factory sealed sensing system that uses a non-toxic fill fluid that converts temperature to mechanical motion. Each temperature recording pen includes a built-in correction for ambient temperature influences. The sensing system is offered in various lengths to support the remote mounting of the recorder.
Specifications Differential Pressure:
• 0 to 10 inches of water (2.5 kPa) through 0-100 PSI (0.69 MPa) differential (higher ranges with model 224 DPU)
• Safe working pressure: Up to 6000 PSI (41.3 MPa) • Optional alloys; Inconel bellows, Stainless steel bodies
• 0 to 25 PSI (0.17 MPa) through 0 to 30,000 PSI (207 MPa), maybe calibrated as a gauge or absolute pressure
• 0 to 500F (-18 to 260 C) in 5 ranges
• Cameron’s BARTON chart recorders are the industry standard for accurate, reliable measurement and recording of pressure, differential pressure, and temperature in a variety of applications.
Differential pressure models, like the 202E and 202N, utilize the BARTON rupture-proof bellows DPU as the actuating unit, featuring over-range protection and pulsation dampening. Chart Drive – Chart drives are available in battery and spring-wound versions with a wide variety of rotation speeds. All chart drives have a simple, positive chart lock hub and are interchangeable. NUFLO Charts – The charts are made from wood-free paper – a special, low-shrinkage, high-quality product that eliminates eccentric and elliptical errors. Charts are shrink-wrapped to help maintain the factory default size until the package is opened by the user. Once a box of charts is opened, it can be stored in the supplied, plastic, resealable storage bag.
How to Select a Chart Recorder?
Many applications are suitable and require the installation of chart recorders. Before choosing one, make sure you consider the following questions:
• How many inputs need to be recorded?
• What types of inputs need to be recorded?
• Do different input types need to be recorded in the same unit?
• What type of recording is required?
• Multiplex scanning (what minimum scan cycle is required?)
• Is a communication interface required?
• Is the recorder to be bench style or panel mounting?
• What type of instrument power is available?
• Is log-type recording desirable instead of/in addition to trend recording?
• Is color differentiation available for trend lines?
• Is message printing required?
• Is the recorder to perform alarm functions?
• How many setpoints per channel?
• What types of alarms: threshold, rate delta?
• Are physical relay contacts available for external alarm output?
Chart Recorder Vs Data Logger
Chart recorders allow users to view recorded data quickly and easily along with sheets of paper. The marking components of a chart recorder are easy to replace and the charts are available in various sizes. Basically, a chart recorder is ideal for any B2B application in which physical paper is necessary for the documentation of process studies. However, chart recorders limit studies by the length of the paper feed. The portability of a chart recorder is inverse to the data resolution, which is better in larger units.
The pros and cons of a chart recorder can be summarized as follows:
• Instantly viewable data recordings.
• Easy-to-replace charts and makers.
• Data recorded onto physical paper.
• A range of chart sizes, such as 4″, 6″ and 8″.
• Paper and marking devices must be refilled.
• Recording time restricted to the given length of a chart roll.
• Data resolution limited in smaller units.
• Less portability with larger, high-resolution units.
Data Loggers Data loggers have supplanted chart recorders in most of today’s B2B and laboratory applications. A data logger is a device equipped with digital sensors that read the conditions of any given environment put to study. The data is held in the unit’s digital memory and then transferred to a computer system for storage and subsequent study. As such, data loggers require a more modernized computer arsenal. The pros and cons of a data logger can be summarized as follows:
• Compact design can fit into almost any working environment.
• Recorded data can be viewed at any level of resolution on a computer system.
• Data can be imported into software programs and studied in different formats.
• Data are available for instant viewing on display devices.
• Does not require paper charts or marking devices.
• Data must be transferred from the logger memory to a computer via USB or Ethernet cable.
• Requires working knowledge of computers. In the industrial sector, chart recorders allow manufacturers to capture vital info about the environmental factors of working processes. With trend recordings on paper logs or digital files, a company can determine how to most efficiently generate and assemble products and yield the highest levels of productivity.
Chart recorders are also important in B2B applications that take place between companies on a local, national and international scale. All things considered, chart recorders are complex pieces of equipment that sometimes require servicing and repair work. The next time your company needs chart recorder repairs, look no further than General Tech Services LLC.
