Quality Inspection for TU-1H02 thermal wax actuator for thermostatic radiator valve to Swiss Manufacturers 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.
2. Characteristic
(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.

This video will show how to test thermistors on GE electronic refrigerators made after 2002. A thermistor is a variable resistor that varies resistance with temperature. GE refrigerators use these thermistors to monitor temperature in various locations in the refrigerator. If one is bad the refrigerator will not cool properly.

WD Red just got better! New in NAS…
https://www.span.com/product/45993
WD Red Pro
Storage for 8 to 16 bay NAS solutions
Joining the original color of NAS, WD Red Pro continues the formula of success that has led the WD Red product family by adding support beyond consumer, SOHO, and small business markets into medium and large 8-16 bay business storage systems. WD Red Pro hard drives integrate WD’s exclusive technology, NASware™ 3.0, to provide unparalleled support for drive compatibility, reliability, and performance.
Designed specifically with SMB customers in mind the WD Red family has expanded with the addition of WD Red Pro, which is available for the 8 to 16 bay medium to large-scale NAS environments. With capacities up to 4 TB, WD Red Pro carries a 5-year limited warranty and was engineered to handle the increased workloads from your business.
Exclusive NASware 3.0 technology. Our exclusive advanced firmware technology built into every WD Red Pro drive, NASware 3.0 enables seamless integration, robust data protection and optimal performance for systems operating in the demanding NAS environment.
WD Red is a reflection of the most extensive NAS partner compatibility- testing list that is available on the market.* That means when you buy a NAS enclosure, you can trust that WD Red will be the most compatible drive available. Our pride is in our product and our vision is shared with our customers.
*Data reflects products in production as of July 2014.
NAS for Big Business. Increase the efficiency and productivity of your business with WD Red Pro hard drives for your 8 to 16 bay NAS system. WD Red Pro comes equipped with NASware 3.0, which increases system compatibility allowing for seamless integration with your existing network infrastructure. Add value to your business by enabling your employees to quickly share their files and back up folders reliably with WD Red Pro NAS hard drives in your NAS solution.
8 to 16 Bay Shock Protection. WD Red Pro is equipped with a multi- axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read-write function to compensate and protect the data. This combination of technology further protects the drives in large 8 to 16 bay NAS environments and increases drive reliability.
Vibration Protection. In combination with 3D Active BalanceTM Plus, WD Red Pro also features hardware vibration compensation technology which monitors the drive to correct both linear and rotational vibration in real time, further increasing drive reliability.
Enhanced Accuracy for NAS. For overall enhanced accuracy for NAS, WD Red Pro is also equipped with dual actuator technology which improves positional accuracy over the data tracks and head positioning. StableTracTM technology then secures the motor shaft at both ends to reduce system-induced vibration and stabilize the drive platters for accurate tracking during read and write operations. Both technologies are important for larger 8 to 16 bay NAS environments.
3D Active Balance Plus. Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.
Extended Drive Testing. The 8 to 16 bay NAS environment is very demanding on a hard drive with added vibration, heat and other factors. This is why every WD Red Pro drive is shipped with extended thermal cycle burn-in testing which ensure each drive for extended reliable operation.
Error Recovery Prevention. Built specifically for RAID and NAS environments, WD Red Pro drives come equipped with error recovery controls as part of NASware 3.0, which prevents the drive from fallout in RAID applications.
Longer Warranty Coverage. Complimenting WD Red at a 3-year limited warranty, WD Red Pro offers longer warranty coverage with a 5-year limited warranty for an even greater peace of mind.
NAS Compatibility. Since your NAS system is always on, a highly reliable drive is essential. With a 35% MTBF improvement over standard drives, the WD Red drive with NASware 3.0 is designed for the 24×7 environment.
Ideal for: Specifically designed and tested for medium to large business NAS applications with 8 – 16 bays.
For systems that use less than 8 bays, please consider WD Red hard drives.*
