OEM Manufacturer TU-3A01 thermal wax actuator for electric switch valve for Sri Lanka Factory
OEM Manufacturer TU-3A01 thermal wax actuator for electric switch valve for Sri Lanka Factory Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

In this tutorial I’m demonstrating how to use MQ-2/MQ-5 gas sensors with Arduino. These little devices may be used in gas leakage detectors.
The MQ-2 is suitable for detecting LPG, i-butane, propane, methane, hydrogen and even smoke.
The MQ-5 detects LPG, natural gas and town gas.
Many other gas sensors can be used in exactly the same way, e.g. MQ-3, MQ-6 or MQ-135. Just read the datasheet, use the appropriate load resistor and experiment with the “sensorValue” in my Arduino code.

Bio-inspired, Moisture-Powered Hybrid Carbon Nanotube Yarn Muscles. Shi Hyeong Kim et al (2016), Scientific Reports http://dx.doi.org/10.1038/srep23016
Hygromorph artificial muscles are attractive as self-powered actuators driven by moisture from the ambient environment. Previously reported hygromorph muscles have been largely limited to bending or torsional motions or as tensile actuators with low work and energy densities. Herein, we developed a hybrid yarn artificial muscle with a unique coiled and wrinkled structure, which can be actuated by either changing relative humidity or contact with water. The muscle provides a large tensile stroke (up to 78%) and a high maximum gravimetric work capacity during contraction (2.17 kJ kg−1), which is over 50 times that of the same weight human muscle and 5.5 times higher than for the same weight spider silk, which is the previous record holder for a moisture driven muscle. We demonstrate an automatic ventilation system that is operated by the tensile actuation of the hybrid muscles caused by dew condensing on the hybrid yarn. This self-powered humidity-controlled ventilation system could be adapted to automatically control the desired relative humidity of an enclosed space.
