OEM/ODM China TU-020 thermostatic cartridge wax sensor for sanitary ware to United Arab emirates Importers 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.

The Samson Type 3730-3 is an electro-pneumatic valve positioner with HART® communication for use with linear and quarter-turn industrial valves.
The positioner ensures a predetermined assignment of the valve position to the input signal. It compares the input signal received from a control system to the travel or rotational angle of the control valve and issues a corresponding output signal pressure.
Special Features:
Simple attachment to all common linear and rotary actuators with interface for SAMSON direct attachment, NAMUR rib, valves with rod-type yokes according to IEC 60534-6-1 or to rotary actuators according to VDI/ VDE 3845.
Any desired mounting position of the positioner.
Simple single-knob, menu-driven operation.
LCD easy to read in any mounted position due to selectable reading direction.
Configurable with a PC over the SSP interface using the TROVIS-VIEW software.
Variable, automatic start-up with four different initialization modes
Preset parameters – only values deviating from the standard need to be adjusted.
Calibrated travel sensor without gears susceptible to wear.
Sub-initialization mode (substitution) allows the positioner to be started up in case of emergency whilst the plant is running without the valve moving through the whole travel range.
Permanent storage of all parameters in EEPROM (protected against power failure).
Two-wire system with small electrical load between 300 and 350 Ω depending on version.
Adjustable output pressure limitation.
Tight-closing function.
Continuous monitoring of zero point.
Integrated temperature sensor and operating hours counter.
Two standard programmable position alarms.
Self-diagnostics; alarms as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter.
Integrated EXPERTplus diagnostics (u T 8389 EN) suitable for throttling and on/off valves and with additional partial stroke test for valves in safety-instrumented systems.
