LDM 70 vs. LR-Cal LSP Series

While both products are used in pressure-related applications, they serve different purposes.

LDM 70 – Digital Pressure Gauge

The LDM 70 is designed to measure and display pressure. It provides real-time pressure readings and can be used for monitoring processes, equipment, and systems.

LSP Series – Pressure Comparison Test Pump

The LR-Cal LSP series is designed to generate pressure for testing, adjusting, and calibrating pressure instruments. It is commonly used in laboratories, workshops, and field service applications.

Comparison at a Glance

Accuracy

The LDM 70 provides accurate pressure measurements through its integrated digital sensor. The LSP series does not measure pressure directly; instead, it generates stable and controlled pressure for calibration purposes. The overall calibration accuracy of an LSP setup depends on the accuracy of the connected reference instrument.

Conclusion

The LR-Cal LDM 70 and LR-Cal LSP series are complementary products. The LDM 70 measures pressure, while the LSP series generates pressure for testing and calibration. Together, they provide a complete solution for pressure measurement, verification, and calibration across a wide range of industrial applications.

Overview

The LR-Cal LPP 1000 is a compact pneumatic pressure test pump designed for testing, adjusting, and calibrating mechanical and electronic pressure measuring instruments. It generates precise test pressure for comparison measurements, making it ideal for laboratory, workshop, and field applications.

By connecting both the instrument under test and a reference pressure instrument to the pump, the same pressure is applied to both devices. Comparing the readings allows users to verify accuracy, identify deviations, and make adjustments where necessary.

Despite its compact size, the LPP 1000 is easy to operate and provides accurate pressure generation through an integrated fine adjustment valve, enabling precise control of test pressures.

Key Features

• Compact and portable design for laboratory and field use
• Accurate pneumatic pressure generation
• Fine adjustment valve for precise pressure control
• Suitable for mechanical and electronic pressure instruments
• Simple and reliable operation
• Direct mounting of the reference instrument on the pump
• Includes connection hose with freely rotating 1/4″ BSP female adapter
• Ideal for calibration, testing, and verification applications

Benefits

• Fast and reliable pressure calibration
• High measurement confidence through comparison testing
• Lightweight and easy to transport
• User-friendly setup and operation
• Suitable for maintenance, service, and quality assurance programs
• Cost-effective calibration solution

Applications

• Pressure gauge calibration
• Pressure transmitter testing
• Instrument verification and adjustment
• Maintenance and servicing
• Quality control inspections
• Laboratory and workshop calibration
• On-site field calibration
