Automatic Compression Testing Machines (Automatic CTM) Manufacturer

We are Manufacturer, Supplier, Exporter of Automatic Compression Testing Machines (Automatic CTM) and our setup is situated in Kolhapur, Maharashtra, India.

We are Manufacturer, Supplier, Exporter of Automatic Compression Testing Machines (Automatic CTM). Operation of fully automatic compression testing machine is controlled by an intelligent Pace Rate controller. Other facilities include Data Logging, Data Printing, Load hold etc. It has closed loop PID feedback control which uses a high torque stepper motor.
Machine consists of loading unit, an Electrically Operated Hydraulic Pump and an Intelligent Pace Rate Controller. Machine is available in ranges from 50kN to 3000kN capacity. The operation is user friendly with a menu driven interface.

Loading Units
The loading unit is of fully welded construction having a base rosshead and solid slide plates. The hydraulic jack is fixed to base. The platens of the machine are hardened, ground and polished. The upper plate is provided with self-aligning action. To facilitate testing of various size specimens, suitable size spacers are provided.


Pumping Units
The pumping unit has two speeds. It can pump oil from an oil reservoir, fitted with an oil filler plug-cum-dipstick and a drain plug. The pump is driven by an electric motor. AC supply through a junction box provided at the back of the pumping unit. The unit further contains two programmable motors for pace rate control and opening and closing of the release valve. Manual release operation is provided in case of a power cut or any other emergency.
