Standards

EN 1426; ASTM D5; AASHTO T49

UTB-0130 Fully Automatic Electronic Bitumen Penetrometer with automatic surface detection is used for determination of the needle penetration according to EN 1426, ASTM D5 and AASHTO T49 standards. The penetration depth of the needle is determined with a pulse type electronic measuring system, which is separated from the plunger during the test, this allows the free guidance of the plunger which virtually eliminates friction during the test. UTB-0130 incorporates automatic surface detection which reduces operator based errors and enables performing penetration tests in a quicker way.

Before the start of each test, the measuring system automatically resets, and then the penetration needle moves down to the sample using the electric drive. The plunger is then automatically released onto the sample and raised automatically after the testing period. The test result is displayed on the digital TFT touchscreen.

A magnifying glass and an ultra- bright LED lamp are supplied to assist the operator in addition to automatic surface detection technology. The plunger can easily be removed for weight calibration.

In addition to automatic surface detection, UTB-0130 has a PT 100 temperature sensor to measure the temperature in the transfer dish.

The Automatic Electronic Penetrometer is supplied complete with;

• Penetration Needle, 1 piece.
• Needle holder
• Weights of 50g and 100g

Standards

EN 1427; ASTM D36; AASHTO T53

UTEST UTB-0240 Automatic Ring and Ball/Softening Point Tester is an innovative microprocessor controlled automatic testing device which is used for determining the softening point of bituminous materials using water or glycerol as bath liquid in a range from 30°C to 150°C.

Two bitumen samples casted in shouldered brass rings while being held in horizontal position, temperature is increased under controlled rate acc. to standards. The softening point is the average temperature value of two samples at the time they collapse 25 mm while each carrying a steel ball.

UTB-0240 is equipped with the assembly (UTB-0241), a cooling and heating system, speed controlled magnetic stirrer, motorized beaker lift, optic sensors, temperature probe with its holder.

UTS-0241 Assembly includes a ring holder, a bottom plate, 2pcs. brass rings, 2pcs. brass ball centering guides, 2pcs. stainless steel balls, a glass beaker (UTGG-1335) and a magnetic stirrer bar.

The pouring plate, should be ordered separately.

Two revolutionary features of the UTB-0240 are the immersed heating resistance and the cooling mechanism for the specimen pre-conditioning. Immersed heating resistance provides direct heat transfer to bath liquid without any loss and it is more efficient than the traditional hot plates. Combined with the PID control, temperature gradient is strictly maintained during the test. Cooling unit reduces the temperature of the bath liquid to 5°C automatically. This feature eliminates the dependency to a refrigerator or dealing with ice cubes for test preparation.

To ensure uniform temperature distribution, bath liquid is stirred by an integrated step motor with adjustable speed and a magnetic stirring bar.

Optic sensors instantaneously detect the specimen collapse and the control unit records the softening point temperature value.

Control unit collects data from the temperature probe and governs the cooling and heating systems in PID control loop. Apart from the control, it utilizes user interface functions such as defining test sequences, multiple point & offset calibration of the temperature probe, calibration preparation menu, fine tuning of temperature gradient and visual simulation of the test area.

Main Features

• Uses both water and glycerol as bath liquid (30-150°C)

• Automatic pre-conditioning and test start

• User defined test sequences and automatic finalization of the test

• PID controlled heating and cooling system

• Optic sensors for accurate determination of softening point

• Motorized beaker lift

Safety Features

• Heater is automatically shut down at the end of the test cycle and cooling media and a solenoid valve is automatically opened by the controller.

• Automatic test interruption when there is a probe failure or when the probe is not positioned properly.
