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
| Feature | LR-Cal LDM 70 | LR-Cal LSP Series |
|---|---|---|
| Product Type | Digital Pressure Gauge | Pressure Comparison Test Pump |
| Main Function | Measures pressure | Generates pressure |
| Display | Digital rotatable display | Requires external reference instrument |
| Pressure Units | Multiple selectable units | Determined by connected reference gauge |
| Calibration | Zero and span adjustment | Used to calibrate other instruments |
| Operation | Three-button menu | Manual pressure generation |
| Typical Use | Process monitoring | Pressure calibration and testing |
| Maintenance | Minimal | Periodic fluid, seal, and filter maintenance |
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.
