Servo Control (Pace Rate Control) Compression Testing Machine
Short Discription :
Compression Testing Machines are designed for rugged durability and user-friendly operation, allowing even non-technical personnel to use them reliably. Portable units, being compact, sturdy, and lightweight, enable quality control testing in areas lacking commercial facilities, where transporting larger, heavier machines is challenging….

An analogue compression testing machine (CTM) is a specialized piece of laboratory equipment used primarily in civil engineering and materials science to measure the compressive strength of materials like concrete, bricks, cement mortar, rocks, and other building components. Unlike digital versions, it relies on mechanical gauges (such as Bourdon tube pressure gauges) to display load readings, providing a direct analog readout of the applied force. These machines are typically hydraulic or electro-hydraulic in operation, applying a controlled compressive load to a specimen until failure.
Analogue CTMs are available in various capacities and configurations. Here’s a comparison of typical models based on manufacturer data
Capacity (kN) | Specimen Types Supported | Vertical Clearance (mm) | Piston Travel (mm) | Pump Type |
100–300 | Small cubes (up to 50 mm), mortar | 150–200 | 50–80 | Hand-operated |
250–1000 | Cubes (up to 150 mm), cylinders (up to 160×320 mm) | 300–350 | 100–150 | Electric |
1000–2000 | Standard cubes (150–200 mm), cylinders (150×300 mm) | 350–400 | 150–200 | Electro-hydraulic |
2000–3000 | Large cubes/cylinders, structures | 400–500 | 200–250 | Electric |
Up to 5000 | Heavy-duty specimens, rocks | 500+ | 250+ | Electro-hydraulic |
igital Compression Testing Machines (CTM), often abbreviated as “CTM” in the query, are specialized equipment used primarily in civil engineering and construction to measure the compressive strength of concrete cubes, cylinders, or other materials. These machines apply a controlled load to a test specimen until failure, recording key metrics like peak load, stress (in N/mm² or kg/cm²), and deformation. The “digital models” refer to versions with microprocessor-based displays for precise readings, data logging, and automated calculations, unlike traditional analog gauges.
A Fully Automatic Compression Testing Machine (CTM) is an advanced piece of laboratory equipment used primarily in civil engineering and construction to measure the compressive strength of concrete cubes, cylinders, and other materials. Unlike manual or semi-automatic models, fully automatic CTMs feature closed-loop control systems, servo motors, and software integration for precise pace rate control, automatic test cycling (start, load application, failure detection, and reset), data acquisition, and reporting. They ensure compliance with standards like ASTM C39, EN 12390-4, BS 1881, and IS 516,
with capacities typically ranging from 50 kN to 5000 kN. These
machines minimize human error, enhance repeatability, and often include features like overload protection, thermal printers, and PC connectivity.
