LR-Cal Pressure Calibrators and Test Pumps

Product catalog summary
Introduction
This document provides an overview of LEITENBERGER's pressure calibration equipment, highlighting the quality and expertise of German-made products. It includes detailed specifications, procedures, and recommendations for pressure calibration.
Contents Overview
The document is organized into sections covering various calibration instruments such as portable systems, pressure controllers, deadweight testers, and pressure comparison pumps. Each section includes model overviews, functional principles, and application recommendations.
Pressure Calibration Recommendations
Effective pressure calibration involves calibrating the entire measurement chain, considering ambient conditions, and using a reference instrument with accuracy four times better than the unit under test. Calibration sequences vary based on the accuracy class of the unit under test.
Calibration Instruments
  • Pressure Controllers: Models LCC 100 and LCC 200 are noted for generating and measuring small pressures and vacuums without additional accessories, suitable for high precision measurements.
  • Deadweight Testers: These primary standards offer high accuracy and long-term stability, operating mechanically without a power supply.
Model Overviews
Detailed model overviews are provided for various calibration devices, including pneumatic and hydraulic pressure ranges for deadweight testers, pressure comparison pumps, and pressure calibrators with accuracy specifications.
Functional Principles
The functional principle of deadweight testers is based on the physical principle of pressure as a quotient of force and area, ensuring high measurement accuracy and stability.
Conclusion
LEITENBERGER's calibration equipment is designed for precision and reliability, with recommendations for regular recalibration to maintain accuracy. The importance of using high-quality materials and adhering to calibration standards is emphasized.
Specifications
Deadweight testers are precision instruments for calibrating pressure measuring devices, constructed with high-quality materials like Tungsten Carbide for minimal pressure and thermal expansion. The recommended recalibration interval is five years.
Procedures
Devices require an external pressure supply for models over 10 bar and include a finely adjustable spindle pump for precise regulation. Equilibrium is achieved when pressure and mass are balanced.
Standards and Recommendations
Accuracy is characterized by measurement uncertainty, with a traceable factory calibration certificate included. Optional DKD/DAkkS certification is available, with accuracy specified up to ±0.008% of the measured value.
Design and Features
The piston and cylinder are protected in a stainless steel housing with integrated overpressure protection. The design ensures excellent operating characteristics, including long free-rotation time and low sink rates.
Accessories and Additional Information
Available accessories include trim-mass sets, threaded adapters, medium separators, and special oils for hydraulic models. Free Excel sheets for correction calculations are available for download.
LR-Cal Pressure Comparison Pumps and Calibrators
Detailed specifications and features of LR-Cal pressure comparison pumps and calibrators are provided, focusing on both pneumatic and hydraulic systems.
Specifications
The LR-Cal LPP 60-T is a pneumatic pressure comparison pump capable of generating pressures up to 60 bar and vacuum up to -0.95 bar, featuring a fine volume adjustment valve and a pressure relief valve.
Hydraulic Models
Several hydraulic pressure comparison pumps are listed, with pressure ranges from 1000 to 7000 bar, using oil or special oil as the operating fluid.
Pressure Calibrators
The LR-Cal LPC 300 is a documenting process and pressure calibrator with a full numeric keypad and cursor block, supporting multiple pressure ranges and features such as measurement of current and voltage.
Optional Accessories
Various optional accessories are available, including tools for volume adjustment, threaded adapter sets, and transit cases for portability.
Key Features
The document highlights ease of use, intuitive menu navigation, and the ability to create calibration procedures with data storage.
LR-Cal Pressure Calibrators
Specifications and functionalities of various LR-Cal pressure calibrators, including the LPC 300 and LPC 200, are covered, along with their features and calibration procedures.
Calibration Procedures
Calibration procedures can be pre-defined with details such as ID numbers, pressure ranges, and accuracy classes, with data transferable to a PC using LPC-Cal software.
Data Management
The LPC-Cal software allows for online calibration and certificate creation, requiring specific system requirements.
Additional Models
Additional models such as the TLDMM Series, LDM 70 Series, and LPP-MANO Series are described, each with unique features and applications.
Recommendations
For handheld manometers, specific pressure test pumps are recommended for calibration purposes.
LR-Cal PC4 Pressure Calibrator
Detailed information about the LR-Cal PC4 pressure calibrator is provided, designed for verifying and calibrating pressure sensors, gauges, and switches for low pressure and vacuum ranges.
Specifications
Features include a robust inductive measuring cell, power supply options, and integrated hand pump and metal bellows for precise pressure adjustment.
Features
High-contrast LCD display, integrated valves for venting, and optional analog output are highlighted.
Application Areas
The PC4 is used in various fields such as HVAC, cleanroom technology, and medical technology.
Additional Products
Other products include the Digital handheld manometer LR-Cal Series 2000, Precision barometer XA1000, and Electronic data logger OPUS 20.

Calibration of pressure instruments: Für eine Druckkalibrierung benötigen Sie in der Regel eine Kalibrierdruckquelle sowie ein hinreichend genaues ReferenzDruckmessgerät (Druckkalibrator, Feinmessmanometer, Prozesskalibrator). Bei der Auswahl des Referenzmessgerätes ist darauf zu achten, dass sich die Genauigkeitsangabe in der Regel auf die Messbereichsspanne bezieht (“v.E.“ = vom Endwert). Bei der Auswahl der benötigten Messbereiche für die Referenzgeräte ist dies zu berücksichtigen. To carry out a pressure calibration, normally you need a calibration pressure source together with a sufficiently...
