The salt spray test chamber creates a highly corrosive environment and tests the long-term effects of salt on objects and materials. The salt spray chamber is commonly used to evaluate the following corrosion properties:
- Phosphorylated finish (followed by paint / primer / varnish / rust inhibitor).
- Zinc plating and zinc alloy plating (see also electroplating)
- Electroplated chrome, nickel, copper, tin
- Non-electrolytically applied to coat (zinc flake coating)
- Organic coating
- The paint coating
The Salt Spray test is a standardized and common corrosion test method. Generally, the materials tested are metals, polymers, and possibly other various types of materials, with surface coatings intended to provide some degree of corrosion protection to the underlying metal increase. The Salt Spray Test is an accelerated corrosion test that (mostly relatively) evaluates the suitability of a coating for use as a protective coating by applying a corrosion attack to the coated sample.
The appearance of corrosion products such as rust and other oxides is assessed after a specified time. The test time depends on the corrosion resistance of the coating. In general, the more corrosion-resistant a coating is, the longer it will take to test for corrosion/rust.
The salt spray test is one of the most widely used and longest established corrosion tests. The first internationally recognized salt spray standard is the ASTM b117. Other important related standards are ISO9227, JIS Z 2371, and ASTM G85. The salt spray (or salt spray) test is a standardized and common corrosion test method used to check the corrosion resistance of materials and surface coatings. The test chamber is designed to perform various types of corrosion tests where the temperature of the sample environment in a dampened state needs to be controlled within certain limits.
The role of environmental testing is to test and demonstrate product suitability, reliability, and durability through exposure to environmental factors such as temperature and humidity. It is necessary to accelerate the environmental impact these products experience in nature.
Digital torque tester
A digital torque tester is a type of transducer, specifically a torque transducer that transforms a torque measurement (reaction, dynamic or rotational) into another physical quantity. In this case, it is an electrical signal that can be measured, converted, and normalized. There are two main categories of torsion sensors: 1. Torque sensors and 2. Reaction force-torque sensors
Rotation Torque Tester (Dynamic or Rotational Torque)
The Rotational (or Dynamic Torque) sensor is used in applications where torque measurements are required on a rotary shaft, motor, or fixed motor. In this case, the converter must rotate on the line attached to the shaft. Rotational torque transducers are equipped with slip rings or wireless electronic devices (contactless sensors) to transmit torque signals during rotation.
The torque converter is widely used as a test tool for engines, torque measuring tools, turbines, and generators for measuring torque. The inter-shaft torque sensor can also be used for feedback control, torque monitoring and test bench efficiency analysis, and torque measurement of rotary shafts using strain gauges.
Rotational torque measurement (also known as rotational torque measurement) is coupled between the motor and the load. As the shaft rotates, the torsion sensor measures the torque generated by the motor in response to the load applied to the rotating shaft. Some rotation sensors have a built-in encoder that measures the angle or the speed while the test is ongoing.
Rotary Torque Transducer is also a crucial part of dynamometers as it provides torque measurement and angular speed (RPM) to easily calculate output power, allowing accurate calculation of motor or engine performance.
Reaction Torque Testers (static)
In some applications, the torque measurement is taken with an in-line rotary sensor and then the torque is transferred to the ground using a reaction torque transducer (static torque measurement).
The reaction torsion sensor has two mounting flanges. One surface is fixed to the ground or a rigid structural member and the other surface is fixed to a rotating shaft or member. The rotation creates a shear force between the flanges. Shear forces are detected by foil strain gauges connected to the sensor carrier and converted into current by the Wheatstone bridge.
