Not every hydraulic press works the same way. Some are built for big, heavy jobs, others for smaller testing work. Because of that, the load cell has to suit the job. If it doesn’t, the numbers you get won’t be right and you might even end up putting stress on the press.
Types of Load Cells for a Hydraulic Press
1. Compression Load Cells (MT701 Compression Load Cell)
The MT701 load cell is the most straightforward choice for hydraulic presses since they're designed specifically to measure pushing or compressing forces.
How they work:
● Convert downward force into electrical signals
● Provide direct measurement of compressive loads
● Handle massive forces while maintaining accuracy
Best applications:
● Standard pressing operations
● Material compression testing
● Heavy-duty industrial manufacturing
Installation: Typically mounted at the base of the press to measure total force applied to the material. This positioning gives clear, direct readings of the pressure being used.
2. Pancake Load Cells (MT711S Stainless Steel Load Cell)
Pancake load cells, also known as low-profile load cells, are a good choice when a press doesn’t have much vertical clearance but still needs dependable measurements.
Key benefits:
● Flat, compact shape that makes them easy to fit into restricted spaces
● Able to measure both compression and tension loads
● Stainless steel models hold up well in damp or corrosive settings
● Provide stable, accurate readings even under heavy forces
Typical uses:
● Presses or testing setups where space is limited
● Jobs where forces may act in more than one direction
● Industrial environments with exposure to water or chemicals
Installation:
In most cases, the cell is fitted between the press ram and the workpiece. Placing it here allows the sensor to register the applied force directly without affecting how the press itself runs.
3. S-Type Load Cells (MT501 Universal Load Cell)
Named for their distinctive S-shape, these versatile MT501 load cells can measure forces in both directions.
Unique features:
● Dual-direction measurement capability
● Handles both compression and tension
● Versatile mounting options
● Excellent for dynamic applications
Best applications:
● Presses requiring force measurement during both pressing and retraction cycles
● Quality control processes where reverse forces matter
● Testing applications with varying force directions
Installation: Can be mounted in various orientations depending on the specific measurement requirements.
4. Specialised Load Cell Types
For unique applications, several specialised options are available:
● Mount directly at the piston or ram end
● Measure force right at the source
● Provide more direct readings
● Ideal for precise force control applications
Hydraulic Load Cells:
● Use fluid-filled chambers instead of electronics
● Perfect for hazardous environments
● Extremely durable construction
● Less accurate than strain gauge types but safer in risky conditions
Choosing the Right Load Cell
Your choice depends on several key factors:
Force Requirements:
- The maximum force your press will apply
- Required accuracy level
- Dynamic vs. static measurements
Physical Constraints:
- Available space for installation
- Mounting requirements
- Environmental conditions
Operational Needs:
- Single-direction vs. dual-direction measurement
- Frequency of use
- Required response time
Why the Right Load Cell Matters
The performance of a hydraulic press depends heavily on the load cell driving its accuracy. The right type ensures reliable readings, prevents unnecessary wear on equipment, and supports safe day-to-day operation.
Whether it’s a standard compression cell, a space-saving pancake design, or a versatile S-type, matching the sensor to the press and its environment makes all the difference. When quality and precision matter, businesses contact Meltrons Australia for load cells built to meet demanding applications.
